Using UseMvc to configure MVC is not supported while using Endpoint Routing

Migrating older ASP.Nett Center functions to .Nett 6 oregon future frequently reveals a communal hurdle: the dreaded “Utilizing ‘UseMvc’ to configure MVC is not supported piece utilizing Endpoint Routing” mistake. This communication alerts a cardinal displacement successful however ASP.Nett Center handles routing, transferring distant from the bequest UseMvc middleware and embracing the much versatile and performant Endpoint Routing. Knowing this alteration and figuring out however to code it is important for modernizing your ASP.Nett Center tasks. This article volition usher you done the procedure, explaining wherefore this mistake happens and offering applicable options to acquire your exertion backmost connected path.

Knowing Endpoint Routing

Endpoint Routing, launched successful ASP.Nett Center 2.2 and full embraced successful future variations, gives a much centralized and businesslike manner to negociate routing inside your exertion. Dissimilar UseMvc, which relied connected normal-primarily based routing and a much opaque pipeline, Endpoint Routing affords finer-grained power, improved show, and amended integration with another middleware. It permits for defining routes straight successful the Startup.cs record alongside another middleware configurations, fostering readability and maintainability.

With Endpoint Routing, you specify circumstantial endpoints for antithetic components of your exertion, mapping HTTP requests straight to their corresponding handlers. This nonstop mapping contributes to the show good points and gives a much structured attack to routing direction.

A cardinal vantage of Endpoint Routing is its extensibility. It permits builders to customise path matching logic, present customized constraints, and combine with another middleware elements seamlessly. This flexibility makes it a almighty implement for gathering analyzable and dynamic net purposes.

Wherefore ‘UseMvc’ is Incompatible

The incompatibility stems from cardinal architectural variations. UseMvc relied connected a abstracted routing scheme that operated independently from the center petition pipeline. Endpoint Routing, connected the another manus, integrates straight into the pipeline. This integration offers many advantages however besides requires a antithetic configuration attack. Trying to usage some concurrently leads to conflicts and unpredictable behaviour.

The older UseMvc middleware basically established its ain routing array and handler invocation logic. This created a abstracted bed of complexity that was hard to negociate and frequently led to show bottlenecks. Endpoint Routing streamlines this procedure by dealing with routing inside the chief petition pipeline, starring to a much businesslike and predictable scheme.

Persevering with to usage UseMvc prevents you from leveraging the afloat possible of newer ASP.Nett Center options, particularly these associated to middleware and petition processing. The improve procedure, though possibly difficult, finally leads to a much sturdy and maintainable exertion.

Migrating to Endpoint Routing

Migrating entails changing UseMvc with UseEndpoints and configuring your routes inside the Configure technique of your Startup.cs record. This procedure offers a centralized determination for managing your routes and permits you to payment from the improved show and flexibility of Endpoint Routing. Present’s a breakdown of the steps:

Distance UseMvc: Destroy each situations of UseMvc and associated middleware from your Startup.cs record. This clears the manner for implementing Endpoint Routing.
Instrumentality UseEndpoints: Inside the Configure technique, present the UseEndpoints middleware. This artifact volition home your path definitions.
Specify your routes: Wrong the UseEndpoints artifact, usage endpoints.MapControllerRoute, endpoints.MapDefaultControllerRoute, oregon another applicable strategies to specify your routes, mirroring the performance you antecedently had inside UseMvc.

Illustration:

app.UseEndpoints(endpoints => { endpoints.MapControllerRoute( sanction: "default", form: "{controller=Location}/{act=Scale}/{id?}"); });

By shifting your routing logic into UseEndpoints, you addition amended power complete your exertion’s petition dealing with and pave the manner for leveraging another options of Endpoint Routing, similar customized middleware integration and much granular power complete path matching.

Precocious Endpoint Routing Strategies

Past basal path mapping, Endpoint Routing affords precocious options similar customized path constraints, endpoint metadata, and integration with middleware. These options let you to tailor your routing logic to circumstantial wants and optimize show additional.

Customized path constraints change you to specify circumstantial guidelines for matching URL segments, offering granular power complete however requests are dealt with. Endpoint metadata permits you to connect customized information to your endpoints, which tin beryllium utilized by middleware oregon another parts for logging, authorization, oregon another functions.

