Yes, I did something similar as my first attempt, removing the static
constructor as well and adding a PreserveStackTrace method that uses
lazy initialization. The problem is twofold: (1) Mono doesn't have the
PerserveStackTrace method and (2) there's no reason to be messing
around with AsyncInvocationRegion in this example anyway, since no
async methods are involved.

The trouble is that IsAsyncOperation is a static method of
AsyncInvocationRegion and calling it triggers the static constructor.
Either that method has to be in another class or we need to do away
with all the static initialization. I did the latter.

I'm testing on Windows right now, by using the Gui runner to run the
NUnit tests under Mono. Before my fix, the tests would not even load.
With it they load but I'm getting some errors. I may need to move to a
Linux system to really  get into this.

Title:
  Proposed 2.6.3 release: ArgumentNullException in
  NUnit.Framework.AsyncInvocationRegion..cctor

Status in NUnit V2 Test Framework:
  New

Bug description:
  I've built and run the tests of XMLUnit's trunk against the proposed
  2.6.3 release assembly, all tests pass with 2.6.2.

  At least on Mono (2.10) on Linux I now see an ArgumentNullException -
  haven't tried any other environment.

  The test's code is
  https://sourceforge.net/p/xmlunit/code/HEAD/tree/trunk/xmlunit/src/tests
  /net-constraints/ValidationConstraintsTest.cs

  Error stack trace (copy pasting from an xterm):

     [nunit2] Test Case Failures:
