Hello All. I have been working on getting code first migrations working for my asp webpage working for many weeks with lots of frustration. The main reason why i want to use migrations is to add a new column company or something else to my asp websites main login using the db table aspnetusers. There are two similar approaches that i am working on that i have found on the internet. One is this which i have got partially working but its not what i am really looking for.

The last tutorial asks me to make a class library then use enable-migrations -projectname BooksData in the package manager. This does work but I don't want to store my migrations in a separate class library.

The next method is half way down this page

This method is way simpler you just use Enable-Migrations. This is supposed to

Open the Package manager console (PMC) and enter Enable-Migrations
This will create a Migrations folder and a Configuration.cs file. 

The problem is when i do this my package manager says this when i type enable migrations

Server stack trace:

The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

I am thinking that i need to add the project name to the end of enable migrations but i don't know what format to do for a my website.

Has anyone been here and done this before please help.
