Not supported by Swagger 2.0: Multiple operations with path

Question

I have integrated swagger in WebApi 2 application. It works fine when application has single controller. When I added second controller in the application. I got following

Answer 1

In the file AppStart/SwaggerConfig.cs

First one, you must import Linq

using System.Linq;

And add in the same file, this line

c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());

just inside of:

GlobalConfiguration.Configuration 
                .EnableSwagger(c =>
                    { ...

One consideration: In your controllers, you must use the Http methods :

[HttpGet]
[Route("something")]
public List something(){....}

[HttpGet]
[Route("something2")]
public List something2(){....}

[HttpPost]
[Route("mypost1")]
public List mypost1(){....}

[HttpPost]
[Route("mypost2")]
public List mypost2(){....}
