I actually found the answer to my problem so hopefully this will help you. First make sure you add all the .net stuff in visual studio (for some reason they were using the 3.1 core which has been dropped from support)…. On top of that you likely need to add the v3 source for nuget (which I also find really bad)…. By default VS was using the offline version and it couldn’t download the ones it needed. Epic if you see this, build system needs a bit of updating… ---

Wonderful! I can confirm this worked! For anyone who finds this answer later, the exact solution is: 1. Open Visual Studio (you can select Continue Without Code) 2. Navigate to Tools \> Options \> NuGet Package Manager \> Package Sources 3. You’ll most likely see only one source titled “Microsoft Visual Studio Offline Packages” 4. Click the “+” button to add a new source 5. Name it whatever, and type “[https://api.nuget.org/v3/index.json](https://api.nuget.org/v3/index.json)” for the source 6. Click the “Update” button and then make sure it’s checked 7. Run GenerateProjectFiles.bat again it should work now! ---
