jnajerasc commented 6 years ago

Steps to Reproduce

  1. Upgrade to latest Alpha stream for Visual Studio for Mac for this issue https://github.com/mono/Embeddinator-4000/issues/670
  2. In VS for Mac, successfully build C# project that contains a method signature with tuple, such as 
    public MyResultSet<(string name, string value)> GetInfo()
  3. Reference this built dll with Embeddinator's objcgen, and get the exception in the objcgen build log.

Expected Behavior

No exception related to use of tuple

Actual Behavior

The exception is given:

EM0000: Unexpected error - Please fill a bug report at https://github.com/mono/Embeddinator-4000/issues

Unfortunately I don't think we currently support exposing tuples to Objective-C land, I would suggest to create a DTO/POCO and expose it instead.

jcapellman commented 6 years ago

If the tuples are used within a dependency would that work? Or if it were made private within the library?
