Cast Error on Report Designer When Using MVC Route Attribute

[rcollins]

Hello,

I'm currently evaluating your software for inclusion in a project I'm working on. Our project is using .NET Core 1.1. Your very helpful chat operator Andrew sent me a link to the GitHub Page for the example project "NET Core Samples".

This sample project runs great, but when I attempt to integrate the Stimulsoft Nuget package into our application I receive the following error:

Code: Select all

System.InvalidCastException: Unable to cast object of type 'Microsoft.AspNetCore.Mvc.Internal.AttributeRoute' to type 'Microsoft.AspNetCore.Routing.Route'.

I've tracked the problem down to the fact that our website uses MVC Route attributes. You can easily reproduce the error in the "NET Core Samples" solution (I'm testing with Edit-Report-in-the-Designer project) by adding attributes to the HomeController class:

Code: Select all

    [Route("Home")]
    public class HomeController : Controller
    {...

...and on the Index action method:

Code: Select all

        [Route("Index")]
        public IActionResult Index()
        {
            return View();
        }

When running the project with this modification, you'll have to hit the URL manually to get the error above:

http://localhost:50602/Home/Index

Could you please let me know if there's a way around this problem with our MVC Attribute Routing?

Thanks very much!

Hello,

We reproduced and already fixed the problem, the fix will be available in release 2017.2, which will be available in the end of September.

Thank you.
