1. First install VS update 2 
  * Download the .iso file 
  * Uncheck the "Update 3" option
  
2. How to use ASP.NET 5 Template?
  * Use an existing project of ASP.NET 5 as template 
   (maybe there is another approach or maybe it's no longer an issue after successfully installed the DNX package)
  
3. How to install the DNX itself?
  * In VS, in the Package Manager windows enter: Install-Package dnx-clr-win-x64 -Version 1.0.0-rc1-update1 -Pre
    (This will download DNX from nuget: 
     https://www.nuget.org/packages/dnx-clr-win-x64/1.0.0-rc1-update1, 
     and install in on the machine in the user directory: C:\Users\<username>\.dnx)
  
4. How to configure the EF with this DNX?
  * Open command line in the *project* folder (not the solution)
  * Enter in the cmd:
    - set path=%path%;%USERPROFILE%\.dnx\packages\dnx-clr-win-x64\1.0.0-rc1-update1\bin
    
    - dnu restore (only once, first time using/install the db on the machine)
    
    - dnvm use 1.0.0-rc1-update1 -p (only once, the same as above)
    
    - dnx ef migrations add Initial (do it after each changment in the Model, 
                                      the name 'Initial' need to be different each time, it's for db versioning)
    - dnx ef database update (do it after each changment in the Model, the same as above)
