SB, et al. The attached sample and code within the post have been updated to use the Visual Studio 11 Beta syntax.

SB, I'll get in touch with Igor about updating the sample.

In the meantime, please see changes to the Beta on our blog here:

blogs.msdn.com/.../changes-in-vs-11-beta-for-c-amp.aspx

As you can see there, you should change

grid to extent,

and change

restrict(direct3d) to restrict(amp).

You can probably delete the word mutable, that is rarelly needed.

Outdated sample, I guess, since the documentation would seem to agree with the compiler's assessment. Perhaps working samples could be provided? I'm sure we'd all appreciate that.

So, this line doesn't compile at all in Visual Studio 11 (Ultimate) Beta and Windows 7:

parallel_for_each(dataView.grid, [=] (index<1> idx) mutable restrict(direct3d)

error C2039: 'grid' : is not a member of 'Concurrency::array_view<_Value_type,_Rank>'

error C3936: 'direct3d' : unrecognized restriction specifier

What's the frequency, Kenneth?

Sorry, now I am just reading that GPU debugging is not supported on Win7.

Thanks, great! Hower I have one problem. Debugging is not working. Do you know why?
