• Whats so bad about binding your View to Property of a Model and NOT ViewModel ??

  - by msfanboy

  Hello, I often hear a Model must be wrapped by a ViewModel that the View is not coupled to the Model/not aware of it. With MVC it is common to bind the View to the Model... nobody complains so what ? I am frightened of creating all that wrappers and doing nearly only duplicating property stuff.

• How to map a Entity Data Model conceptual model property to a storage model column using the "Serial

  - by codekaizen

  I have a conceptual model in EDM where one of the entities has a property which is essentially a big value object whose properties aren't really useful as columns in the datamodel. I'd like to apply the Serialized LOB pattern to it so that I can fit it into a 192 byte binary column. How do I map this in the EDM v4? Is it even possible at this time? Actually, is it possible in any ORM?

• What is a good naming convention to differentiate a class name from a property in C#?

  - by Andy Stampor

  I run into this frequently enough that I thought I'd see what others had to say about it. Using the StyleCop conventions, I find that I often have a property name that is hard to make different than the class name it is accessing. For example: public class ProjectManager { // Stuff here } public class OtherClass { private ProjectManager ProjectManager { get; set; } } It compiles and runs, but seems like it would be an easy way to confuse things, even with the use of "this".

• In Sharepoint, how do I update the name of a folder in a document library using the web service API?

  - by Jess

  I'm using the UpdateListItems method of the Lists web service, and I can update an item in just about any kind of list, and folders in non-document library lists, but I can't seem to update the name of a folder in a document library. I must use the web services API, as sharepoint is not local. If my update batch looks like this: <Batch OnError="Continue" PreCalc="TRUE" ListVersion="0" ViewName=""> <Method ID="1" Cmd="Update"> <Field Name="ID">2</Field> <Field Name="Title">MyUpdatedFolderName</Field> <Field Name="FileLeafRef">MyUpdatedFolderName</Field> </Method> </Batch> I get no exception but the name is unchanged. If my update batch looks like this: <Batch OnError="Continue" PreCalc="TRUE" ListVersion="0" ViewName=""> <Method ID="1" Cmd="Update"> <Field Name="ID">2</Field> <Field Name="Title">MyUpdatedFolderName</Field> <Field Name="BaseName">MyUpdatedFolderName</Field> </Method> </Batch> I get an error result that the list item could not be found. I know the list item is there. Anyone have any ideas?

• How to assign a value of a property to a var ONLY if the object isn't null

  - by Blankman

  In my code, is there a shorthand that I can use to assign a variable the value of a object's property ONLY if the object isn't null? string username = SomeUserObject.Username; // fails if null I know I can do a check like if(SomeUserObject != null) but I think I saw a shorthand for this kind of test. I tried: string username = SomeUserObject ?? "" : SomeUserObject.Username; But that doesn't work.

• How can I locate .NET Library property/function that return a particular type?

  - by Michael Bray

  Occasionally I will know that there is a .NET Framework function that returns a particular type of object, but I can't recall the property or function name. It would be really nice to be able to somehow scan the Framework or other DLL for functions that return a particular type of object. (For example, it would have helped when I asked this question, and I have a similar question again.) Can anyone suggest how I might do this?
