Could not load file or assembly 'msshrtmi' or one of its dependencies

Today, for no reason, one of mine projects in ASP.NET MVC 3 crashed at launch... I had this error every time:

After some searches, I've found the solution:

• unload your web project
• edit the .csproj file
• remove all "PlatformTarget" elements that you found
• reload your web project

Normally, it should be enough but I have also changed my build configuration to x64 (inspite of Any CPU).

Hope that information can be useful for someone!
