UBT C# program project support?

I have an Unreal project with 2 core pieces:

  1. A normal Unreal game project (“GameProject”)
  2. A C# uprogram project (“DotNetProject”)

Currently, GameProject runs a dotnet hosting environment via packaged dlls (hostfxr), and in this environment I load prebuilt dlls of DotNetProject.

I’d like to be able to add DotNetProject as a dependency of GameProject, so that when I’m developing in Visual Studio and make a change to DotNetProject, and then try to run GameProject, it knows to rebuild DotNetProject.

The closest I’ve gotten is running a buildgraph which first calls a dotnet action to build the C# program project, then copies its output to a folder where GameProject looks during packaging. The problem here is I frequently forget to run this graph before my next F5 debugging session, and so I debug with stale dlls.

Is there any way to get UBT and/or Visual Studio to recognize DotNetProject as a dependency of GameProject and automatically build it if it’s out of date?
