I am following this article on how to configure Telerik Reporting on ASP.NET MVC 5 and .NET 4.6.1 Using HTML5 ASP.NET MVC Report Viewer in a web application then Telerik Reporting REST Web API to Web Application
One thing I could not do in this is Register routes
If I do it, I get following error. I think its conflicting with some other routes, not sure where it is...
I tried commenting out MVC routes registration, that also gives same error
//RouteConfig.RegisterRoutes(RouteTable.Routes);
A route named 'Resources' is already in the route collection. Route names must be unique. Parameter name: name
So without registering the route when I do POST call to the following URL I get good response.
But If I try to verify the reports as per the documentation I get the following error
Any help is greatly appreciated.
Update
Route issue is fixed. removed a duplicate entry in WebApiConfig initialization
When access this URL http://localhost:[portnumber]/api/reports/formats Following error is still not resolved
