    0hi If you search this keyword in your solution globally, You will find some code like: Configure<AppUrlOptions>(options => { options.Applications["MVC"].RootUrl = configuration["App:SelfUrl"]; });We will set the RootUrlofAppUrlOptionsbased on this property.

    0Is this property must same as address of listening?
