How do you set up routing in a .NET Core API to handle different endpoints?

Sure. Routing in a .NET Core API is the process of mapping HTTP requests to specific actions or controllers. This allows you to create different endpoints for different types of requests.
To setup routing in a .NET Core API, you can use the UseRouting and
UseEndpoints middleware. The UseRouting middleware registers the routes in your application. The
UseEndpoints middleware maps the routes to actions or controllers.
The following code shows how to setup routing in a .NET Core API:
C#
app.UseRouting();
app.UseEndpoints(endpoints =>
{
    endpoints.MapGet("/", () => "Hello World!");
});
In this example, we are registering a route for the / endpoint. This route will map to the action that returns the string "Hello World!".
You can also use the MapPost, MapPut, MapDelete, and
MapPatch methods to map routes to different HTTP methods.
The following code shows how to map routes to different HTTP methods:
C#
app.UseRouting();
app.UseEndpoints(endpoints =>
{
    endpoints.MapGet("/", () => "Hello World!");
    endpoints.MapPost("/users", () => "Create a new user");
    endpoints.MapPut("/users/{id}", (id) => "Update the user with id {id}");
    endpoints.MapDelete("/users/{id}", (id) => "Delete the user with id {id}");
    endpoints.MapPatch("/users/{id}", (id) => "Patch the user with id {id}");
});
In this example, we are mapping routes to different HTTP methods for the 
/users endpoint. The /users endpoint can be used to create, update, delete, and patch users.
By using routing, you can create different endpoints for different types of requests. This allows you to organize your API and make it easier to use.
Here are some additional considerations when setting up routing in a .NET Core API:
The names of the routes: The names of the routes should be descriptive and easy to remember.The HTTP methods for the routes: The HTTP methods for the routes should be appropriate for the type of request.The actions or controllers for the routes: The actions or controllers for the routes should be able to handle the requests that are sent to them.
By following these considerations, you can set up routing in a .NET Core API that is clear, concise, and easy to use.
