The SET NOCOUNT issue is an unrelated issue to yours (judging by your
descriptions in other posts) that can cause a result that would make many
people think that a precedure was running twice, or that an extra procedure
was being executed.

I've never experienced a problem in ADO.Net similar to what you're
describing. My guess would be that you're doing two things in your .Net
code, each of which is causing the command to be executed, resulting in the
duplicate executions.
