Hi,

I am starting a new cross platfom project using Xamarin.Forms.
I am putting my shared code into a "Portable" Class library.
I am using xUnit for unit testing.
My first unit test - <class> can be created - works nice using ReSharper or MS-Test.

As I try to run the tests with NCrunch I get the following Build-Error-Message:
NCrunch: If you are experiencing problems in getting this project to build, have a look at http://www.ncrunch.net/d...ng_project-build-issues
..\packages\Xamarin.Forms.1.4.3.6358-pre2\build\portable-win+net45+wp80+win81+wpa81+MonoAndroid10+MonoTouch10+Xamarin.iOS10\Xamarin.Forms.targets (56, 3): Unerwarteter Fehler bei der XamlCTask-Aufgabe.
System.IO.FileNotFoundException: Die Datei oder Assembly "Xamarin.Forms.Xaml, Version=1.4.0.0, Culture=neutral, PublicKeyToken=null" oder eine Abhängigkeit davon wurde nicht gefunden. Das System kann die angegebene Datei nicht finden.

What is it I have to do, to get this test to run with NCrunch as well?

Thanks for any help!
Regards
Rainer

Hi Rainer,

This looks like an implicit reference to a build library inside the Xamarin package. See here for more information about this and how to fix it - http://www.ncrunch.net/documentation/considerations-and-constraints_implicit-file-dependencies.

Assuming you can solve the above problem, I'm afraid that I cannot guarantee that NCrunch will be able to work at all with this project. Xamarin is not supported by NCrunch at the moment.

Hi Remco,

thanks for the link. I at least was able to get my current tests running with NCrunch.
NCrunch is still complaining that it can't build one Project. I placed the error message below.

Rainer

Sorry, I'm afraid I can't provide a solution for this problem.

This appears to be caused by a clash between the Xamarin build and NCrunch's instrumentation. As far as I know, the only way to solve this would be to actually introduce proper support for Xamarin in NCrunch.
