ManagedCuda exception about imagestackalignator HOT 1 OPEN

Hi,

this sounds again like the context creation error we had already in some other issue, I just don't find it right now. The problem is that newer Cuda versions than the one I use in this old project create a PrimaryContext for the Cuda libraries like NPP and CUFFT.
So the trick is to also use a PrimaryContext and not a standard context with ImageStackAligntor.
Try to modify line 203 of ImagePresenterDX.xaml.cs from

_ctx = new CudaContext(cudaDevices[0], _device.ComPointer, CUCtxFlags.BlockingSync, CudaContext.DirectXVersion.D3D9);

to

_ctx = new PrimaryContext(0); //choose what ever deviceID you need, this old managedCuda version does not allow to create primary context from CUdevice
_ctx.SetCurrent();

Doing so, NPP will run on the same context as the normal Cuda code and the error message should disappear.

Cheers,
Michael
