I have a project which uses workflow and dynamic assemblies. When the project is being debuged in Visual Studio 2005 the "A first chance exception of type 'System.NotSupportedException' occurred in mscorlib.dll" is thrown.
Call stack:

How I can solve this problem

Problem with dynamic assemblies usage
EdZilla
Hi, Sonali!
1. Steps for reproduce:
- Create Sequential Workflow Console Application
- In Main function before creating WorkflowRuntime (code created by wizard) insert:
AppDomain
myAppDomain = Thread.GetDomain(); AssemblyName myAsmName = new AssemblyName();myAsmName.Name =
"MyAssembly"; AssemblyBuilder myAsmBuilder = myAppDomain.DefineDynamicAssembly( myAsmName, AssemblyBuilderAccess.Run); ModuleBuilder myModuleBuilder = myAsmBuilder.DefineDynamicModule("MyModule1");- Check on "Debug->Exceptions->Common Language Runtime Exceptions"
- Press F5
2. I'm debugging using F5
3. I have created Sequential Workflow Console Application. Workflow and host are in the same application.
4,5. Debug engine starts automaticaly.
6. I'm use default debugging options:
"Debugging->Workflow->Enable native code debugging" is turned off,
"Debugging->Just-In-Time->Native" is turned on,
"Debugging->Just-In-Time->Workflow" is turned off,
"Debugging->Native->Load DLL exports" is turned off,
"Debugging->Native->Enable RPC debugging" is turned off
7. -MS VS 2005 Proffesional Edition Version 8.0.50727.42 (RTM.50727.4200 )
- MS .NET Framework Version 2.0.50727
- WF beta 2 (Version of assemlies 3.0.0.0)
Thanks,
Nata

Hi Nata,
Thanks for the repro steps. We were able to repro the problem and we are investigating this issue. In beta2 there is no functionality to disable the debugger but we have added it in our RTM release version.
Thanks,

Hi Nata,
Can you give us some more details about your scenario
1. What assemblies are dynamic and how are you using them in the workflow
2. Are you debugging the workflow using F5 or Attach to process
3. Is workflow and host separate or in the same application
4. If you are debugging using Attach to process, is debug engine selection automatic or manual
5. If manual, are you selecting any other debug engines along with the Workflow
6. Have you enabled Native code debugging
7. What is the version of VS and WF
Thanks,
Sonali
