[Nant-users] Nant NUnit and remoting problem

[Henk van Jaarsveld]

Hi all,

 

Has somebody encountered this problem:

Step 1:

I have a NUnit test that does remoting. Running the test stand-allone (No NUnit, No nant) works fine.

 

Step 2:

Then I used NUnit and I got:

Exception: System.InvalidCastException
Message:
Return argument has an invalid type.
Stack trace:
   at System.Runtime.Remoting.Proxies.RealProxy.ValidateReturnArg(Object arg, Ty
pe paramType)

 

Diagnosis: NUnit did not load the assemblies referred by the test dll and therefor did not know some type that was to returned by the remote proces.

Solution: Explicitly load assemblies with Assembly.Load(---) in the test.

Result: It worked again.

 

Step 3:

I run the modified test from nant and I get the same exception again. The assembly loading is done explicitly but still the types are not known.

Solution after trial and error: Put a copy of assemblies in the bin directory of nant and it works again.

 

 

Does someone understand why it did not work in the first place from nant? And why putting a copy of the assemblies in the nant bin makes a difference? And is there a more elegant way to solve this problem?

 

Regards,

Henk
