  • Building extensions for Expression Blend 4 using MEF

    - by Timmy Kokke
    Introduction Although it was possible to write extensions for Expression Blend and Expression Design, it wasn’t very easy and out of the box only one addin could be used. With Expression Blend 4 it is possible to write extensions using MEF, the Managed Extensibility Framework. Until today there’s no documentation on how to build these extensions, so look thru the code with Reflector is something you’ll have to do very often. Because Blend and Design are build using WPF searching the visual tree with Snoop and Mole belong to the tools you’ll be using a lot exploring the possibilities.  Configuring the extension project Extensions are regular .NET class libraries. To create one, load up Visual Studio 2010 and start a new project. Because Blend is build using WPF, choose a WPF User Control Library from the Windows section and give it a name and location. I named mine DemoExtension1. Because Blend looks for addins named *.extension.dll  you’ll have to tell Visual Studio to use that in the Assembly Name. To change the Assembly Name right click your project and go to Properties. On the Application tab, add .Extension to name already in the Assembly name text field. To be able to debug this extension, I prefer to set the output path on the Build tab to the extensions folder of Expression Blend. This means that everything that used to go into the Debug folder is placed in the extensions folder. Including all referenced assemblies that have the copy local property set to false. One last setting. To be able to debug your extension you could start Blend and attach the debugger by hand. I like it to be able to just hit F5. Go to the Debug tab and add the the full path to Blend.exe in the Start external program text field. Extension Class Add a new class to the project.  This class needs to be inherited from the IPackage interface. The IPackage interface can be found in the Microsoft.Expression.Extensibility namespace. To get access to this namespace add Microsoft.Expression.Extensibility.dll to your references. This file can be found in the same folder as the (Expression Blend 4 Beta) Blend.exe file. Make sure the Copy Local property is set to false in this reference. After implementing the interface the class would look something like: using Microsoft.Expression.Extensibility; namespace DemoExtension1 { public class DemoExtension1:IPackage { public void Load(IServices services) { } public void Unload() { } } } These two methods are called when your addin is loaded and unloaded. The parameter passed to the Load method, IServices services, is your main entry point into Blend. The IServices interface exposes the GetService<T> method. You will be using this method a lot. Almost every part of Blend can be accessed thru a service. For example, you can use to get to the commanding services of Blend by calling GetService<ICommandService>() or to get to the Windowing services by calling GetService<IWindowService>(). To get Blend to load the extension we have to implement MEF. (You can get up to speed on MEF on the community site or read the blog of Mr. MEF, Glenn Block.)  In the case of Blend extensions, all that needs to be done is mark the class with an Export attribute and pass it the type of IPackage. The Export attribute can be found in the System.ComponentModel.Composition namespace which is part of the .NET 4 framework. You need to add this to your references. using System.ComponentModel.Composition; using Microsoft.Expression.Extensibility;   namespace DemoExtension1 { [Export(typeof(IPackage))] public class DemoExtension1:IPackage { Blend is able to find your addin now. Adding UI The addin doesn’t do very much at this point. The WPF User Control Library came with a UserControl so lets use that in this example. I just drop a Button and a TextBlock onto the surface of the control to have something to show in the demo. To get the UserControl to work in Blend it has to be registered with the WindowService.  Call GetService<IWindowService>() on the IServices interface to get access to the windowing services. The UserControl will be used in Blend on a Palette and has to be registered to enable it. This is done by calling the RegisterPalette on the IWindowService interface and passing it an identifier, an instance of the UserControl and a caption for the palette. public void Load(IServices services) { IWindowService windowService = services.GetService<IWindowService>(); UserControl1 uc = new UserControl1(); windowService.RegisterPalette("DemoExtension", uc, "Demo Extension"); } After hitting F5 to start debugging Expression Blend will start. You should be able to find the addin in the Window menu now. Activating this window will show the “Demo Extension” palette with the UserControl, style according to the settings of Blend. Now what? Because little is publicly known about how to access different parts of Blend adding breakpoints in Debug mode and browsing thru objects using the Quick Watch feature of Visual Studio is something you have to do very often. This demo extension can be used for that purpose very easily. Add the click event handler to the button on the UserControl. Change the contructor to take the IServices interface and store this in a field. Set a breakpoint in the Button_Click method. public partial class UserControl1 : UserControl { private readonly IServices _services;   public UserControl1(IServices services) { _services = services; InitializeComponent(); }   private void button1_Click(object sender, RoutedEventArgs e) { } } Change the call to the constructor in the load method and pass it the services property. public void Load(IServices services) { IWindowService service = services.GetService<IWindowService>(); UserControl1 uc = new UserControl1(services); service.RegisterPalette("DemoExtension", uc, "Demo Extension"); } Hit F5 to compile and start Blend. Got to the window menu and start show the addin. Click on  the button to hit the breakpoint. Now place the carrot text _services text in the code window and hit Shift+F9 to show the Quick Watch window. Now start exploring and discovering where to find everything you need.  More Information The are no official resources available yet. Microsoft has released one extension for expression Blend that is very useful as a reference, the Microsoft Expression Blend® Add-in Preview for Windows® Phone. This will install a .extension.dll file in the extension folder of Blend. You can load this file with Reflector and have a peek at how Microsoft is building his addins. Conclusion I hope this gives you something to get started building extensions for Expression Blend. Until Microsoft releases the final version, which hopefully includes more information about building extensions, we’ll have to work on documenting it in the community.

