SlimDx can't be used from a VS2015 C++ Project

[0x53A]

When I try to compile a Visual Studio 2015 C++/CLI Project referencing SlimDx, I get the error 'std::errc': has already been defined to be a namespace

I think the issue is that SlimDx includes std::errc as a namespace:

Could you publish a version compiled with VC++ 2015?

I encountered the same problem. I managed to build the SlimDx.dll with vs2015 by changing some code.

@robertxwu I’m stuck with the same problem. I’m wondering how you were able to fix this problem. Are you willing to help me?
Kind regards,
Wouter

@DankersW Surely I would like to help. Do you know how to create a new branch for VS2015?

[DankersW]

@robertxwu No sorry I don’t know how to do that, thank you in advance for the help

@DankersW, the attachment (you have to change its extension to .7z) includes all changes I made to SlimDX-master in order to build them with VS2015.
slimdx-master_vs2015.zip

Note: although a large number of files are included in the attachment, only a very small portion of them were modified.

What you have to do:

1. download the SlimDX master branch
2. replace files/folders with those included in the attachment.
3. open and compile the solution with the latest VS2015

Note: the solution was modified so that only project SlimDX and Effects11 were loaded.

Good luck!

@robertxwu
or here is a good approach.

1. Fork this Repo.
2. Create or new Branck or Just change the same one on your fork.
3. Create a Pull Request with the following. [your name here]/slimdx -> SlimDX/slimdx.
4. Profit?

In vs2019 it's not working, I still get a syntax error: identifier '__RPC__inout_xcount' at Effects11 C:\Program Files (x86)\Windows Kits\10\Include\10.0.17134.0\um\objidl.h, line 14528
It's an issue related to DirectX SDK and Windows SDK 10.0, see here, but I suspect there's something related to c++ language version specs.

Unfortunately no way to solve this (I tried also to change order of include by modifying include path), any advice on that?
