What are you seeing?

I'm experimenting a bit with multi-layered cake files
Currently working on putting all the base building/testing in a single cake file, and use that for more specific packing tasks in other files
Running inhertiance between the setuped implementation and an abstract base class in the base cake file gives the following error

An error occurred when executing task 'Build'.
Error: The context data has not been setup.

That seems to indicate that it doesn't consider or support reading context data based on inherited classes?

What is expected?

To be able to use data in a base class, in Does calls typed to the baseclass

Steps to Reproduce

Base.cake file:

internal abstract class BaseCake
{
    public FilePath SolutionFile { get; set; }
}

var buildTask = Task("Build")
    .Does<BaseCake>(bc =>
{
    var settings = new DotNetBuildSettings
    {
        Configuration = "Debug"
    };

    DotNetBuild(bc.SolutionFile.FullPath, settings);
});

Pacakge.cake

#load Base.cake

internal class PackageCake : BaseCake
{
}

Setup<PackageCake>(ctx => {
    var pc = new PackageCake(); //code
    return pc;
});

var packTask = Task("Pack")
    .IsDependentOn(buildTask)
    .Does<PackageCake>(pc =>
{
    //code
});

This will casue the Package.cake to fail with

An error occurred when executing task 'Build'.
Error: The context data has not been setup.

This is by design, you can register multiple types by running Setup multiple with different types, if base type was registered this wouldn't be possible.

But you could opt-in to register your base type, i.e. something like below

internal abstract class BaseCake
{
    public FilePath SolutionFile { get; set; }
}

var buildTask = Task("Build")
    .Does<BaseCake>(bc =>
{
    var settings = new DotNetBuildSettings
    {
        Configuration = "Debug"
    };

    DotNetBuild(bc.SolutionFile.FullPath, settings);
});


internal class PackageCake : BaseCake
{
}

{
    var pc = new PackageCake{
        SolutionFile = "MySolution.sln"
    };//code
    Setup(ctx => pc);
    Setup<BaseCake>(ctx => pc);
}

var packTask = Task("Pack")
    .IsDependentOn(buildTask)
    .Does<PackageCake>(pc =>
{
    //code
});

RunTarget("Pack");
