Chapter 3 was edited with the CTP version of XNA Game Studio 3.0. As a result the XNAPerformanceChecker.csproj file is incorrect. The result is that the assemblies it references cannot load successfully. This can be corrected by either following the steps here or by overwriting the current .csproj file with the updated one: XNAPerformanceChecker.csproj. Thanks to Pelham for pointing this out in the forums.
In the code there are extra > values after the methods TransformVectorByReferenceAndOut() and TransformVectorByReferenceAndOutVectorAdd(). The > needs to be removed. Thanks to Myth for pointing this out in the forums.
"We then need to add a call to InitializeCamera in the beginning of our LoadGraphicsContent method." should be "We then need to add a call to InitializeCamera in the beginning of our LoadContent method." Thanks to alvin for pointing this out in the forums.
The assignment of the vertexBuffer should be the following code:
vertexBuffer = new VertexBuffer(graphics.GraphicsDevice, VertexPositionNormalTexture.SizeInBytes * vertices.Length, BufferUsage.WriteOnly);
The code listed in the book was not correctly changed from the previous edition. Thanks to Myth for pointing this out in the forums.
