NCrunch cannot discover tests due to serialization issues

Steps to reproduce:
1. Checkout the AutoFixture repo: https://github.com/AutoFixture/AutoFixture
2. Open the Src/AutoFixture.sln project.
3. Try to discover all the tests.

Result:
Discovery fails for .NET Core App framework. Here are examples of errors:

An error occurred while analysing this project after it was built: System.Exception: Error while discovering test 'AutoFixtureUnitTest.RandomRangedNumberGeneratorTest.CreationOnFullRangeShouldntFail("System.SByte", "-128", "127")':System.Runtime.Serialization.SerializationException: Unknown primitive type: System.SByte

Error while discovering test 'AutoFixtureUnitTest.Kernel.MultidimensionalArrayRelayTest.Create3DimensionalArrayReturnsCorrectResult([[["12"]]], ["12"])':System.Runtime.Serialization.SerializationException: Cannot find serialization contract for type: System.Int32[][]

Expected result:
Discovery should pass successfully.

Notes:
For history: current SHA1 of the master is c7a27680155bcaf22dc1f6e6d62f14cc8614217c.

It seems you cannot serialize SByte and multi-dimensional arrays.

Thank you!

Hi, thanks for sharing this problem.

It looks like we are missing a type in our binary serializer. From what I can determine, this will affect .NET Core projects (not .NET Framework ones).

I'll make sure this gets fixed in the next release. Thanks for bringing it to my attention!

Thank for your the confirmation! Will be nice to have it working ;-)

P.S. Thank you for the great product you are making. It totally changed my coding experience and now it's hard to imagine my life without this tool.

Thank you for your efforts on AutoFixture! :)
