                    hi all,
today when i tried to open an existing solution i had this message: 
"Project could not be opened because the Microsoft Visual C# .NET compiler could not be created. A wrapper assembly is not registered for this type library"
one time also appeared:
"Project could not be opened because the Microsoft Visual C# .NET compiler could not be created. Please re-install Visual Studio"
Any solution??? I worked whit this solution until yesterday with no problem. Now i can't open any solution or project. Thakns