  • VG.net 8.5 Released

    - by Frank Hileman
    We have released version 8.5 of the VG.net vector graphics system. This release supports Visual Studio 2013. Companies who purchased a VG.net license after October 1, 2013, are eligible for a free upgrade. We will be sending you an email. There is one cosmetic problem which wasted our time, as we could not find a work around. It occurs when your display is set to a high DPI. You can see the problem in the image of the toolbox below, which uses a DPI of 125%, on Windows 7: The ToolboxItem class accepts only Bitmaps with a size of 16x16. We tried many sizes and many bitmap formats. As you can see, this tiny Bitmap is then scaled by the toolbox, and the scaling algorithm adds artifacts. This is an "improvement" Microsoft recently added to Visual Studio 2013.

  • How can I recover Google Chrome extensions, settings after a Linux crash?

    - by Norman Ramsey
    I'm running Google Chrome 5.0.307.11 (Official Build 39572) beta on Debian Linux (lenny) kernel version 2.6.26-2-686. The machine is a laptop (Lenovo Thinkpad X300) and sometimes it freezes, usually shortly after wakeup from sleep. The only cure is the power button, but when I restart my Google Chrome web browser after such an event, Settings on the Options menu revert to defaults. Chrome removes all the extensions from ~/.config/google-chrome/Default/Extensions, leaving me with no extensions. The set of "pages last open" is lost. I'd love to know how to poke at the file system in order to recover any or all of this information, especially my extensions. It is a pain to re-do everything by hand each time. How can I recover Google Chrome's extensions and settings after a Linux crash?

  • Why does installing gnome shell extensions from extensions.gnome.org fail silently?

    - by Pascal
    On a fresh Ubuntu install (12.04, 64-bit), after installing gnome-shell, I've tried to install some extensions from extensions.gnome.org but got no result. I've tried with Firefox and Chromium and got the same issue. Open any extension page on extensions.gnome.org. Switch extension to "ON". Agree with confirmation about installation. Nothing happens and nothing has been installed (.local/share/gnome-shell/extensions is empty). I've checked .xsession-errors, Firefox's javascript console, gnome-shell console errors (Alt-F2 + looking glass). There isn't any trace of any error.

  • How can I figure out which PHP extensions aren't being used?

