MVC1005: Cannot use UseMvc with Endpoint Routing

  • Artikkeli
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 UseMvc or UseMvcWithDefaultRoute 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 IRouter support, disable 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.

When to suppress warnings

Do not suppress a warning from this rule.
