    How to create multiple sites in one Umbraco V8 instance


    It's been a while since I worked with Umbraco and I´m getting into it again and v8 is just awesome but I´m having a bit of a problem creating multiple websites and testing them in localhost.

    I've tried to find a explanation/guide/tutorial to do this and all I get are for versions previous to v8 and for example when I try to add and set to true

    Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

    But I just can´t see the sites working. I don't know if I'm missing something, if there are some changes I'm not aware of.

    Can someone help me out, give me some pointers or link me a guide or something?

    Thanks in advance,

    All these things should work on live with a real domains.

    By the way, if you have to check it on localhost, you can setup several fake local domains. Unfortunatly, I don't remeber how :)

    One way to set up your "fake" local domains is using the host file in windows system dir. ...also, I would not create the full .com extention and instead use something like

    hope this help.
