SYMPTOMS

On a computer that has Micrososft Visual Studio 2008 Service Pack 1 (SP1) installed, live semantic analysis incorrectly reports error messages when you perform one of the following actions:
  • You open a solution that contains breakpoints in the .aspx.cs files.

    Note If you double-click any error message or open the corresponding .aspx files, the error message disappears.
  • You run a project that uses a constant that requires a conversion. When this occurs, the error message resembles the following:
    The operation overflows at compile time in checked mode
    This problem may occur if your code contains the following code:
    class Program {
    
    static void Main(string[] args)
    {
        ulong x = ulong.MaxValue - 2;
    }
    
    }
    
  • You reference certain constructs that are defined in metadata. This issue occurs if the metadata is produced by a compiler other than the C# compiler.
