   XNA 3.0 Unleashed PerformanceChecker problem
  I recently bought the XNA Game Studio 3.0 Unleashed book by Chad Carter, and it has a programming sample in chapter 3 called XNAPerfStarter which is a console application that uses a library called XNAPerformanceChecker to do benchmark measurements. I coded this exactly as it is in the book, and tried running it, but get an error: "System.BadImageFormatException: Could not load file or assembly 'XNAPerformanceChecker, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load the program with an incorrect format. File name: 'XNAPerformanceChecker, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' at XNAPerfStarter.Program.Main(String[] args)"I am on a Windows 7 64-bit machine using Visual C# 2008 Express Edition.I was able to compile and run the previous sample "PerformanceBenchmark" with no problems.I read that this error may be related to the projects being set to x64 instead of x86, but I reset the Solution Platforms to be x86 and it still gives me the error. I looked at the Properties of the two projects, by right-clicking on them in the Solution Explorer, and I see the XNAPerformanceChecker library is correctly set to x86, but the XNAPerfStarter Console App still says its x64, and it does not have the option to change it to x86.Does anyone have any idea what the problem is here?Thanks   
  This book has a companion website. Did you check the errata and the forum for the book?   ;  No, I hadn't checked that yet. Thanks for the suggestion. If I have any further problems, I'll definitely check there.I did figure out how to add x86 to the Console App's Solution Platforms drop down, and it is working now.
