StopProcessingExn since 34.0.1

[goswinr]

Since version 34.0.1 ( and in the current 35.0.0 too) I get an Exception when creating a FSI Evaluation Session while hosting my scripting editor (with FCS) in another CAD app.

As standalone app it still works fine.

I am looking for help to debug this.
Is there a way to see how the FSI session constructor code changed between 33.0.1 and 34.0.1 ?

this error is preceded by
error FS0084: Assembly reference 'FSharp.Core.dll' was not found or is invalid
even though FSharp.Core.dll (4.7.1) is there (in the same folder).

Hmmmm

I think it might be best to open this in http://github.com/dotnet/fsharp with a repro script. There must have been a change there
