The url that works is in the format of:

[api]/[ControllerName]

I was trying urls that were variations of:

[api]/[ControllerName]/[MethodName]

NOTES:

• this is an HttpGet method
• this is decorating the ws class: [Route("api/[controller]")]
• if there are 2 HttpGet methods in that controller, without [Route]s it will throw:
• "The request matched multiple endpoints."
• If one of the HttpGet methods in the controller has a [Route] the framework will find the method that does not have the [Route]
