The MicrosoftAccount service has restrictions that prevent the use of http://localhost:54540/ for test applications.
|
|
As such, here is how to change this sample to uses http://mssecsample.localhost.this:54540/ instead.
|
|
|
|
Edit the Project.json file and replace http://localhost:54540/ with http://mssecsample.localhost.this:54540/.
|
|
|
|
From an admin command console first enter:
|
|
notepad C:\Windows\System32\drivers\etc\hosts
|
|
and add this to the file, save, and exit (and reboot?):
|
|
127.0.0.1 MsSecSample.localhost.this
|
|
|
|
Then you can choose to run the app as admin (see below) or add the following ACL as admin:
|
|
netsh http add urlacl url=http://mssecsample.localhost.this:54540/ user=[domain\user]
|
|
|
|
The sample app can then be run via:
|
|
dnx . web
