Majorsilence.Forms.WindowsFormsInterop

Migrate a WinForms application one screen at a time, instead of all at once.

A Windows-only bridge that lets real System.Windows.Forms forms and Majorsilence.Forms forms live in the same process, in both directions. On Windows, Avalonia's Win32 backend shares the existing Win32 message pump, so both toolkits are serviced by a single Application.Run — no second thread and no second message loop.

That makes an incremental migration practical: port the screens that matter, keep the rest on real WinForms, and ship working software the whole way through. When every screen is over, drop this package and the app is cross-platform.

Windows-only by definition — System.Windows.Forms does not exist on macOS or Linux. Off Windows it builds as an empty placeholder assembly so a cross-platform solution still compiles everywhere; calls throw PlatformNotSupportedException at runtime.

Install

dotnet add package Majorsilence.Forms.WindowsFormsInterop

Direction A — open a legacy WinForms form from a Majorsilence.Forms app

using Majorsilence.Forms.Interop;

WindowsFormsInterop.Show (new LegacyReportForm ());                  // modeless
var result = WindowsFormsInterop.ShowDialog (new LegacySettingsForm ());

Direction B — open a Majorsilence.Forms form from an existing WinForms app

Call InitializeMajorsilence() once in Program.Main, after WinForms initializes:

using Majorsilence.Forms.Interop;

WindowsFormsInterop.InitializeMajorsilence ();

// … later, from a WinForms event handler:
WindowsFormsInterop.ShowMajorsilenceForm (new NewDashboardForm ());

Call these on the UI (STA) thread. From a background thread, marshal first:

Majorsilence.Forms.Application.RunOnUIThread (() => WindowsFormsInterop.Show (form));
