Question

I have a Guid.NewGuid() call that is creating an Empty Guid.

What would cause such a problem and how can I fix it?

Edit: The code:

<WebMethod()> _ Public Function CreateRow(rowValue As String) as String     Dim rowPointer As Guid = System.Guid.NewGuid()     Dim rowPointerValue As String = rowPointer.ToString()      Try         Dim result as Integer = SqlHelper.ExecuteNonQuery(ConnectionString, 'Sproc_Name', rowValue, rowPointer)          Return result     Catch ex as Exception         Throw ex     End Try End Function 

Edit: Turns out that rowPointer was originally being passed to the SqlHelper and not rowPointerValue – This of course is passed as empty, as pointed out in the answers. Changing it to rowPointerValue/rowPointer.ToString() fixed the problem.

This is an old problem in VB.NET. It is only the debug visualizer that is broken.
