Q: Azure Bot Service Sample AuthenticationBot Sign-in card not working (application/vnd.microsoft.card.oauth) I am following this tutorial using the v4 SDK.
Add authentication to your bot via Azure Bot Service
Put simply, I click on the "Sign In" button from the OAuthPrompt card, a window pops up with the title "Sign In" and the screen is blank.  This is using the bot service emulator.
I could be wrong but I feel like it's something to do with the content type.
application/vnd.microsoft.card.oauth

I wish I had more information to offer.
From the samples, I get the same outcome whether I use the BotAuthenticationMSGraph or AuthenticationBot example.

A: Thanks for the assistance.  I've managed to progress but am not fully over the line yet.  Maybe it's clearer for others, but for me, I followed what I thought were the instructions and did this:


*

*Create Azure AD v2 Application (apps.dev.microsoft.com)

*Create BOT Registration (Azure Portal)
... but in step 1. above, it automatically creates the app for you when you create the "Bot Channels Registration" so step 2 of creating the application is not required  I created a second app and used that one in my settings and I think that's where I was going wrong.
Thanks for your help.
On another note, once the above was corrected and I removed myself from the company Wifi, it all came good.  Network blocking issue!
