I just finished working through problems installing the 7.2.1 source package on Windows 7, SQL 2008 and VS 2010. I was following the instructions found at http://www.dnnsoftware.com/wiki/page/.... I thought I would share my experience.

1. You may find that the assembly references to the Microsoft WebAPI (System.Web.Http, System.Web.Http.Formatting, System.Web.Http.WebHost) and also System.Net.Http in most, if not all, projects aren't found. I assume that this works for some people because they have the WebAPI installed in the GAC (or there is another way for VS to resolve those references that I'm not aware of.) In some project files (.csproj) there is no hintpath given for the reference. In others, the hintpath is to a non-existant "Components\WebAPI\" folder. I modified the .csproj files to provide a hintpath to the dlls in the Packages folder to fix this. The Wiki mentioned above has you edit some things in the solution file before opening it in VS. You may as well just edit the .csproj files to fix the reference too. This seems to have been reported here but nothing has changed in the source package for 7.3.0. I had some problems with other assembly references but I may have created those as I tried to resolve this issue. I didn't start over from scratch to try to reproduce them.
2. You are supposed to compile the solution in Release mode before launching the DNN install. Even if you want to debug it, compile in Release, then compile in Debug, then do the DNN Install. This is discussed at http://www.dnnsoftware.com/forums/for....
