MVC1005: Cannot use UseMvc with Endpoint Routing
| Value | |
|---|---|
| Rule ID | MVC1005 |
| Fix is breaking or non-breaking | Non-breaking |
Cause
UseMvc was invoked as part of startup.
Rule description
Using MVC via xref:Microsoft.AspNetCore.Builder.MvcApplicationBuilderExtensions.UseMvc%2A or xref:Microsoft.AspNetCore.Builder.MvcApplicationBuilderExtensions.UseMvcWithDefaultRoute%2A requires an explicit opt-in inside Startup.ConfigureServices. This is required because MVC must know whether it can rely on the authorization and CORS Middleware during initialization.
How to fix violations
If the app requires legacy xref:Microsoft.AspNetCore.Routing.IRouter support, disable xref:Microsoft.AspNetCore.Mvc.MvcOptions.EnableEndpointRoutingusing any of the following approaches in Startup.ConfigureServices:
services.AddMvc(options => options.EnableEndpointRouting = false);
If legacy IRouter support is not required, replace the call to UseMvc with UseEndpoints. For more details, see the migration guide.