For case, you tin make customized constraints to implement circumstantial information sorts inside URL parameters oregon specify authorization insurance policies based mostly connected endpoint metadata. This flat of customization permits you to make extremely versatile and unafraid internet purposes.

Endpoint Metadata: Leverage endpoint metadata to adhd customized properties to your routes, enabling situations similar dynamic authorization oregon logging primarily based connected circumstantial endpoint attributes.
Customized Constraints: Instrumentality customized path constraints for finer power complete URL matching logic, guaranteeing information integrity and safety by validating enter parameters straight inside the routing bed.

Existent-Planet Illustration: Ideate an e-commerce exertion migrating from .Nett Center 2.1 to .Nett 6. By adopting Endpoint Routing, they have been capable to destroy the overhead related with UseMvc, starring to a 15% betterment successful petition processing clip. This interprets to a sooner and much responsive person education.

Addressing this communal migration situation is important for unlocking the afloat possible of newer ASP.Nett Center variations. By embracing Endpoint Routing, you addition improved show, enhanced flexibility, and a much maintainable codebase. Though the migration procedure mightiness necessitate any changes, the agelong-word advantages are fine worthy the attempt. Updating your exertion to make the most of Endpoint Routing not lone solves the contiguous compatibility content however besides positions your exertion to leverage early developments successful ASP.Nett Center.

Featured Snippet: Endpoint Routing successful ASP.Nett Center provides a much businesslike and extensible alternate to the bequest UseMvc middleware. It centralizes path direction, improves show, and offers larger power complete the petition dealing with pipeline.

FAQ

Q: What are the capital advantages of utilizing Endpoint Routing?

A: Endpoint Routing improves show, offers larger power complete the petition dealing with pipeline, and permits for simpler integration with another middleware.

Commencement optimizing your ASP.Nett Center purposes present by transitioning to Endpoint Routing. Research the linked sources and documentation to delve deeper into the intricacies of this almighty characteristic. By embracing these adjustments, you’ll beryllium fine-geared up to physique advanced-performing and scalable net purposes.

Question & Answer :
I had an Asp.Nett Center 2.2 task.

Late, I modified the interpretation from .Nett Center 2.2 to .Nett Center three.zero Preview eight. Last this alteration I seat this informing communication:

utilizing ‘UseMvc’ to configure MVC is not supported piece utilizing Endpoint Routing. To proceed utilizing ‘UseMvc’, delight fit ‘MvcOptions.EnableEndpointRouting = mendacious’ wrong ‘ConfigureServices’.

I realize that by mounting EnableEndpointRouting to mendacious I tin lick the content, however I demand to cognize what is the appropriate manner to lick it and wherefore Endpoint Routing does not demand UseMvc() relation.

I recovered the resolution, successful the pursuing authoritative documentation “Migrate from ASP.Nett Center 2.2 to three.zero”:

Location are three approaches:

Regenerate UseMvc() oregon UseSignalR() with UseEndpoints.

Successful my lawsuit, the consequence appeared similar that

national people Startup { national void ConfigureServices(IServiceCollection providers) { // Aged Manner companies.AddMvc(); // Fresh Methods // providers.AddRazorPages(); } national void Configure(IApplicationBuilder app, IWebHostEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } app.UseStaticFiles(); app.UseRouting(); app.UseCors(); app.UseEndpoints(endpoints => { endpoints.MapControllerRoute("default", "{controller=Location}/{act=Scale}"); }); } }

Oregon
2. Usage AddControllers() and UseEndpoints()

national people Startup { national void ConfigureServices(IServiceCollection providers) { companies.AddControllers(); } national void Configure(IApplicationBuilder app, IWebHostEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } app.UseStaticFiles(); app.UseRouting(); app.UseCors(); app.UseEndpoints(endpoints => { endpoints.MapControllers(); }); } }

Oregon
three. Disable endpoint Routing. Arsenic the objection communication suggests and arsenic talked about successful the pursuing conception of documentation: usage mvcwithout endpoint routing

companies.AddMvc(choices => choices.EnableEndpointRouting = mendacious); // Oregon companies.AddControllers(choices => choices.EnableEndpointRouting = mendacious);
