*BUG Report* This might be a bug more on Microsoft's side but I thought I would make you aware of it.
Description: If a user adds a solution to Subversion using Visual SVN from Visual Studio 2008 and then tries to open the solution AND/OR any of the projects in the subfolders of the solution directory Expression Blend will fail to open said solutions or projects. This is because of two things. First, Visual SVN makes a modification to the .sln file adding it's Extensibility section, normally this wouldn't cause any problems HOWEVER when you combine it with the second issue, which is that when Expression Blend (2.0) tries to open the .sln it fails silently. To make matters worse apparently when Expression Blend even tries to open a .csproj file for example in one of the subdirectories of the solution i.e. (SolutionDirectoryName\ProjectDirectory) it has some built mechanism to check for a .sln file in the parent directory of the project directory thus trying to read the .sln file instead of the .csproj and failing silently again. My fix was to not use Visual SVN any more until this is fixed and manually add my code to my repositories using Tortoise. This bug is especially irritating because Blend 2 will not provide any exception information and fails completely silently as if you never even tried to open the file.
