Description Alexander Köplinger [MSFT] 2017-08-23 01:00:18 UTC
We recently added the C# Interactive REPL from roslyn. However, it doesn't actually work for anything that's not completely trivial:

    $ csi
    Microsoft (R) Visual C# Interactive Compiler version
    Copyright (C) Microsoft Corporation. All rights reserved.
    Type "#help" for more information.
    > 1+1
    > Console.WriteLine("test")
    (1,1): error CS0012: The type 'Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

This looks like some Roslyn issue which I could not track down yet because adding any System.Runtime.dll to the folder with csi.exe makes it work
Comment 3 Alexander Köplinger [MSFT] 2017-10-09 15:34:50 UTC
https://github.com/mono/mono/pull/5737. I'll see if I can come up with a test case for the Roslyn folks
