  • WPF application with MS Access database as a data source

    - by Kay Zed
    I have a Microsoft Access 2010 database. Now, using Visual Studio 2010, I want to create a WPF application and add the database as a data source. The app will have a window with a frame that provides navigation through pages. No problem so far. But: -What is the right way to set up the database in this scenario? Tables only? Or must everything go via queries? (VS2010 talks about views which I assume (?) are queries) -Database data must be updatable and records can be added. Some relationships go through link tables (many-to-many) and there are nullable foreign key relationships. Must I take manual steps to make it work? -While adding the data source VS2010 created an xsd from my Access database. I think the xsd might need further tweaking for the application to work the right way. What if I change my Access database design, I'd have to regenerate the xsd again as well. Is this right, and is it the way it is usually done? OR, should I let the original Access database go and give the application the capability to create new empty databases? -How do you provide controls in a page to step through the records in a table? Is there a special database control? -What is the way (WPF class?) to load records into the data context that displays in a page? (At this level it probably does not matter what type of data source it is.)

  • Translating delegate usage from C# to VB

    - by Homeliss
    ContactManager.PostSolve += PostSolve; I am having a problem converting this piece of code from C# to VB.NET. ContactManager.PostSolve is a delegate. I tried the following but it doesn't work, it says PostSolve is not an event of ContactManager: AddHandler ContactManager.PostSolve, AddressOf PostSolve The following works, but this only allows me to have one handler for the delegate: ContactManager.PostSolve = new PostSolveDelegate(AddressOf PostSolve) Is there a way for me to do the same thing in VB that was done in the first piece of code? Thanks!

  • Debug .Net Framework's source code only shows disassembly in Visual Studio 2010

    - by jdecuyper
    Hi! I'm trying to debug .Net Framework's source code using Visual Studio 2010 Professional. I followed the steps described in Raj Kaimal's post but I must be doing something wrong since the only code I'm getting to see is the disassembly code: As you can see in the image, the Go to Source Code and the Load Symbols options are disabled. Nevertheless, symbols are downloaded from Microsoft's server since I can see them inside the local cache directory. The code I'm debugging goes as follow: var wr = WebRequest.Create("http://www.google.com"); Console.WriteLine("Web request created"); var req = wr.GetRequestStream(); Console.Read(); When I hit F11 to step into the first line of code, a window pops us looking for the "WebRequst.cs" file inside "f:\dd\ndp\fx\src\Net\System\Net\WebRequest.cs" which does not exists on my machine. What am I missing? Thanks a lot for your help.

  • ExpectedException on TestMethod Visual Studio 2010

    - by Joop
    Today I upgraded my solution with all the underlying projects from VS2008 to VS2010. Everything went well except for my unit tests. First of all only the web projects had as target framework .NET 4. All the other projects still had .NET 3.5. I changed them all to .NET 4. Now when I debug my unit tests it breaks on every exception. In 2008 it just wouldn't pass and tell me that an exception occurred. Even when I have the ExpectedException attribute defined it stops debugging on every exception. And example of one of my tests: [TestMethod] [ExpectedException(typeof(EntityDoesNotExistException))] public void ConstructorTest() { AddressType type = new AddressType(int.MaxValue); } The EntityDoesNotExistException is a custom exception and inherits Exception.

  • Platform configuration for projects in VS 2010

    - by Thomas Wanner
    I have a third-party project type in Visual Studio which for some reason only supports the .NET Platform configuration for the build, for all other (standard C#) projects in the solution I only have AnyCPU. Unfortunately, ever since upgrading to VS 2010 it produces following error when built : Error 39 The OutputPath property is not set for project 'ReferencedBusinessProject.csproj'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='Debug' Platform='.NET'. This error may also appear if some other project is trying to follow a project-to-project reference to this project, this project has been unloaded or is not included in the solution, and the referencing project does not build using the same or an equivalent Configuration or Platform. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets 483 10 CustomTypeProject It's pretty much descriptive in what is missing but I haven't found any way to fix it so far. Do you have any idea how this can be resolved or what can be the problem ?

