Question

I’m using EF 4.1. Whenever an error occurs during the execution of a DbContext operation like SaveChanges() I consistently receive a rather cryptic error message: System.Exception._ComPlusExceptionCode -532462766. Obviously this is not very helpful for finding out what went wrong. A quick Google search for ComPlusException in context with EF returned no meaningful results.

Any ideas why I receive this error message and what can be done in order to get a more descriptive error feedback would be much appreciated.

Thanks!!

Code:

    public void InsertTarget(Target target)
    {
        try
        {
            _tgrContext.Targets.Add(target);
            _tgrContext.SaveChanges();
        }
        catch (Exception)
        {
            throw;
        }
    }

Found the answer to the problem here:

complusexceptions in net

In short: Visual Studio decodes the complusexception code into the actual error message on click at the red error quation mark in the VS code editor. I hardly ever use this visual indicatior, so I guess it was easy to miss for me.
