I could be missing something really straightforward here but I cannot for the life of me get an nUnit project to build in XS on Mac. Creating the same project on XS in Windows is not a problem - only on the Mac (which is running Alpha updates for the University courses).
It started when I downloaded companion code for a Xamarin book and tried to build it - the test project failed to build. After a lot of faffing about I created a new, blank, iOS app and added a new nUnit project to it with a single test:
Assert.That(1, Is.Not.Negative);
Which I think we all agree should pass - and it did .... the first time!
After closing the solution and reopening it I now get the same error as with the book code
'The name 'Is' does not exist in the current context'
Going through the same process in XS on Windows has no issues.
Can someone please save my sanity - is this a side effect of running the Alpha channel, am I missing something obvious or is there a more subtle problem?
Thanks in advance/
