I went ahead and installed C# Express 2008 and XNA 3.0. Now I can open the svn source! Cool! Great tutorials Mike, thanks.

jnbutler, The new[]{}; syntax is a part of C# 3.0 and will probably need .Net 3.5 and VS2008 to compile correctly. You could use syntax like

new VertexPositionColorTexture[]{ … }

as well to alleviate this issue.

Yes, all projects have been updated to VS2008

Should I be using VS2008? I did not have any problems with the code until I came to this:
myVertices = new[] {
new VertexPositionColorTexture(new Vector3(-0.5f, 0.5f, 0), myColor, new Vector2(0, 0)),
new VertexPositionColorTexture(new Vector3(0.5f, 0.5f, 0), myColor, new Vector2(1, 0)),
new VertexPositionColorTexture(new Vector3(-0.5f, -0.5f, 0), myColor, new Vector2(0, 1)),
new VertexPositionColorTexture(new Vector3(0.5f, -0.5f, 0), myColor, new Vector2(1, 1))
};

myIndexes = new[] { 0, 1, 2, 1, 3, 2 };

I’m getting syntax error value expected at the square brackets in VS 2005 Pro.
I guess I will have to download VS 2008 Express huh?

I type O’d also, that is Window_ClientSizeChanged not Windows. Sorry.

Hey Mike, can you add to the tutorial how you are organizing all of your source in the engine and demo projects? In this tutorial when you are describing the object framework you don’t state what source files the code should be in, existing one or a new cs file.
I downloaded the svn source so I can see that you put some in their own cs files even in their own directories.
BTW, was the svn source created with VS2008? I can’t open it with VS2005

In the HMGame constructor you left out the underscore character in Windows_ClientSizeChanged

I overlooked these lines in the PDF at page 9:
if (null != myEffect.Parameters["World"]) myEffect.Parameters["World"].SetValue(World);
if (null != myEffect.Parameters["View"]) myEffect.Parameters["View"].SetValue(HMCameraManager.ActiveCamera.View);
if (null != myEffect.Parameters["Project"]) myEffect.Parameters["Project"].SetValue(HMCameraManager.ActiveCamera.Projection);

That fixed it! (and makes much more sense too)

Never mind. I found http://code.google.com/p/hmengine-xna/, downloaded TurtoiseSVN and checked the Trunk out
I will find the problem with this working example.
