Report Services crashes in visual studio debugger for local report when page number parameters are added

Question

I have a report that looks like this:

There isn't anything really special about the report, it's my first report I've made with reporting services for my application (we're transitioning from crystal reports).

It's a local report that runs fine outside of visual studio. However, if I run it inside visual studio with that bottom right corner textbox (the expression is =Globals.PageNumber & " of " & Globals.TotalPages ) it crashes. If I remove the box, it runs.

It crashes with this error code:

The assembly with display name 'expression_host_9191d5a6e4724724b792f551d1c7a8e9' failed to load in the 'LoadFrom' binding context of the AppDomain with ID 1. The cause of the failure was: System.IO.FileNotFoundException: Could not load file or assembly 'expression_host_9191d5a6e4724724b792f551d1c7a8e9, Version=11.2.30319.1, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

Does anyone know what I'm doing wrong?

This is a bit of a shot in the dark but my next move would be to disable the Visual Studio hosting process.

• Right Click on project and select Properties
• Go to the Debug Tab
• Uncheck "Enable the Visual Studio hosting process"

It's possible this particular project type doesn't support the hosting process in which case it will be grayed out (and I'll be wrong :) ).
