I've had a little search and I was wondering if there is back compatibility for the .NET framework. The real question is, if there's a program that uses .NET Framework 1.1, can I install 3.5 and be done, or do I have to install 1.1 and then if something uses 3.5 I have to install 3.5 as well? ...

What are some important practices to follow when creating a .NET assembly that is going to be embedded to SQL Server 2005? I am brand new to this, and I've found that there are significant method attributes like: [SqlFunction(FillRowMethodName = "FillRow", TableDefinition = "letter nchar(1)")] I'm also looking for common pitfalls to a...

When you use Visual Studio's code analysic (FxCop), and want to supress a message there are 3 options. Supress a violation in code. Supress a violation in a GlobalSupression.cs file.

Here is the code that creates the FileSystemWatch...
