Description Xavier Claessens 2014-07-17 11:03:26 UTC
I'm trying to do a single instance app in C# using GApplication. I create a class that inherit from GLib.Application and override OnCommandLine() vfunc to handle command line arguments in the primary instance.

Internally it is handled using DBus, the primary instance handles the "CommandLine" dbus method and create a GApplicationCommandLine object, and return from the DBus call only when that object is finalized. But that object gets wrapper by gtk-sharp in the generated code using GLib.Object.GetObject(command_line) as GLib.ApplicationCommandLine and it's passed to the OnCommandLine method. That will keep the object alive until the GC eventually decide that it's time to release some memory (i.e. NEVER). So to make it work I have to add a command_line.Dispose() in my OnCommandLine override, which is clearly unintuitive.

I guess the generated code needs a using() statement.
