NullReferenceException with Assert.That and NunitLite - nunit

Question

I'm using NunitLite for my unit testing for a Xamarin project.
Environment:
Windows 8.1 64 bit
Visual Studio 2012
Test project class library referencing .NET 4.5
NunitLite V1.0.0 package from NuGet - contains a build for .NET 4.5
Running tests using Nunit Test Adapter V1.2 from NuGet
With even the simplest test:
[Test]
public void SimpleTest()
{
Assert.That(1 == 1);
}
I'm getting the exception:
System.NullReferenceException was unhandled by user code
HResult=-2147467261 Message=Object reference not set to an instance
of an object. Source=nunitlite StackTrace:
at NUnit.Framework.Assert.IncrementAssertCount()
at NUnit.Framework.Assert.That(Object actual, IResolveConstraint expression, String message, Object[] args)

at SportLogger.Tests.Unit.Core.when_using_venue_manager.SimpleTest() in
c:\SportLogger\SportLogger.Tests.Unit.Core\CoreTests.cs:line 65 InnerException:
Does anyone have any pointers as to what the problem is?

Answer 1

I solved this by using standard Nunit, not NunitLite. I'm not sure why NunitLite doesn't work in a standard Windows test library.
Bearing in mind that NunitLite is meant to be used (in this context) on the iOS and Android projects, switching to Nunit for the core test project, and NunitLite for the iOS and Android test projects fixed the problem.
