When a stored procedure I’m running executes mini-profiler throws a null reference and causes my application to stop. In this instance the SP doesn’t return anything.
Here is the stacktrace:

I finally figured out the solution to my question above. The error was happening on a legacy webforms application that was using sql data source for the grid. The sql datasource was using the ‘ProviderName’ property. Once I removed this property everything started working.
