Swagger 2.0 not supported: multiple path operations

Question

I integrated Swagger into the WebApi 2 application. It works fine when the application has one controller. When I added the second controller in the application. I got the following error:

An error has occurred. "," ExceptionMessage ":" Swagger 2.0 not supported: multiple operations with the path 'api / Credential' and the method 'GET'. See Configuration parameter - \ "ResolveConflictingActions \" for a possible workaround "," ExceptionType ":" System.NotSupportedException "," StackTrace ":" in Swashbuckle.Swagger.SwaggerGeneratorOptions.DefaultConflictingActionsResolver ( 1 apiDescriptions)\r\n at Swashbuckle.Swagger.SwaggerGenerator.CreatePathItem(IEnumerable1 apiRistry in Swashbuckle.Swagger.SwaggerGenerator. <> C__DisplayClass7.b__4 ( 2 group)\r\n at System.Linq.Enumerable.ToDictionary[TSource,TKey,TElement](IEnumerableIGrouping 2 group)\r\n at System.Linq.Enumerable.ToDictionary[TSource,TKey,TElement](IEnumerable.

Answer 8

How about reading documents ? He says that Swashbuckle does not support such method signatures. However, you can create a filter operation to install or use the identifier SwaggerOperationAttributeas specified in the the Q & A .
