+  <!--
+    Non-Windows subset of ZB.MOM.WW.MxGateway.slnx — omits the ArchestrA-COM-bound
+    Worker + Worker.Tests projects so the rest of the solution (Contracts, Server,
+    IntegrationTests, Tests) restores and builds cleanly on macOS / Linux.
+
+    The canonical solution on Windows remains ZB.MOM.WW.MxGateway.slnx; this file
+    is purely a developer-experience filter for non-Windows hosts. Use:
+
+        dotnet build src/ZB.MOM.WW.MxGateway.NonWindows.slnx
