Error before running tests: FileNotFoundException / Dimebrain

I'm getting an unhandled exception when trying to run any of my Silverlight unit tests from ReSharper.

Message: Could not load file or assembly 'Dimebrain.Web.Silverlight.Serialization, Version=, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

I'm using Resharper 5.1 and am using version ... Any guidance would be greatly appreciated.

Hi Brian,

Can you make sure your test project has a reference to your "Dimebrain.Web.Silverlight.Serialization" project/assembly.
Also make sure "Copy Local" is set to TRUE, this way it's included in the .xap file.

Let me know if you still encounter issues.

I can't find the Dimebrain.Web.Silverlight.Serialization assembly anywhere.  Is it supposed to come bundled with AgUnit, ReSharper, or something else?

I have never heard of it, I guess it's something your project is referencing (maybe indirectly through a library ?).

Googling on "Dimebrain" reveals "Dimebrain.Tweetsharp". Are you using that in your project ?

The only external assembly i'm using is Moq.  The only thing I can think of is if something got registered in the GAC that's causing me issues.  I can probably take it from here, but thanks for looking.

You can try opening up the .xap file or your test project with a zip tool (7-zip, winrar, ...) and see which files are included. That might give you a clue.
Reflector can also help you out with finding hidden references.

Yeah, it was referenced by SharpLibZip which we are using for something else.  It wasn't being used, but it looks like when the assembly was loaded, it tried loading all referenced assemblies anyway.  We just abstracted out that part so that it got injected at runtime.
