MSBuildWorkspace.Create() - Supported languages is zero

Question

I am using the roslyn Formatter.Format() method to format some c#.

One of the parameters takes a Workspace object which can be created using MSBuildWorkspace.Create().

However, when I run the code I get a runtime exception because the workspace comes back with no supported languages. If I run this in console application it works fine.

Any ideas?

Make sure to deploy Microsoft.CodeAnalysis.CSharp.Workspaces.dll and/or Microsoft.CodeAnalysis.VisualBasic.Workspaces.dll with your app.

The workspace dynamically discovers which languages it has support for by loading those assemblies.
