Using SSE in c# is it possible?

Question

I was reading a question about c# code optimization and one solution was to use c++ with SSE. Is it possible to do SSE directly from a c# program?

Answer 1

Recently Microsoft has released a beta SIMD vector library (Microsoft.Bcl.Simd) for C# which requires installation of the RyuJIT CTP and works only Windows 8.

You can also just used a native SSE library and invoke it from C#. For example the Yeppp library, see this StackOverflow answer.
