How do you enforce lowercase routing in ASP.NET Core?

Question

In ASP.NET 4 this was as easy as routes.LowercaseUrls = true; in the RegisterRoutes handler for the app.

I cannot find an equivalent in ASP

Answer 1

As other answers indicate, adding:

services.Configure(options => options.LowercaseUrls = true);

before

services.AddMvc(...)

works great, but I also want to add that if you use Identity, you will also need:

services.AddIdentity(options =>
{
    var appCookie = options.Cookies.ApplicationCookie;
    appCookie.LoginPath = appCookie.LoginPath.ToString().ToLowerInvariant();
    appCookie.LogoutPath = appCookie.LogoutPath.ToString().ToLowerInvariant();
    appCookie.ReturnUrlParameter = appCookie.ReturnUrlParameter.ToString().ToLowerInvariant();
});

And obviously, replace both IdentityUser, and IdentityRole with your own classes if required.

I just tested this with .NET Core SDK 1.0.4 and the 1.0.5 runtime.
