I'm trying to create a site using Orchard CMS. To get started, I downloaded / installed Orchard from WebMatrix. I successfully setup a site using the "Default" recipe. I then click the "Files" tab within the accordian along the left side. From here, I can see all of the files in my project. To begin editing within Visual Studio 2012, I click the "Visual Studio" button in the ribbon.
Once inside Visual Studio, I right-click on the solution and select "Rebuild Solution". The solution begins building, but then I receive an error. The error says:
Error 1 Object reference not set to an instance of an object. C:\Users\username\Documents\My Web Sites\Orchard CMS2\Modules\Contrib.Cache\Contrib.Cache.csproj 1
Please note that at this point, I have not even edited a single file. Rather, I created a basic site and attempted to open it in Visual Studio. What am I doing wrong?
