SWAGGER Error. The server encountered an error processing the request

Question

I'm getting this error in swagger UI. I'm stock in this error for almost 3 days. Please help me what is the problem. I'm using this as my references https://github.com/abelsilva/swaggerwcf

    [OperationContract]
    [WebInvoke(Method = "PUT",
         UriTemplate = "UpdateJob/{UserName}", BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Json)]
    [SwaggerWcf.Attributes.SwaggerWcfPath("Update Job", "Update a job in Portal")]
    PortalJob UpdateJob(
        [SwaggerWcfParameter(true, "This is the Username assigned to a company to allow service processing")]
        String UserName,
        [SwaggerWcfParameter(true, "This is the populated job object")]
        PortalJob job);

Answer 1

I received this error with SwaggerWCF as well. I was able to determine the problem was a dependency on Newtonsoft.Json by enabling tracing on my application. Here was the error I found.

System.IO.FileLoadException: Could not load file or assembly 'Newtonsoft.Json, Version=8.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

I reinstalled Newtonsoft through NuGet and that resolved my problem.