  • Why does adding a reference to project targeting .NET Framework 4.0 fail?

    - by Malcolm Post
    We have two projects that are both class libraries. Project 1 is a VS 2008 project and targets the .NET Framework 3.5. Project 2 is a VS 2010 (release candidate) project that targets the .NET Framework 4.0. When I try to add a reference to Project 2 in Project 1, it fails with a less than informative error message. I know that if I change the target Framework for Project 2 to 3.5, then adding the reference will work. My question is, if I don't change the target frameworks, but convert Project 1 to VS 2010, will the referencing work? Stated another way, is there some inherent incompatiblity between class libraries targeting different framework versions, or is it failing for me because VS 2008 doesn't know about the 4.0 framework?

  • Using the same modules in multiple projects

    - by Andreas Vinther
    I'm using Visual Studio 2010 and coding in VB.NET. My problem is that I've collected all the modules I've written and intend to reuse and placed them in a separate folder. When I want to add a module from the above folder to any given project, it takes a copy of the module and places in the project's source code folder, instead of referencing the module in the folder containing all the other modules. Is it possible to include a module in my project and leave it in the folder with all the other modules, so that when I improve upon a module, it'll affect all the projects that uses/references that module. Instead of me having to manually copy the new module to all the projects that uses/references the module. Right now I have multiple instances of the exact same module that i need to update manually when I improve code or add functionality?

    - by Chris Hardy (ChrisNTR)
    This past weekend, I headed up to Glasgow thanks to Plip for driving and Dave Sussman for some light entertainment to do a session on C# on the iPhone with MonoTouch. I had already presented a session similar to this one at DDD8 in Reading, which you can watch on Vimeo ( http://vimeo.com/9150434 ) but in this session I covered more topics such as the new 3.3.1 section of the new terms of service Apple released. I also showed a Twitter example written in MonoTouch, which was reused from the DDD8 session...(read more)

  • An abundance of LINQ queries and expressions using both the query and method syntax.

    - by nikolaosk
    In this post I will be writing LINQ queries against an array of strings, an array of integers.Moreover I will be using LINQ to query an SQL Server database. I can use LINQ against arrays since the array of strings/integers implement the IENumerable interface. I thought it would be a good idea to use both the method syntax and the query syntax. There are other places on the net where you can find examples of LINQ queries but I decided to create a big post using as many LINQ examples as possible. We...(read more)

