I finally tried to solve the un-updatable .NET issue yesterday (KB928365 and KB928366). I went through the steps of removing .net and re-installing...
Today I got the dreaded "file not found microsoft.windows.commonlanguageruntime" error. The advice I found was to not reference another project in your solution, reference a file instead...
So I moved all forms and classes from referenced forms into the main project, removed references to the other projects and tried to recompile...
Holy C#@p!
Now ALL designers are throwing errors. They won't display anything but the error message. All the errors messages are pretty much the same: system.componentmodel.IContainer is ambiguous in the namespace system.componentmodel.
The errors seem to be for pretty much everything in the system.componentmodel namespace.
Please, Please, Please tell me this is fixable. I am completely lost.
