Okay.  Here's a overview of what I'm doing:
Installed NUnit 2.5.4.10098.
Created new Class Library in Visual Studio 2010 RTM.
Added nunit.framework.dll to references.
Added [TestFixture] to a class, added a [Test] method to a new method. Built.
Ran nunit.exe
Dragged compiled class library DLL onto Nunit runner.
NullReferenceException occured.  Detail from Tools\Exception Details

System.NullReferenceException...

I then clicked the File menu to exit, then got an unhandled exception:
See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.



If I run nunit-x64.exe and do the same steps I get the same results.

NUnit crashes on .NET 4.0 x64 assemblies

You received this bug notification because you are a member of NUnit

Status in NUnit V2 Test Framework: New

Bug description:
NUnit 2.5.4 shows an error (NullReferenceException) when attempting to test .NET 4.0 assemblies built for AnyCPU (= running as x64 on my system).  This is with the final release version of VS2010 on Vista 64, and affects both the GUI and the console runner.  Attempting to do anything else in the GUI runner then causes a follow-up exception.

To fix, I had to edit the files nunit.exe.config and nunit-console.exe.config, adding the following line after the <configuration>  tag in each file: <startup><requiredRuntime version="v4.0.30319" /></startup>

Peter Ritchie reports that .NET 4.0 assemblies do work if they were built for x86 and he used nunit-x86.exe, hence I assume that this problem is specific to x64 assemblies:
