I'm trying to create an empty ASP.NET 5 WepApplication, and hosting it to azure, there is a problem that I can't understand or resolve, the create app service dialogue doesn't seem to retrieve anything (It did some minutes ago) no Subscriptions, no Resource Group, no AppServicePlan, no nothing, and some of these fields are not even editable, making the Create Button always disabled hence no chance to create the Wep App in App Services.
Note that I got my credentials entered and connected with my Email that has a subscription to Azure and all.
Here are some screen shots that describe this :
The problem :
I was able to fix the issue in Visual Studio 2017 by logging out of my account in Visual Studio and then logging back in.
Visual Studio may be caching your account info from before you started the subscription. Logging out and back in would likely force a refresh of this data.
