Hi,

I'm evaluating NCrunch for a number of F# projects I am working on. I've let NCrunch work over a small solution and it builds a number of the dlls successfully but for a small number they fail to build with the following exception

[17:04:14.1933-LocalBuildTask-34] ERROR (Internal): System.ArgumentException: An item with the same key has already been added.
at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)

at nCrunch.Client.Processing.ProcessingQueue.#=q_vyIzYQsi20eEpIpxNwCkQ==(LocalProcessingTask #=ql59clHcEc0_22CWMfMeExQ==)

It's not immediately obvious to me what might be wrong - the same projects all build fine in Visual Studio (I'm using VS2010) and via MSBuild.

Any idea how I can get more information / debug output on the underlying problem so I can try and work out how I need to tweak my project?

Thanks!

Hi Adam,

Thanks for reporting this issue. It looks like the NCrunch build is reporting some kind of reference duplication in its output. Probably this is related to a library or toolset used by some of your projects.

Would you be able to submit a bug report straight after NCrunch has tried to build one of these failing projects? Hopefully the log file in the report will give us some more information.


Cheers,

Remco

Hi Remco,

Thanks for the quick reply - I've just restarted VS, let NCrunch start processing my solution and then as soon as the first project has errored in this way I've submitted a bug report via the NCrunch menu. Hopefully this will provide some more information about what is wrong.

Cheers

Thanks Adam. Unfortunately the log didn't show which reference was the direct cause of the problem, but I think this is an issue best solved by making NCrunch more resilient to this kind of build behaviour.

I'd like to provide you with a fixed build. If all goes well, hopefully I can get this to you tomorrow.

Sounds good - very happy to try out an experimental build when you have one.

Cheers

Hi Remco,

Unfortunately I can't access any of the links - I get 'Access Denied' (I've tried from a few environments / platform / work & home and it's the same result). I've logged in/out of the NCrunch site but it made no difference.

Cheers

Adam

Sorry, this was my mistake. I forgot to make the links public. Try again now.

Hi - I've downloaded and installed and my solution is now successfully 'crunched' with no errors (or changes needed on my side) - initial thoughts are very positive. Thank you!
