Description

UI

• Restore the stylesheet lost (deleted) from APIM 3.10
  

• Slightly rework the Application screen to remove unneeded read-more library
  

• Handle case when there is no Provider defined
  

Management API

• Properly check if an application type is defined when creating or updating an application. For an OAuth2 based application we should check the OAuth2 settings and not the app type itself.
