Over the past few years, I've been working on a number of projects in part motivated by the need to replace legacy D3DX functionality. As noted on MSDN, all versions of D3DX are deprecated and are not shipped with the Windows 8.x SDK. This includes D3DX9, D3DX10, and D3DX11. There are plenty of options for moving existing code over to newer, more supportable solutions most of which are now shared-source.
I've built a number of porting notes tables for each of these topics, and then realized today I don't have a single place to see it all. So here it is, the "D3DX porting mega-table" for Direct3D 11.

General Helpers
The DirectX Tool Kit provides a number of helpers that are designed to simplify Direct3D 11 programming in the tradition of the original D3DX library. You can find the library on CodePlex.

HLSL Functions
The HLSL compiler, shader reflection API, and related functionality has been broken out into it's own D3DCompile DLL for some time. D3DCompile is in the Windows 8.x SDK and is included with VS 2012 and VS 2013 Preview.
D3DXCompileShaderFromFile | D3DCompileFromFile |
D3DXCompileShader | D3DCompile |
D3DXCompileShaderFromResource | No direct equivalent. Can use resource APIs and then D3DCompile above. |

Texture Functions
The DirectXTex library is primarily intended for texture processing offline with tools, although it can also be used at runtime for doing texture block compression, mipmap generation, or handling more general image processing needs. DirectXTK is intended for use at runtime with light-weight helpers and image loaders, but does not provide support for general runtime texture format conversion. You can find both libraries on CodePlex.

Note
Careful readers will note that there are a few omissions from this table.
- The
ID3DXMatrixStackfrom D3DXMath doesn't have a new version, but it's actually pretty easy to implement your own. If someone has a burning need for this, please comment below. - The Precomputed Radiance Transfer (PRT) simulator is only available in closed-source form in legacy D3DX9. There are a number of papers that cover this technology in the literature, and the most generally useful parts of this functionality are the SHmath functions which are available.
- UVAtlas is only available in closed-source form in legacy D3DX9. Again, this technology is covered in the literature.
- Geometry processing is the biggest missing area of functionality, particularly the operations for computing tangent frames, optimizing vertex and index buffers, and generating adjacency information. These are part of the 'Future Work' proposal project DirectXMesh.