  • TechEd Israel 2010 may only accept speakers from sponsors

    - by RoyOsherove
    A month or so ago, Microsoft Israel started sending out emails to its partners and registered event users to “Save the date!” – Micraoft Teched Israel is coming, and it’s going to be this november! “Great news” I thought to myself. I’d been to a couple of the MS teched events, as a speaker and as an attendee, and it was lovely and professionally done. Israel is an amazing place for technology and development and TechEd hosted some big names in the world of MS software. A couple of weeks ago, I was shocked to hear from a couple of people that Microsoft Israel plans to only accept non-MS teched speakers, only from sponsors of the event. That means that according to the amount that you have paid, you get to insert one or more of your own selected speakers as part of teched. I’ve spent the past couple of weeks trying to gather more evidence of this, and have gotten some input from within MS about this information. It looks like that is indeed the case, though no MS rep. was prepared to answer any email I had publicly. If they approach me now I’d be happy to print their response. What does this mean? If this is true, it means that Microsoft Israel is making a grave mistake – They are diluting the quality of the speakers for pure money factors. That means, that as a teched attendee, who paid good money, you might be sitting down to watch nothing more that a bunch of infomercials, or sub-standard speakers – since speakers are no longer selected on quality or interest in their topic. They are turning the conference from a learning event to a commercial driven event They are closing off the stage to the community of speakers who may not be associated with any organization  willing to be a sponsor They are losing speakers (such as myself) who will not want to be part of such an event. (yes – even if my company ends up sponsoring the event, I will not take part in it, Sorry Eli!) They are saying “F&$K you” to the community of MVPs who should be the people to be approached first about technical talks (my guess is many MVPs wouldn’t want to talk at an event driven that way anyway ) I do hope this ends up not being true, but it looks like it is. MS Israel had already done such a thing with the Developer Days event previouly held in Israel – only sponsors were allowed to insert speakers into the event. If this turns out to be true I would urge the MS community in Israel to NOT TAKE PART AT THIS EVENT in any form (attendee, speaker, sponsor or otherwise). by taking part, you will be telling MS Israel it’s OK to piss all over the community that they are quietly suffocating anyway. The MVP case MS Israel has managed to screw the MVP program as well. MS MVPs (I’m one) have had a tough time here in Israel the past couple of years. ever since yosi taguri left the blue badge ranks, there was not real community leader left. Whoever runs things right now has their eyes and minds set elsewhere, with the software MVP community far from mind and heart. No special MVP events (except a couple of small ones this year). No real MVP leadership happens here, with the MVP MEA lead (Ruari) being on a remote line, is not really what’s needed. “MVP? What’s that?” I’m sure many MS Israel employees would say. Exactly my point. Last word I’ve been disappointed by the MS machine for a while now, but their slowness to realize what real community means in the past couple of years really turns me off. Maybe it’s time to move on. Maybe I shouldn’t be chasing people at MS Israel begging for a room to host the Agile Israel user group. Maybe it’s time to say a big bye bye and start looking at a life a bit more disconnected.

  • Join the Dark Side of Visual Studio 2010

    - by InfinitiesLoop
    Hard to believe it’s been so long, but it was almost 4 years ago when I published Join the Dark Side of Visual Studio . That was when a lot of people were still using VS2003, and importing and exporting environment settings required a custom add-in, VSStyler, which has since fallen off the planet and is hard to find (link, anyone? Let me know). Three versions of VS later, and I’m still using and loving the dark side. Pleased, I am (haha). In fact, that article for one reason or another is still one...(read more)

  • First class language in Visual Studio 2010 using F#

    - by Aamir Hasan
     F# is a strongly-typed language like C#.It is light weight syntax just like Python.It give you math-like feel. let data = (1,2,3)   let rotations (x, y, z) =     [ (x, y, z);       (z, x, y);       (y, z, x) ]   let derivative f x =     let p1 = f (x - 0.05)     let p2 = f (x + 0.05)     (p2 - p1) / 0.1   let f x = 2.0*x*x - 6.0*x + 3.0   let df = derivative f   System.Console.WriteLine("The derivative of f at x=4 is {0}", df 4.0)   This program will print: “The derivative of f at x=4 is 10”That’s a quick look at just a few of the exciting features of F#.  For more on F#, visit the F# Development Center on MSDN.

  • IL and case-sensitivity

    - by Ali .NET
    Quoted from A Brief Introduction To IL code, CLR, CTS, CLS and JIT In .NET CLS stands for Common Language Specifications. It is a subset of CTS. CLS is a set of rules or guidelines which if followed ensures that code written in one .NET language can be used by another .NET language. For example one rule is that we cannot have member functions with same name with case difference only i.e we should not have add() and Add(). This may work in C# because it is case-sensitive but if try to use that C# code in VB.NET, it is not possible because VB.NET is not case-sensitive. Based on above text I want to confirm two points here: Does the case-sensitivity of IL is a condition for member functions only, and not for member properties? Is it true that C# wouldn't be inter-operable with VB.NET if it didn't take care of the case sensitivity?

