  • typeof(x).Assembly is now typeof(x).GetTypeInfo().Assembly
  • MongoCollection has changed
  • StringComparison.InvariantCultureIgnoreCase is gone, easy replacement
  • Configuration + Sections are totally different
  • HttpContext and HttpRequest etc. now found in Microsoft.AspNetCore.Http.Abstractions - Microsoft.AspNetCore.Http.HttpRequest
  • Request.RequestUri is now various new properties, for example Request.Host (a HostString)

Git blackbelt commands
# Change the config editor to notepad
git config --global core.editor notepad
# ...and then edit the config
git config --global --edit
# Revert master back by 5 commits
git revert --no-commit HEAD~5..
# Revert master back by 5, but do it so there you get a "Revert commit" for each commit you reverted (this opens Vim)

Oauth2 Explanation

OAUTH2

The Problem

I’m a web app that wants to allow other web apps access to my users’ information, but I want to ensure that the user says it’s ok.

The Solution

I can’t trust the other web apps, so I must interact with my users directly. I’ll let them know that the other app is trying to get their info, and ask whether they want to grant that permission. Oauth defines a way to initiate that permission verification from the other app’s site so that the user experience is smooth. If the user grants permission, I issue an AuthToken to the other app which it can use to make requests for that user's info.

Note on encryption

Oauth2 has nothing to do with encryption -- it relies upon SSL to keep things (like the client app’s shared_secret) secure.
