Today I tried to open one of my Visual Studio 2010 Express Edition projects and was unable to open it. I thought that maybe the file is damaged or something like that, but it turns out that all my projects do this, including those that I have not touched for several months! This is the error message I get:
D:\CSharp\Sandbox\MustardApplication1\MustardApplication1\MustardApplication1.csproj : error : Unable to read the project file 'MustardApplication1.csproj'.
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(1693,24): The project file could not be loaded. '', hexadecimal value 0x0C, is an invalid character. Line 1693, position 24.
I have no idea what this is talking about, and I don’t know what to do next. I can’t even create a new “Windows Forms application”; I get the same error message. Can anyone help me out?
