Wrap function. Good way to have a generic exception handler.

Wrap.cs

private static void Wrap(Action func)
{
    try
    {
        func();
    }
    catch (DbEntityValidationException ex)
    {
        var error = ex.EntityValidationErrors.First().ValidationErrors.First();
        Debug.WriteLine(error.PropertyName + ": " + error.ErrorMessage);
        throw;
    }
    catch (Exception ex)
    {
        Debug.WriteLine("Error: " + ex);
    }
}
