I am trying to run my tests with the latest build of everything (including NUnit 2.2.8) The problem I am having is NUnit-gui.exe will not start with mocking_on. If I run mocking_off it runs fine (but the tests fail because mocking is off). Run mocking_on and the GUI does not start (I see it in TaskManager, but it just disappears).

Same thing happens with mocking off and using TMockRunner.

In the application event log I see 436 of this:

.NET Runtime version 2.0.50727.42 - Fatal Execution Engine Error (7A05E2B3) (80131506)

For more information, see Help and Support Center at

Of course clicking on the link gives me this from Microsoft:
We're sorry 
There is no additional information about this issue in the Error and Event Log Messages or Knowledge Base databases at this time. You can use the links in the Support area to determine whether any additional information might be available elsewhere. 

Any thoughts?

I have looked into this some more and found that is it not a problem with NUnit but with NCover. If I unlink NCover then NUnit will run fine with mocking on.

I have tried NCover version 1.5.2, 1.5.3, and 1.5.4.

Also, I can't seem to find the typemock log file.

To use TypeMock with NCover use the following steps:
1. Link TypeMock to NCover. This can be done in two ways:
Use TypeMock configuration GUI:
Open TypeMock Configuration. Start -> Programs -> TypeMock.NET -> TypeMock Configuration.
Go to the profilers tab.
Select NCover from the drop down list and click "Link with TypeMock" button.
Or you can use TMockRunner.exe comand line tool.
TMockRunner has a -link argument for this.
For example to run NCover with NUnit and TypeMock:
tmockRunner -link NCover nunit-console.exe test.dll

2. Do not run mocking_on.bat

3. Run your test through NCover.

Hope it helps. Please tell me if it solves your problem.

I am experiencing the same problem. Whenever TypeMock links with NCover the process (either nunit-gui or nunit-console) bombs out early. Without linking to NCover it runs successfully.

I am using ncover, nunit, and typemock

The command I am using is:

TMockRunner -link NCover -loglevel 9 nunit-console unittests.dll

The output of the logs is short and sweet so I'll post it all here.

First up is "TypeMock-nunit-console.exe-1.12.2006-9-49-22.out"
