WatiN System.IO.FileNotFoundException Interop.SHDocVw

Question

I have just started to receive the following error when running my WatIn tests.

System.IO.FileNotFoundException : Could not load file or assembly 'Interop.SHDocVw, Version=1.1.0.0, Culture=neutral, PublicKeyToken=db7cfd3acb5ad44e' or one of its dependencies. The system cannot find the file specified.

I have searched the web and tried the following solutions, none of which work.

• WatiN Error Could not Load Assembly

Can anyone assist?

Answer 1

I always end up recompiling watin so it isn't signed, as I couldn't make any of the suggested solutions work either.

You can get the source here: http://watin.org/

Open the solution in the \source\src folder (there are VS2008 and VS2010 versions), open both projects and go properties -> Signing, uncheck 'sign the assembly', and build the solution.

You should get two DLLs in \source\src\Core\bin (WatiN.Core.dll and Interop.SHDocVw.dll) - just copy these into your project and they should work Ok.
