Public bug reported:
NUnit version 2.5.7.10213, GUI runner
Visual Studio 2010 Pro, no plugins
In a Visual Studio solution with 3 projects, NUnit sometimes crashes in
the background while source code changes are being made. The attached
zip is a trimmed down SampleApp solution that you can use to reproduce
the issue.
Steps to reproduce:
o VS2010 -> Load SampleApp solution.
o NUnit -> Load SampleApp.nunit.
o NUnit -> Run all tests to ensure they pass.
o VS2010 -> Do the following steps to cause NUnit to crash with an
unhandled exception.
o SampleApp project -> Actuator.cs -> change Actuate method signature
from:
void Actuate();
to:
void Actuate(int timesToActuate);
o F6 to build. This results in one build error as expected.
o SampleApp project -> Client.cs -> change statement in Actuate method
from:
actuator.Actuate();
to:
actuator.Actuate(timesToActuate);
o F6 to build. This results in another build error, and NUnit
crashes.
+ NUnit crash message:
Title: "Assembly Not Loaded"
Message: "System.TypeLoadException : Method 'Actuate' in type
'SampleApp.Mocks.MockActuator' from assembly
'SampleApp.Mocks, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null' does not have an implementation.
For further information, use the Exception Details menu item."
+ NUnit Exception Details shows this additional info:

o NUnit -> at this point opening the File menu or closing NUnit displays:

Continue, the application will ignore this error and attempt to continue.
If you click Quit, the application will close immediately.
No connection could be made because the target machine actively
refused it 127.0.0.1:49900."
o Running NUnit again without fixing the source code gets the same errors.
o Changing Client.cs first and then Actuator.cs gets the same errors.
+ In all these cases MockActuatorTests.cs and MockActuator.cs are left
unchanged. They must be changed also (or first) in order to resolve
or avoid the issue.
Let me know if I can provide additional information.
