+Add a reference to the `Library` project using [dotnet reference add](../../core/tools/dotnet-reference-add.md). This command adds a `<ProjectReference>` element to the App.fsproj file, which tells the compiler that the App project depends on the Library project:
 
 ```dotnetcli
 dotnet add src/App/App.fsproj reference src/Library/Library.fsproj

+> If you skip this step and try to build the App project, you'll get a compilation error because the `Library` module won't be found. If this happens, you can either run the `dotnet add reference` command or manually add the `<ProjectReference>` element shown above to your App.fsproj file.