  • Access Services in SharePoint Server 2010

    - by Wayne
    Another SharePoint Server 2010 feature which cannot go unnoticed is the Access Services. Access Services is a service in SharePoint Server 2010 that allows administrators to view, edit, and configure a Microsoft access application within a Web Browser. Access Services settings support backup and recovery, regardless of whether there is a UI setting in Central Administration. However, backup and recovery only apply to service-level and administrative-level settings; end-user content from the Access application is not backed up as part of this process. Access Services has Windows PowerShell functionality that can be used to provide the service that uses settings from a previous backup; configure and manage macro and query setting; manage and configure session management; and configure all the global settings of the service. Key Benefits of SharePoint Server Access Services Easier Access to right tools: The enhanced, customizable Ribbon in Access 2010 makes it easy to uncover more commands so you can focus on the end product. The new Microsoft Office BackstageTM view is yet another feature that can help you easily analyze and document your database, share, publish, and customize your Access 2010 experience, all from one convenient location. Helps build database effortlessly and quickly: Out-of-the box templates and reusable components make Access Services the fastest, simplest database solution available. It helps find new pre-built templates which you can start using without customization or select templates created by your peers in the Access online community and customize them to meet your needs. It builds your databases with new modular components. New Application Parts enable you to add a set of common Access components, such as a table and form for task management, to your database in a few simple clicks. Database navigation is now simplified. It creates Navigation Forms and makes your frequently used forms and reports more accessible without writing any code or logic. Create Impactful forms and reports: Whether it's an inventory of your assets or customer sales database, Access 2010 brings the innovative tools you'd expect from Microsoft Office. Access Services easily spot trends and add emphasis to your data. It quickly create coordinating database forms and reports and bring the Web into your database. Obtain a centralized landing pad for your data: Access 2010 offers easy ways to bring your data together and help increase work quality. New technologies help break down barriers so you can share and work together on your databases, making you or your team more efficient and productive. Add automation and complex expressions: If you need a more robust database design, such as preventing record deletion if a specific condition is met or if you need to create calculations to forecast your budget, Access 2010 empowers you to be your own developer. The enhanced Expression Builder greatly simplifies your expression building experience with IntelliSense®. With the revamped Macro Designer, it's now even easier for you to add basic logic to your database. New Data Macros allow you to attach logic to your data, centralizing the logic on the table, not the objects that update your data. Key features of Access Services 2010 - Access database content through a Web browser: Newly added Access Services on Microsoft SharePoint Server 2010 enables you to make your databases available on the Web with new Web databases. Users without an Access client can open Web forms and reports via a browser and changes are automatically synchronized. - Simplify how you access the features you need: The Ribbon, improved in Access 2010, helps you access commands even more quickly by enabling you to customize or create your own tabs. The new Microsoft Office Backstage view replaces the traditional File menu to provide one central, organized location for all of your document management tasks. - Codeless navigation: Use professional looking web-like navigation forms to make frequently used forms and reports more accessible without writing any code or logic. - Easily reuse Access items in other databases: Use Application Parts to add pre-built Access components for common tasks to your database in a few simple clicks. You can also package common database components, such as data entry forms and reports for task management, and reuse them across your organization or other databases. - Simplified formatting: By using Office themes you can create coordinating professional forms and reports across your database. Simply select a familiar and great looking Office theme, or design your own, and apply it to your database. Newly created Access objects will automatically match your chosen theme.

  • SO-Aware Service Explorer – Configure and Export your services from VS 2010 into the repository

