Cannot CompileProjection for a mapping derived types between abstract classes with .Include()

Description

When trying to create a mapping between abstract base classes and including their derived concrete implementations, Mapster throws an exception during CompileProjection(). There appears to be an issue in the expression tree generation.

Environment

• Mapster version: 7.4.0
• Mapster.EFCore 5.1.1
• .NET version: net9.0
• EF Core version: 9.0.4

I have tried Mapster 7.4.2-pre02 with net9.0 and net8.0 as well.

Steps to Reproduce

1. Define the following class hierarchy:

public abstract class PocoA
{
    public int Id { get; set; }
}

public class PocoDerived : PocoA
{
    public int DerivedVal { get; set; }
}

public abstract class DtoA
{
    public int Id { get; set; }
}

public class DtoDerived : DtoA
{
    public int DerivedVal { get; set; }
}

2. Configure the mapping:

config.NewConfig<PocoA, DtoA>()
    .Include<PocoDerived, DtoDerived>();
  
config.CompileProjection();

Alternatively, edit the WhenIncludeDerivedClasses test in Mapster.Tests so that the Compile() lines are CompileProjection();

Expected Behavior

The mapping should compile successfully, allowing for projection between these types.

Actual Behavior

An exception is thrown during CompileProjection():

Unhandled exception. Mapster.CompileException: Error while compiling
source=Backend.Services.Models.PocoA
destination=Backend.Services.Models.DtoA
type=Projection
