Is it possible to add a nuget package as runtime only dependency?

I'm working with the following projects:

• MyFramework.csproj (class library)

• MyCustomerApp.csproj (class library)

  References MyFramework

• MyLauncher.csproj (Executable program)

  references MyLauncherDependency.nupkg

MyCustomerApp.csproj is the 'runnable' project which works like so:

1. MyLauncher.exe is copied from the MyLauncher project to the output of MyCustomerApp
2. When running MyLauncher.exe, this uses Assembly.Load(..) to load the MyCystomerApp.dll

There's a specific reason as to why we have this mechanism which I won't get into - consider it out of scope for now.

Now here's the problem; MyLauncherDependency is a dependency of MyLauncher, but its not a dependency of MyCustomerApp. Therefore MyLauncherDependency is not a compile time dependency of MyCustomerApp - but it is a runtime dependency - because it needs MyLauncherDependency.dll at runtime.

I don't want to add MyLauncherDependency.nupkg to MyCustomerApp because I don't want to give engineers access to classes from MyLauncherDependency in MyCustomerApp.

So my question is: How can I add MyLauncherDependency.nupkg (or MyLauncherDependency.nupkg) to MyCustomerApp as a runtime only dependency?
