This error occurs seemingly at random when running my project in Debug config. There''s no source-code for the excepting location, despite the fact that I''m compiling my test project against project-references to Grid, Grid.Grouping, Grouping and Shared. Interestingly, the debug output suggests that the .NET runtime is loading syncfusion DLLs from the GAC; I don''t understand this because my solution contains the syncfusion projects and my test app contains project references, not GAC references.

Some more detailed dbg output for this fault, from running without the debugger: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

Can you submit a Direct Trac support incident and request the latest private build to see if you still get this exception in that build?