    - by Tom Marthenal
    I manage a server (running Ubuntu) which hosts our client's sites with a few dozen different PHP-based websites, mostly small sites but also some installations of CMSes and forums. I used the get_loaded_extensions() method to see what extensions I have loaded. To help streamline the server (remove unnecessary extensions to make upgrading easier and marginally improve speed), I'd like to remove extensions that aren't being used by any of the sites. I currently have 54 different extensions loaded. I can easily eliminate some of these from the list which I know are used, but others I am less sure about. Is there some way that I can see extensions which have not been used recently?

  • Keyboard locking up in Visual Studio 2010, Part 2

    - by Jim Wang
    Last week I posted about looking into the keyboard locking up issue in Visual Studio.  So far it looks like not a lot of people have replied to provide concrete repro steps, which confirms my suspicion that this is somewhat of a random issue. So at this point, I have a couple of choices.  I can either wait for somebody in the community to provide a repro of the problem that I can reliably run into, or I can do the work myself. I’m going to do both, so while I’m waiting for more possible bug reports, I’m going to write a tool that models the behavior of a typical Visual Studio user and use that to hopefully isolate the problem. I’ve chosen to go with this path since given the information in the bug reports, it seems people hit the issue with many different configurations in many different scenarios.  This means that me sitting down without any solid repro steps is likely not going to be a good use of time.  Instead, I’m going to go with a model-based testing approach where I will define a series of actions that a user in VS can do, and then proceed to run my model.  I’ll let you guys know how this works out for isolating bugs :) I’m using an internal tool for the model engine and AutoIt for the UI automation (I want something lightweight for a one-off).  One of the challenges will be getting feedback: AutoIt is great at driving, but not so great at understanding what success and failure means.

  • Overwhelmed by complex C#/ASP.NET project in Visual Studio 2008

    - by Darren Cook
    I have been hired as a junior programmer to work on projects that extend existing functionality in a very large, complex solution. The code base consists of C#, ASP.NET, jQuery, javascript, html and xml. I have some knowledge of all these in addition to fair knowledge of object-oriented programming and its fundamental concepts of inheritance, abstraction, polymorphism and encapsulation. I can follow code up through its base classes, interfaces, abstract classes and understand a large part of the code that I read while doing this. However, this solution is so humongous and so many things get tied together whenever I navigate through the code that I feel absolutely overwhelmed. I often find myself unable to fully follow everything that is going on with objects being serialized, large amounts of C# and javascript operating on the same pages and methods being called from template files that consist mainly of markup. I love learning about code, but trying to deal with this really stresses me out. Additionally, I do know that a significant amount of unit testing has been done but I know nothing about unit testing or how to utilize it. Any advice anyone could offer me regarding dealing with a large code base while using Visual Studio 2008 would be greatly appreciated. Are there tools that I can use to help get a handle on what is going on? Perhaps there are things even in Visual Studio that I am not aware of. How can I follow the code to low level functionality in order to get a better grasp of what is going on at a high level?

  • Windows Azure: Announcing release of Windows Azure SDK 2.2 (with lots of goodies)

