# Linux-based build for a Windows desktop Quasar client (WinForms, .NET Framework 4.5.2)
# Note: This Linux-based multi-stage Dockerfile builds the Windows desktop client from source.
# The final image contains the built binaries, but the WinForms executable cannot run on Linux.
# This file demonstrates a build workflow intended for porting the project to a cross-platform stack.
