visual studio .net debugging: I have an application that I have been working on for 2 years in VB .NET and just recently, This particular application has been crashing the VS .NET IDE. Other applications seem to compile/link/debug just fine. However, this one application generates the following error messages after a "Build Solution" command

JIT debugging failed with the following error: Class not registered. Please check documentation 'Just in time debugging error' for more information(This is followed by the closure and automatic restart of the IDE

Sometimes I get an intermittant VS .NET IDE crash after a Debug(Start)

An exception 'System.NullReferenceException' has occurred in DefaultMain

O

The following exception has occurred: NullReference: Object Reference not set to an instance of an objec

Either of these is followed by a crash of the VS .NET ID

The problem is intermittant but frequent. I assume it must be something about the particular solution and not the IDE. It uses only the native .NET controls, Crystal Reports .NET or Syncfusion .NET 1.6.1.8 Essential Grid( In fact, if you remove the Essential Grid and its references, the errors still occur

I'm not sure where to start but I really need to fix this. Hel

There are two issues here. One, the application is causing Visual Studio to
crash and two, when VS crashes, JIT debugging fails. To start with, can you
look at the Event Viewer and see whether VS logged an event?

Yes the event viewer does log events similar to the three that I have included. Not sure what to do next. Clearly, this only occurs with one application(I have successfully compiled/linked/debugged other apps). I also seem to see a pattern that it occrs after the "Preparing Resources" statement appears in the output window after I click Build All. Finally, I occasionally get the following error : The following exception has occurred SEHException: External Component has thrown exception

Hope you can help me

Is this a large VB project? If so, does the following KB apply?

I've never seen a specific error "Stack Overflow". However, it is a large project, and it does quit intermittantly as described. I went to the referenced article but there is nowhere to download the hotfix. How would I do it