    - by ScottGu
    Earlier today I blogged about a big update we made today to Windows Azure, and some of the great new features it provides. Today I’m also excited to also announce the release of the Windows Azure SDK 2.2. Today’s SDK release adds even more great features including: Visual Studio 2013 Support Integrated Windows Azure Sign-In support within Visual Studio Remote Debugging Cloud Services with Visual Studio Firewall Management support within Visual Studio for SQL Databases Visual Studio 2013 RTM VM Images for MSDN Subscribers Windows Azure Management Libraries for .NET Updated Windows Azure PowerShell Cmdlets and ScriptCenter The below post has more details on what’s available in today’s Windows Azure SDK 2.2 release.  Also head over to Channel 9 to see the new episode of the Visual Studio Toolbox show that will be available shortly, and which highlights these features in a video demonstration. Visual Studio 2013 Support Version 2.2 of the Window Azure SDK is the first official version of the SDK to support the final RTM release of Visual Studio 2013. If you installed the 2.1 SDK with the Preview of Visual Studio 2013 we recommend that you upgrade your projects to SDK 2.2.  SDK 2.2 also works side by side with the SDK 2.0 and SDK 2.1 releases on Visual Studio 2012: Integrated Windows Azure Sign In within Visual Studio Integrated Windows Azure Sign-In support within Visual Studio is one of the big improvements added with this Windows Azure SDK release.  Integrated sign-in support enables developers to develop/test/manage Windows Azure resources within Visual Studio without having to download or use management certificates.  You can now just right-click on the “Windows Azure” icon within the Server Explorer inside Visual Studio and choose the “Connect to Windows Azure” context menu option to connect to Windows Azure: Doing this will prompt you to enter the email address of the account you wish to sign-in with: You can use either a Microsoft Account (e.g. Windows Live ID) or an Organizational account (e.g. Active Directory) as the email.  The dialog will update with an appropriate login prompt depending on which type of email address you enter: Once you sign-in you’ll see the Windows Azure resources that you have permissions to manage show up automatically within the Visual Studio Server Explorer (and you can start using them): With this new integrated sign in experience you are now able to publish web apps, deploy VMs and cloud services, use Windows Azure diagnostics, and fully interact with your Windows Azure services within Visual Studio without the need for a management certificate.  All of the authentication is handled using the Windows Azure Active Directory associated with your Windows Azure account (details on this can be found in my earlier blog post). Integrating authentication this way end-to-end across the Service Management APIs + Dev Tools + Management Portal + PowerShell automation scripts enables a much more secure and flexible security model within Windows Azure, and makes it much more convenient to securely manage multiple developers + administrators working on a project.  It also allows organizations and enterprises to use the same authentication model that they use for their developers on-premises in the cloud.  It also ensures that employees who leave an organization immediately lose access to their company’s cloud based resources once their Active Directory account is suspended. Filtering/Subscription Management Once you login within Visual Studio, you can filter which Windows Azure subscriptions/regions are visible within the Server Explorer by right-clicking the “Filter Services” context menu within the Server Explorer.  You can also use the “Manage Subscriptions” context menu to mange your Windows Azure Subscriptions: Bringing up the “Manage Subscriptions” dialog allows you to see which accounts you are currently using, as well as which subscriptions are within them: The “Certificates” tab allows you to continue to import and use management certificates to manage Windows Azure resources as well.  We have not removed any functionality with today’s update – all of the existing scenarios that previously supported management certificates within Visual Studio continue to work just fine.  The new integrated sign-in support provided with today’s release is purely additive. Note: the SQL Database node and the Mobile Service node in Server Explorer do not support integrated sign-in at this time. Therefore, you will only see databases and mobile services under those nodes if you have a management certificate to authorize access to them.  We will enable them with integrated sign-in in a future update. Remote Debugging Cloud Resources within Visual Studio Today’s Windows Azure SDK 2.2 release adds support for remote debugging many types of Windows Azure resources. With live, remote debugging support from within Visual Studio, you are now able to have more visibility than ever before into how your code is operating live in Windows Azure.  