unable to load Assembly

Question

I'm getting a strange error from my VisualStudio 2008 installation in Windows 7 and I wonder whether anyone knows how to fix that:

Unable to read the project file "cs.proj". Could not load file or assembly Microsoft.Build.Engine, Version=3.5.0.0, Culture=neutral, [...] System cannot find the file specified. `

I checked: .Net 3.5 is installed. So does anyone know what that means?

Thanks ;)

Answer 1

Try running gacutil -l to check if the MSBuild assemblies are installed

Answer 2

I found a thread on social.msdn.microsoft.com, http://social.msdn.microsoft.com/Forums/en/vssetup/thread/59fa45ee-ac51-4325-83fa-26389a33c22f

Iе offers that the .NET install might be corrupted and suggests uninstall .NET and do a full 3.5 SP1 install.

My IT department did a windows update and it interrupted my VS install with the "MSBuild assembly not found", and I have to wait for them to fix it because I don't have install rights.

Let me know if this works.
