TcBuild not support satellite assemblies with language specific resources.
Satellite assemlies are added to zip file in root folder, not in language specific subfolders, for example "fr", or "cs".
Do you plan add it?

TcBuild not support plugin icon, that shows as folder icon on root.
Do you plan add it?

Migrate to .NET 5.

Native DllExports
Look if DNNE can to the job.

Injecting the Plugin Wrapper Code
Try to use c# Source Generators
to dynamically generate and inject wrapper classes.

Build Task static Assembly analysis
Try to use System.Reflection.PortableExecutable.PEReader as used by DNNE.
To read plugin type information needed for post-processing and zip generation.

Project Structure

• TcBuild
  • as one nuget containing everything needed,
    or as meta nuget referencing everything as distinct nugets
• TcBuild.Generator
  • source generator
• TcBuild.Target
  • post processing build target
• TcPluginBase
  • Base types required for plugin authors

Steps

• Proof of concept - (net 5 + native exports + source generator)
• Create a working TcBuild nuget
• Implement FileSystem Plugin
• Implement Lister Plugin
• Implement Content Plugin
• Implement Packer Plugin
• Implement QuickSearch Plugin

Is this project alive?
I've got an exception

Hi,

I get a "There was code at the end" exception when I try to create a PackerPlugin.

I assume the reason are the following callsignatures (they have one opening brace and two closing braces):

WcxWrapper.cs:
_callSignature = $"PackFiles ({packedFile}, {subPath}, {srcPath}, {flags.ToString()}) - {addList.Count} files)";
_callSignature = $"DeleteFiles ({packedFile}) - {deleteList.Count} files)";
