Remove Assembly that was loaded with addAssembly

How do I remove an assembly that was loaded with addAssembly?

Situation: I installed an assembly in the GAC and loaded it into MATLAB. now im doing some integration tests with the same dll but loaded from a different place in the file system and MATLAB is giving me a warning and i cannot step into the dll source.

CODE:

NET.addAssembly('C:\foo\foo.dll');

Warning: Assembly C:\Windows\Microsoft.Net\assembly\GAC_MSIL\foo\v4.0_1.0.0.0__772795e52c232a80\foo.dll' has already been added from location 'foo'

How do i get fix this? I have already removed dll from GAC

The documentation says you cannot unload. I end up restarting matlab each time.

Can I just ignore this warning?

[Hossam Alzomor]

you can asign the result of add assembly to variable and check for it before adding the assembly

if isempty(which('asm'))
    asm = NET.addAssembly('C:\foo\foo.dll');
end

I still get the following error when I add the isempty call

Warning: Assembly 'xx' has already been added from location 'C:\Users\yy\zz.dll'.

because

isempty(which('asm'))

is true.
