Nuget with Build configurations

Question

I'm moving over a project to make it into a nuget package. The project has preprocessor directives in it to check which custom build configuration the developer is in. If they are in Build config A then it pulls A service settings, if they are in B, then it pulls B's settings. The problem is when I package this service up and the nuget package is being used in a separate process with the same build configuration it doesn't respect the devs build configuration choice because the nuget has been compiled with whatever setting it was built in. We have set it up into 3 dlls in a single nuget package.

Is there a way to choose which nuget dll it uses based on the custom build configuration without modifying the csproj code?

This is not supported as far as I am aware with the NuGet. You can only have one NuGet package with a specific build configurations in a single project's file. Moreover, NuGet now only supports multiple .NET framework versions, not supported multiple configurations.

You can have different NuGet packages if you have different build configurations. This project is specific use by library authors who have platform specific projects that need different NuGet packages.

Besides, It may be simpler to not use NuGet to add the assemblies to your project. Just use NuGet to pack the package with multiple dlls file, then directly reference the assemblies you need with conditions.
