Interop.ShDocVw.dll generates System.BadImageFormatException on my development machine!

[QuietLeni]

I am trying to build a strong-named DLL for use on a Windows 2008 R2 server (x64, of course) using Visual Studio 2010 Express on a Windows 7 SP1 64 development PC and I am having considerable issues with this. The DLL needs to be developed against .NET Framework 3.5.

Everything seemed to be OK when I was just working without strong-naming, but the strong-naming seems to cause issues when I move the DLL to the 2008 R2 Server.

I have done quite a bit of research about this and have created a simple demo Company.Test.DLL and this is now not working on my Development machine, either. The assembly is strong-named against a standard certificate I made.

The Company.Test.DLL uses c:\Windows\System32\ShDocVw.dll (I assume this is 64-bit?) and therefore, I added it in as a Reference for the Company.Test.DLL (so it generated the Interop.ShDocVw.dll) and added a simple method for opening Internet Explorer, navigate to a URL and then shut it down. The DLL is built for the "Any CPU" platform.

Now, I have created a test harness (also strong-named), built for the "Any CPU" platform and have referenced the Company.Test.DLL. Now, when running in Debug and I call the DoStuff method, I get the following error:


System.BadImageFormatException was unhandled

I am trying to work out what is going wrong.

All can I think is that the Interop DLL is referencing the wrong version (32-bit, not 64-bit) of the ShDocVw.DLL when it comes to running the Test application. I have tried copying the ShDocVw.DLL into the same directory as the bin directory, but I know that that is not going to be right.


Help, please?



Why cant Microsoft STOP developing software and START fixing software?
