Migrated web service to .NET Core 2.0 and returning json

Question

I have migrated my web service to .NET Core 2.0, it works fine but I have problem with getting response as json string.

Method on api:

    [HttpGet]
         


        

Answer 1

Well it appears that in .NET Core 2.0 [Produces("application/json")] has changed and it is serializing string outputs to json so I had it serialized twice... solution for this os to replace [Produces("application/json")] with [Produces("text/plain")] ovet the method / controller