    - by cibrax
    We have introduced a new Visual Studio tool called “Service Explorer” as part of the new SO-Aware SDK version 1.3 to help developers to configure and export any regular WCF service into the SO-Aware service repository. This new tool is a regular Visual Studio Tool Window that can be opened from “View –> Other Windows –> Services Explorer”. Once you open the Services Explorer, you will able to see all the available WCF services in the Visual Studio Solution. In the image above, you can see that a “HelloWorld” service was found in the solution and listed under the Tool window on the left. There are two things you can do for a new service in tool, you can either export it to SO-Aware repository or associate it to an existing service version in the repository. Exporting the service to SO-Aware means that you want to create a new service version in the repository and associate the WCF service WSDL to that version. Associating the service means that you want to use a version already created in SO-Aware with the only purpose of managing and centralizing the service configuration in SO-Aware. The option for exporting a service will popup a dialog like the one bellow in which you can enter some basic information about the service version you want to create and the repository location. The option for associating a service will popup a dialog in which you can pick any existing service version repository and the application configuration file that you want to keep in sync for the service configuration. Two options are available for configuring a service, WCF Configuration or SO-Aware. The WCF Configuration option just tells the tool that the service will use the standard WCF configuration section “system.serviceModel” but that section must be updated and kept in sync with the configuration selected for the service in the repository. The SO-Aware configuration option will tell the tool that the service configuration will be resolved at runtime from the repository. For example, selecting SO-Aware will generate the following configuration in the selected application configuration file, <configuration> <configSections> <section name="serviceRepository" type="Tellago.ServiceModel.Governance.ServiceConfiguration.ServiceRepositoryConfigurationSection, Tellago.ServiceModel.Governance.ServiceConfiguration" /> </configSections> <serviceRepository url="http://localhost/soaware/servicerepository.svc"> <services> <service name="ref:HelloWorldService(1.0)@dev" type="SOAwareSampleService.HelloWorldService" /> </services> </serviceRepository> </configuration> As you can see the tool represents a great addition to the toolset that any developer can use to manage and centralize configuration for WCF services. In addition, it can be combined with other useful tools like WSCF.Blue (Web Service Contract First) for generating the service artifacts like schemas, service code or the service WSDL itself.

  • WCF errors in VS 2010/.Net 4 using sample publish/subscribe app from IDesign website

    - by Bill
    I am attempting to compile/run a sample WCF application from Juval Lowy's website (author of Programming WCF Services & founder of IDesign). The application is an example of a publish/subscribe 'traffic-light' application that requires using VS 2010/.Net 4. This is my first attempt at using anything other than VS 2008/Net 3.5. Initially I recieved the following binding error: "Configuration binding extension 'system.serviceModel/bindings/ netOnewayRelayBinding' could not be found." This error appeared to be resolved by amending the .Net 4 machine.config file, to incorporate the following references from the .Net 2 machine.config file. <xml> <bindingElementExtensions> <add name="tcpRelayTransport" type="Microsoft.ServiceBus.Configuration.TcpRelayTransportElement, Microsoft.ServiceBus, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add name="httpRelayTransport" type="Microsoft.ServiceBus.Configuration.HttpRelayTransportElement, Microsoft.ServiceBus, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add name="httpsRelayTransport" type="Microsoft.ServiceBus.Configuration.HttpsRelayTransportElement, Microsoft.ServiceBus, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add name="onewayRelayTransport" type="Microsoft.ServiceBus.Configuration.RelayedOnewayTransportElement, Microsoft.ServiceBus, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add name="webMessageEncoding" type="System.ServiceModel.Configuration.WebMessageEncodingElement, System.ServiceModel.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> <add name="context" type="System.ServiceModel.Configuration.ContextBindingElementExtensionElement, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> <add name="byteStreamMessageEncoding" type="System.ServiceModel.Configuration.ByteStreamMessageEncodingElement, System.ServiceModel.Channels, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> <add name="discoveryClient" type="System.ServiceModel.Discovery.Configuration.DiscoveryClientElement, System.ServiceModel.Discovery, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> </bindingElementExtensions> <bindingExtensions> <add name="webHttpBinding" type="System.ServiceModel.Configuration.WebHttpBindingCollectionElement, System.ServiceModel.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> <add name="basicHttpContextBinding" type="System.ServiceModel.Configuration.BasicHttpContextBindingCollectionElement, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> <add name="basicHttpRelayBinding" type="Microsoft.ServiceBus.Configuration.BasicHttpRelayBindingCollectionElement, Microsoft.ServiceBus, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add name="webHttpRelayBinding" type="Microsoft.ServiceBus.Configuration.WebHttpRelayBindingCollectionElement, Microsoft.ServiceBus, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add name="ws2007HttpRelayBinding" type="Microsoft.ServiceBus.Configuration.WS2007HttpRelayBindingCollectionElement, Microsoft.ServiceBus, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add name="netTcpRelayBinding" type="Microsoft.ServiceBus.Configuration.NetTcpRelayBindingCollectionElement, Microsoft.ServiceBus, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add name="netOnewayRelayBinding" type="Microsoft.ServiceBus.Configuration.NetOnewayRelayBindingCollectionElement, Microsoft.ServiceBus, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add name="netEventRelayBinding" type="Microsoft.ServiceBus.Configuration.NetEventRelayBindingCollectionElement, Microsoft.ServiceBus, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> <add name="wsHttpContextBinding" type="System.ServiceModel.Configuration.WSHttpContextBindingCollectionElement, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> <add name="netTcpContextBinding" type="System.ServiceModel.Configuration.NetTcpContextBindingCollectionElement, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> </bindingExtensions> Unfortunately running the application results in the following security error: An error occurred creating the configuration section handler for system.serviceModel/client: That assembly does not allow partially trusted callers. (\TrafficLights\TrafficController\bin\Debug\TrafficController.vshost.exe.Config line 4) The sample source code is available for download at the following link: http://www.idesign.net/idesign/DesktopDefault.aspx?tabindex=-1&tabid=19&download=226 I know that Juval's code is not at fault here and that it must be something I'm doing wrong with my VS 2010 configuration. I have not been able to find a solution online. Could someone please steer me in the right direction as to how best to deal with this issue?

