Windows Phone 7 XImporters, TextureImporters error

I wanted to run some of my old XNA projects which gave me a cryptic error message XImporters or TextureImporters missing. When I looked in my references these assemblies where there and properly referenced.

Then I came across this blog Assembly references in XNA Game Studio 4.0 beta projects need to be updated after installing the final release by Aaron Stebner.

As per Aaron’s recommendation I removed all references to the Microsoft.Xna.Framework.Content.Pipeline assemblies and added them again. It worked.

The assemblies are in the following folder: C:\Program Files\Microsoft XNA\XNA Game Studio\v4.0\References\Windows\x86\

The offending assemblies in my project were:

Microsoft.Xna.Framework.Content.Pipeline.AudioImporters
Microsoft.Xna.Framework.Content.Pipeline.EffectImporters
Microsoft.Xna.Framework.Content.Pipeline.FBXImporters
Microsoft.Xna.Framework.Content.Pipeline.TextureImporters
Microsoft.Xna.Framework.Content.Pipeline.VideoImporters
Microsoft.Xna.Framework.Content.Pipeline.XImporters
