This is really basic question and may be duplicate. Can anyone tell me how useful error info generated by any program in .Net.

Today I got an error “Ambiguous match found.” while saving entity in database (using EF4)
I can’t figure out why this error is coming, what is the root cause. Attached is the snap for same.

    Hmya, no such luck. It would be very nice indeed if the Type.GetProperty() method would actually say which name was ambiguous. But it doesn’t and you cannot easily find out. The code lives in the .NET framework and it is optimized, the debugger cannot retrieve the value of the name argument. Your only cue is that your entity model has two properties with the same name. Something like that anyway.
