Unable to load type System.Collections.Generic.Dictionary

Question

When I am staring my VS-2005 it is throwing this error:
System.Runtime.Serialization.SerializationException: Unable to load type System.Collections.Generic.Dictionary`2[[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Collections.Generic.List`1[[Microsoft.Practices.RecipeFramework.VisualStudio.ToolWindow.GuidanceNavigatorManager+RecipeExecutionHistory, Microsoft.Practices.RecipeFramework.VisualStudio, Version=1.0.60429.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a]], mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]] required for deserialization.

Hi,

Next to your solution file, you should have a .gpState file, try to remove it. That should fix the issue. The gpstate file is a hidden file, so you probably won't see the file is you don't have see hidden files active.

hth.