Let’s walkthrough how to enable remote debugging for a Cloud Service: Remote Debugging of Cloud Services To enable remote debugging for your cloud service, select Debug as the Build Configuration on the Common Settings tab of your Cloud Service’s publish dialog wizard: Then click the Advanced Settings tab and check the Enable Remote Debugging for all roles checkbox: Once your cloud service is published and running live in the cloud, simply set a breakpoint in your local source code: Then use Visual Studio’s Server Explorer to select the Cloud Service instance deployed in the cloud, and then use the Attach Debugger context menu on the role or to a specific VM instance of it: Once the debugger attaches to the Cloud Service, and a breakpoint is hit, you’ll be able to use the rich debugging capabilities of Visual Studio to debug the cloud instance remotely, in real-time, and see exactly how your app is running in the cloud. Today’s remote debugging support is super powerful, and makes it much easier to develop and test applications for the cloud.  Support for remote debugging Cloud Services is available as of today, and we’ll also enable support for remote debugging Web Sites shortly. Firewall Management Support with SQL Databases By default we enable a security firewall around SQL Databases hosted within Windows Azure.  This ensures that only your application (or IP addresses you approve) can connect to them and helps make your infrastructure secure by default.  This is great for protection at runtime, but can sometimes be a pain at development time (since by default you can’t connect/manage the database remotely within Visual Studio if the security firewall blocks your instance of VS from connecting to it). One of the cool features we’ve added with today’s release is support that makes it easy to enable and configure the security firewall directly within Visual Studio.  Now with the SDK 2.2 release, when you try and connect to a SQL Database using the Visual Studio Server Explorer, and a firewall rule prevents access to the database from your machine, you will be prompted to add a firewall rule to enable access from your local IP address: You can simply click Add Firewall Rule and a new rule will be automatically added for you. In some cases, the logic to detect your local IP may not be sufficient (for example: you are behind a corporate firewall that uses a range of IP addresses) and you may need to set up a firewall rule for a range of IP addresses in order to gain access. The new Add Firewall Rule dialog also makes this easy to do.  Once connected you’ll be able to manage your SQL Database directly within the Visual Studio Server Explorer: This makes it much easier to work with databases in the cloud. Visual Studio 2013 RTM Virtual Machine Images Available for MSDN Subscribers Last week we released the General Availability Release of Visual Studio 2013 to the web.  This is an awesome release with a ton of new features. With today’s Windows Azure update we now have a set of pre-configured VM images of VS 2013 available within the Windows Azure Management Portal for use by MSDN customers.  This enables you to create a VM in the cloud with VS 2013 pre-installed on it in with only a few clicks: Windows Azure now provides the fastest and easiest way to get started doing development with Visual Studio 2013. Windows Azure Management Libraries for .NET (Preview) Having the ability to automate the creation, deployment, and tear down of resources is a key requirement for applications running in the cloud.  It also helps immensely when running dev/test scenarios and coded UI tests against pre-production environments. Today we are releasing a preview of a new set of Windows Azure Management Libraries for .NET.  These new libraries make it easy to automate tasks using any .NET language (e.g. C#, VB, F#, etc).  Previously this automation capability was only available through the Windows Azure PowerShell Cmdlets or to developers who were willing to write their own wrappers for the Windows Azure Service Management REST API. Modern .NET Developer Experience We’ve worked to design easy-to-understand .NET APIs that still map well to the underlying REST endpoints, making sure to use and expose the modern .NET functionality that developers expect today: Portable Class Library (PCL) support targeting applications built for any .NET Platform (no platform restriction) Shipped as a set of focused NuGet packages with minimal dependencies to simplify versioning Support async/await task based asynchrony (with easy sync overloads) Shared infrastructure for common error handling, tracing, configuration, HTTP pipeline manipulation, etc. Factored for easy testability and mocking Built on top of popular libraries like HttpClient and Json.NET Below is a list of a few of the management client classes that are shipping with today’s initial preview release: .NET Class Name Supports Operations for these Assets (and potentially more) ManagementClient Locations Credentials Subscriptions Certificates ComputeManagementClient Hosted Services Deployments Virtual Machines Virtual Machine Images & Disks StorageManagementClient Storage Accounts WebSiteManagementClient Web Sites Web Site Publish Profiles Usage Metrics Repositories VirtualNetworkManagementClient Networks Gateways Automating Creating a Virtual Machine using .NET Let’s walkthrough an example of how we can use the new Windows Azure Management Libraries for .NET to fully automate creating a Virtual Machine. I’m deliberately showing a scenario with a lot of custom options configured – including VHD image gallery enumeration, attaching data drives, network endpoints + firewall rules setup - to show off the full power and richness of what the new library provides. We’ll begin with some code that demonstrates how to enumerate through the built-in Windows images within the standard Windows Azure VM Gallery.  