Test projects in Visual Studio 2010 must target .NET Framework 4.0. See this post for details. This issue may have been fixed in SP1.

I made a copy of an existing solution and put it in a different folder. When I tried to run it, I got the following error. Meta file ‘C:\MyProject\Some.dll’ could not be found.

There is no obvious way to specify the programming language as you create a new project. You are not able to change the default setting at the usual places such as Tools | Options… or the project’s properties. The most common solution, as suggested in various forums including the quasi-official Visual C# Forums , is to go to Tools | Import and Export Settings… and select Reset All Settings.

Even if you are lucky to guess it right, most people would be taken aback by Resetting All Settings. What settings it will
