.NET MVC application using OIDC and embedded Lock

I’m looking for the correct sample project, “MVC Application using OIDC and embedded Lock”, listed on this Auth0 blog post: https://auth0.com/blog/auth0-support-for-aspnet-core/

If this sample project is no longer available, any documentation you can provide that will help us achieve the same result would be very helpful. We’re looking to use the OpenID Connect middleware in a .NET MVC 5 application but use the Lock widget to display the login screen. No tutorials or documentation provide a full example on how to achieve this.

Thanks in advance!

Have you tried here? https://github.com/auth0-samples

All sorts of samples there
