I'm developing an LTI module using ASP.Net Core 3.1 and I am having issues getting the OAuth working.

I was following along with  @garth ‌'s post .NET - OAuth2 Workflow: Part 1 - Authrorize Redirect (and parts 2 & 3) but this was written using an older .Net.

Has anyone implemented this with ASP.Net Core 3.1?

I have added most of the code from Garth's post, but he is using an HttpRequestBase (System.Web.MVC) object to retrieve the OAuth request from Canvas and the newer .Net uses HttpRequest (Microsoft.AspNetCore.Http) which doesn't have the same properties.

Thank you,
