SharpDX + MonoGame + Mono x64

[ArcoMul]

Hi,

I am trying to run MonoGame on top of Mono x64 on Windows. I get an error in SharpDX though that the creation of SwapChain fails with an invalid call.

To exclude MonoGame I managed to reproduce the error in one of the SharpDX Samples (Direct3D11, MiniCube). The error it gives is pasted below.

This error occurs with both SharpDX 2.5.1 (version MonoGame uses) and the latest 2.6.3 release.

Are there any known issues related to memory alignment with x64? Or with COM Interop in x64? The only thing I could fine is that someone is working on x64 alignment issues for Direct3D12: https://github.com/sharpdx/SharpDX/commit/070fa52de8828c8fdcc8f2cd468fd37b085cda87

Never tested with x64 Mono but there could be some problem. Could you try the latest 3.0.0 version as I remember that I slightly changed the packing attribute for structures (dev package on main web site)

[ArcoMul]

I'm not able to build the latest version, seems like it can't find the Windows 10 SDK?

To compile with latest 3.0 you need to have Windows SDK 10069 installed.

Also I tried to run a sample with Mono (I guess x86) on Windows and it is crashing on an invalid IL. Don't have time to dig into this but it seems that Mono is currently broken with SharpDX assemblies.
