Could not load file or assembly Interop.SHDocVw

Install watin by Nuget today but can't run correctly and show this Popup.

After some research it easy to fix by change "Embed Interop Type" to False (Default value is True) in Properties windows.

Now can run without problem.

NUnit 2.5.5 and .NET 4 Testing

I have problem to load assembly .NET 4 to test
Yes compile to .NET 2 will don't have any problem but .NET 4 I can't open dll to test

To fix this we need to modified nunit.exe.config
In folder nunit.exe we used

by 2 step

1. Under <configuration> add:
<startup><requiredRuntime version="v4.0.30319" /></startup>
2. Under <runtime> add:
<loadFromRemoteSources enabled="true" />

Yes for me .NET is version 4.0.30319 (for now)
