Recently I have downloaded DNN source code package 5.6.2 version but I couldn't build the solution successfully. Before build the solution I have made the following changes.

1) Renamed the “Development.config” to web.config
2) Created a Virtual Directory in IIS 5.1 pointing to "C:\DNN\Website"
3)Added "Network Service" on "C:\DNN" folder

Build failure error messages:

Could not get dependencies for project reference 'DotNetNuke.Library.VS2008'

I got stuck here and couldn't find any solution to build the solution successfully. 

I'm having the same problem with community version 05.06.03 but I don't see where you have removed the project reference.
Could you please enlighten me about this?
Does someone know the reason why this happens?

thanks in advance
