ASPNet Core - call is ambiguous in Startup.cs configure

Asp.net .net core 461

A dependency in my .json project is throwing ambiguity errors, I'm having trouble localizing it. Any help is appreciated!

This is similar to this question , but it's not so obvious (to me) where the problem is.

Startup.cs

project.json
