UsePathBase does not work as expected in .NET 6

Is there an existing issue for this?

Describe the bug

The application calls app.UsePathBase() before app.UseRouting(), as recommended workaround described here . The controller method is reachable over both /xxx and /MyBasePath/xxx URLs. Swagger displays /xxx as method url.

...
app.UsePathBase("/MyBasePath");

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
  app.UseSwagger();
  app.UseSwaggerUI();
}
app.UseRouting();
...

Expected Behavior

The controller method should be reachable only over /MyBasePath/xxx URL.
Swagger should display /MyBasePath/xxx

Exceptions (if any)

.NET Version

7.0.100

Anything else?

The ASP.NET Core application targets NET 6,.
VS 2022 is used as IDE

[Tratcher]

This is the expected behavior, UsePathBase trims the given segments from the matched paths, but it doesn't reject requests that do not match. If you only want to match requests with this prefix then you should include it in the routes, or use the new 7.0 route groups feature.
