ExecuteNonQuery with StoredProcedure throwing Error

[Former Member]

Are there any known issues when using the EnityConnection and doing a storedprocedure call with an ExectueNonQuery()? This call is always throwing an 'Object reference not set to an instance of an object'. But looking at the stack the error happens on a System.Data.EntityClientEntityDataReader.Close(). I'm wondering if it is a bug since two steps earlier in the stack it issued a System.Data.EntityClient.EntityDataReader.Dispose(). When walking through the code in debug the error is thrown inside the ExecuteNonQuery() call. However, the code in the stored procedure is executed. As a work around I have put a try/catch around the ExecuteNonQuery() call. I am using Visual Studio 2008 and the 3.5 framework, connecting to Sybase 12.0 using iAnywhere.Data.SQLAnywhere.

What happens, if you use the executenonquery for any other call not involving the stored procedure?

Please show the code, and the full error stack.

Try asking a specific question like "How do I fix this exact problem?"... it might get an answer, whereas open-ended non-specific questions like "Are there any known issues?" will never get an answer.
