Rebuilding wServer

I want to recompile wServer so I opened wServer.csproj in Microsoft Visual Studio 2008 then I got this message:

And if I click OK it just doesn't open it.

Open the main project in the main private server folder, not just the wserver project. Opening this main solution will allow you to edit everything easily as well.

You should also update to Visual C# 2010.

Updated and now it works
