RF0111: Button getter must create a Callable

For a C# project using Reckfell.NET.Sdk 1.0.0. Fix the first build error first: later messages may be a consequence.

Cause

The button property has a block body, setter, initializer or returns a field rather than a recognized Callable creation.

Fix

Use an expression-bodied getter with Callable.From(...) or new Callable(...). Do not store the button in a backing-field auto-property.

Failing example

Save the file in a test C# project and run dotnet build. This version intentionally fails to build.

using Reckfell;

namespace DiagnosticExamples.RF0111;

[Tool]
public partial class Example : Entity
{
    public int Count { get; private set; } = 7;
    [ExportToolButton("Reset")] public Callable ResetButton { get { return Callable.From(Reset); } }
    private void Reset() => Count = 0;
}

Expected messages: RF0111.

Working version

Replace the failing version with these files; do not keep both declarations in the project.

using Reckfell;

namespace DiagnosticExamples.RF0111;

[Tool]
public partial class Example : Entity
{
    public int Count { get; private set; } = 7;
    [ExportToolButton("Reset")] public Callable ResetButton => Callable.From(Reset);
    private void Reset() => Count = 0;
}

Result

The generator recognizes the direct Callable.From(Reset) expression; calling the button resets Count.
