 If the previous step didn't succeed, it's good to double check that the appropriate csproj exists in your project. Check under **MRTK** / **Providers** / **WindowsMixedReality** / **Shared** / **DotNetAdapter** and confirm that DotNetAdapter.csproj exists. One common case where this file might not exist is if your .gitignore ignores csproj files and you've committed the MRTK files to a remote repo. In this case, please make sure you force add DotNetAdapter.csproj with `git add -f [path/to]/DotNetAdapter.csproj` to make sure it gets committed and cloned for all other collaborators or computers.
