Azure Active Directory B2C (AAD B2C) for beginners
У вашего броузера проблема в совместимости с HTML5
I already created 2 blogs on this issue under http://bit.ly/2O7qhLA
and http://bit.ly/2UFb06Y. This is now the screencast showing creation and basic setup of AAD B2C and usage inside a ASP.NET Core web app. In the end I mentioned a more sophisticated sample on GitHub. Here is the missing link: https://github.com/Azure-Samples/active-directory-b2c-dotnetcore-webapp. Have fun!
