Adding project references

If your WiX project consumes the output of another project—like a .wixproj that packages the .exe from a .csproj into an .msi—you can add a project reference to ensure that Visual Studio (and MSBuild for command line and CI/CD builds) builds the projects in the right order.

To add a project reference, right-click Dependencies in the WiX project in Solution Explorer and choose Add Project Reference.

In Reference Manager, select the projects to reference and choose OK.

Now when you build, the referenced projects will build before your WiX project.
