Hi there!

I've several effects in my project which are generated from pre-compiled byte code provided as a static byte array. My effect sends the byte code to the Xna Effect base class with compiler options set to 'None' and effect pool set to 'null'. Those effects are - more or less - global effects that are only used once in the game. No multiple calls to the constructor here!

This method works great on Windows but fails on the Xbox. Does anybody know why that happens?

Btw.: In a #if #else block the system checks for the system and switches to the corresponding compiled code. I've a code block for Windows and a code block for the Xbox.

The effect compiler does not complain about errors while compiling the Xbox code.

Thanks a bunch for your help! :)

Best regards,

Does this effect work if you load it normally through the content pipeline?

If so there must be something wrong in the way you are compiling or loading it, but we'd need to see some code to tell where your problem is.

Yes it works like expected when loaded trough the content pipeline.

In the meantime I've switched to embedding those effects into a resource - that works like a charm. :)

I'm having exactly the same problem...

I have a class with the windows and xbox 360 bytecode of the effect, like this:

And I'm creating the Effect using the compiled bytecode:

Then, I get the following error:
"An unhandled exception of type 'System.InvalidOperationException' occurred in Microsoft.Xna.Framework.dll
Additional information: This resource could not be created."

It works fine on the Windows but not on the Xbox. I checked and I'm sure that the program is using the Xbox 360 bytecode.
I'm using the Effect Compiling Tool to generate both bytecodes. I looked at its source code and both bytecodes appears to be generated correctly...

Could it be the shader? Despite the fact that it is not generating any error during compiling?

It appears that the problem was in the tool that I was using...
I recompiled the shader using the Effect class, replaced the xbox bytecode, and it worked.

What exactly do you mean by "Effect Compiling Tool"?

Sorry for the confusion, I wasn't meaning any Microsoft tool.

It is a very simple tool that compiles a shader code for xbox and windows and copy it to the clipboard:

Btw, Shawn could you help me on this topic:

Problems with deployment and strong names...

That tool you linked to is a GS 1.0 project. You need to make sure you are using a version of the effect compiler that matches the framework version you are going to load that effect into.

I don't know the answer to your other question, sorry.

Thanks for the answer.
I thought that the compiled effect will be the same, whether it was compiled with the GS 1.0 or 2.0.

Not necessarily. You should always match the compiler to whatever runtime version you are using.