We’ll search for the first VM image that has the word “Windows” in it and use that as our base image to build the VM from.  We’ll then create a cloud service container in the West US region to host it within: We can then customize some options on it such as setting up a computer name, admin username/password, and hostname.  We’ll also open up a remote desktop (RDP) endpoint through its security firewall: We’ll then specify the VHD host and data drives that we want to mount on the Virtual Machine, and specify the size of the VM we want to run it in: Once everything has been set up the call to create the virtual machine is executed asynchronously In a few minutes we’ll then have a completely deployed VM running on Windows Azure with all of the settings (hard drives, VM size, machine name, username/password, network endpoints + firewall settings) fully configured and ready for us to use: Preview Availability via NuGet The Windows Azure Management Libraries for .NET are now available via NuGet. Because they are still in preview form, you’ll need to add the –IncludePrerelease switch when you go to retrieve the packages. The Package Manager Console screen shot below demonstrates how to get the entire set of libraries to manage your Windows Azure assets: You can also install them within your .NET projects by right clicking on the VS Solution Explorer and using the Manage NuGet Packages context menu command.  Make sure to select the “Include Prerelease” drop-down for them to show up, and then you can install the specific management libraries you need for your particular scenarios: Open Source License The new Windows Azure Management Libraries for .NET make it super easy to automate management operations within Windows Azure – whether they are for Virtual Machines, Cloud Services, Storage Accounts, Web Sites, and more.  Like the rest of the Windows Azure SDK, we are releasing the source code under an open source (Apache 2) license and it is hosted at https://github.com/WindowsAzure/azure-sdk-for-net/tree/master/libraries if you wish to contribute. PowerShell Enhancements and our New Script Center Today, we are also shipping Windows Azure PowerShell 0.7.0 (which is a separate download). You can find the full change log here. Here are some of the improvements provided with it: Windows Azure Active Directory authentication support Script Center providing many sample scripts to automate common tasks on Windows Azure New cmdlets for Media Services and SQL Database Script Center Windows Azure enables you to script and automate a lot of tasks using PowerShell.  People often ask for more pre-built samples of common scenarios so that they can use them to learn and tweak/customize. With this in mind, we are excited to introduce a new Script Center that we are launching for Windows Azure. You can learn about how to scripting with Windows Azure with a get started article. You can then find many sample scripts across different solutions, including infrastructure, data management, web, and more: All of the sample scripts are hosted on TechNet with links from the Windows Azure Script Center. Each script is complete with good code comments, detailed descriptions, and examples of usage. Summary Visual Studio 2013 and the Windows Azure SDK 2.2 make it easier than ever to get started developing rich cloud applications. Along with the Windows Azure Developer Center’s growing set of .NET developer resources to guide your development efforts, today’s Windows Azure SDK 2.2 release should make your development experience more enjoyable and efficient. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • "must be convertible to System.Web.UI.Page" using custom base page in Visual Studio 2010

    - by Payton Byrd
    I have a HUGE problem. We just converted our large project to a Visual Studio 2010 solution, but maintained .Net 3.5 targets. This seemed to go swimmingly, almost too easy. Today I just encountered a huge problem. When we add a new asp.net tag to a page the designer class is not being updated. I looked around and noticed that the type specified in the Page's Inherits attribute was underlined in red. Hovering over that gives the error "must be convertible to System.Web.UI.Page". Obviously the designer isn't casting the page correctly and it's because we are using a custom base page, just as we had been with no problems in VS 2008. Has anyone else encountered this problem? If so, what's the solution. This is a show-stopper for us to use VS 2010 (and lots of egg on our faces for moving to it in the first place).
