Roslyn scripting on CoreCLR (.NET CLI and DNX) and in memory assemblies

For a while now, the Roslyn C# scripting APIs (Microsoft.CodeAnalysis.CSharp.Scripting) have been portable, and supported cross platform usage. However, I recently ran into a few difficulties regarding using the Roslyn Scripting APIs in .NET CLI (which is replacing DNX) context. The solution was to use a lower level unmanaged CoreCLR API – and since they it’s not that well documented, I thought it would be beneficial to document it in a blog post.
