黑页或404 Asp.NET Core中的每个请求

Question

my Asp.NET Core project returns 404 with Postman or a blank page with a browser after every request. I'm using Asp.NET Core 1.1.2. I already tried to:

• clean the solution
• delete the .vs folder
• restore Visual Studio
• create a new project and copy every file (empty project works)

Startup.cs, appsettings.json, web.config have not been edited.

I have SSL enabled and HTTPS rewrite.

This happenes on both IIS Express and the project directly.

Routing:

app.UseMvc(routes => {
    routes.MapRoute(
        name: "default",
        template: "{controller=Home}/{action=Index}/{id?}");
});

Log:

• Microsoft.AspNetCore.Routing.RouteBase:Debug: Request successfully matched the route with name 'default' and template '{controller=Home}/{action=Index}/{id?}'.
• Microsoft.AspNetCore.Mvc.Internal.MvcRouteHandler:Debug: No actions matched the current request
• Microsoft.AspNetCore.Builder.RouterMiddleware:Debug: Request did not match any routes.

Answer 1

So, the problem was Microsoft.AspNetCore.Mvc.Versioning. With version 1.1.x you need to add "app.UseApiVersioning()" in the configure method after app.UseMvc(...);
