Hmmm... that builds for me with the latest build. This error was an issue in the pre-release build (which was flagging this as a warning not an error), but I fixed those issues a couple of days ago.

Make sure you have the latest Github build.

I had to apply 

<PropertyGroup>
    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
  </PropertyGroup>

to the AlbumViewBusiness.csproj & WestWind.Utilities.csproj to eliminate this issue