  • .NET: Interface Problem VB.net Getter Only Interface

    - by snmcdonald
    Why does an interface override a class definition and violate class encapsulation? I have included two samples below, one in C# and one in VB.net? VB.net Module Module1 Sub Main() Dim testInterface As ITest = New TestMe Console.WriteLine(testInterface.Testable) ''// Prints False testInterface.Testable = True ''// Access to Private!!! Console.WriteLine(testInterface.Testable) ''// Prints True Dim testClass As TestMe = New TestMe Console.WriteLine(testClass.Testable) ''// Prints False ''//testClass.Testable = True ''// Compile Error Console.WriteLine(testClass.Testable) ''// Prints False End Sub End Module Public Class TestMe : Implements ITest Private m_testable As Boolean = False Public Property Testable As Boolean Implements ITest.Testable Get Return m_testable End Get Private Set(ByVal value As Boolean) m_testable = value End Set End Property End Class Interface ITest Property Testable As Boolean End Interface C# using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace InterfaceCSTest { class Program { static void Main(string[] args) { ITest testInterface = new TestMe(); Console.WriteLine(testInterface.Testable); testInterface.Testable = true; Console.WriteLine(testInterface.Testable); TestMe testClass = new TestMe(); Console.WriteLine(testClass.Testable); //testClass.Testable = true; Console.WriteLine(testClass.Testable); } } class TestMe : ITest { private bool m_testable = false; public bool Testable { get { return m_testable; } private set { m_testable = value; } } } interface ITest { bool Testable { get; set; } } } More Specifically How do I implement a interface in VB.net that will allow for a private setter. For example in C# I can declare: class TestMe : ITest { private bool m_testable = false; public bool Testable { get { return m_testable; } private set //No Compile Error here! { m_testable = value; } } } interface ITest { bool Testable { get; } } However, if I declare an interface property as readonly in VB.net I cannot create a setter. If I create a VB.net interface as just a plain old property then interface declarations will violate my encapsulation. Public Class TestMe : Implements ITest Private m_testable As Boolean = False Public ReadOnly Property Testable As Boolean Implements ITest.Testable Get Return m_testable End Get Private Set(ByVal value As Boolean) ''//Compile Error m_testable = value End Set End Property End Class Interface ITest ReadOnly Property Testable As Boolean End Interface So my question is, how do I define a getter only Interface in VB.net with proper encapsulation? I figured the first example would have been the best method. However, it appears as if interface definitions overrule class definitions. So I tried to create a getter only (Readonly) property like in C# but it does not work for VB.net. Maybe this is just a limitation of the language?
