Error loading pipeline assembly TrueTypeImporter


When attempting to build a Windows Phone 7 game that uses Nuclex.Fonts I get
Error 1 Error loading pipeline assembly "Nuclex.Fonts.Content.TrueTypeImporter.dll".
I'm using VS2010.

Looks like the Windows Phone content pipeline cannot load nunit.framework.dll for some reason. I'll have a closer look to fix this before the next release. For now, I've compiled a binary of the TrueTypeImporter without the NUnit dependency (see project attached to this comment).

You do not need to add Nuclex.Fonts.dll, Nuclex.Graphics.dll or anything except Nuclex.Fonts.Content.TrueTypeImporter.dll to your content project.
It's also not a good idea to add Nuclex.Fonts.Content.TrueTypeImporter.dll to your game project (it's a Windows-only binary that's only required at compile time).
And there's no need to add the Nuclex DLLs to the project as files, adding them as references suffices for them to be deployed.

The messy project was a result of me trying everything to get it working. Out of interest, how did you debug this issue? I couldn't get any further information out of MSBuild

Thanks for the fix.

I had the same error. I fixed it by removing the unit test assembly reference from the truetypeimporter project and re-building.

I am having the same issue when I try and compile the demo application for the windows (x86) environment....

I had this issue as well. I have fixed it finally! The problem stems from the download being blocked when it is downloaded. I used the alternatestreamviewer link in the following post.

Did you forget to attache the project? The only attachments seem to be on the original post and have the Error loading pipeline assembly error.
