JumpList and PublishAOT support ?

[latop2604]

Hello, I have an Avalonia app build using PublishAOT.

And I would like to add JumpList support to it.

Using the following code snippet it work, but when running the AOT version the app crash with an InvalidProgramException.

Do you know is AOT is supposed to work with Vanara lib. And is yes, any idea on why it does not work?

Unhandled Exception: System.InvalidProgramException: Common Language Runtime detected an invalid program. The body of method 'Void CDestinationList..ctor()' is invalid.

// BuiltInComInteropSupport is set to true

var jumpList = new Vanara.Windows.Shell.JumpList();

foreach (strin profile in profiles)
{
    jumpList.Add(new JumpListTask(
        profile ?? "Default",
        "C:\\myAppPath\\myApp.exe"
        )
    {
        Arguments = profile ?? "",
        Description = $"Open with profile {profile ?? "Default"}",
    });
}

jumpList.ApplySettings();

I was able to have something working with the help of C# Discord server.
The source code is available as gist here https://gist.github.com/latop2604/73bd7d8008e7ed925f5713fda9201ced

It Use ComWrapper and ComSourceGenerator. It's strongly based on Vanara source code but with lot of adaptation (that I don't completely understand)

It support only adding Task item to the jump list.

Are you using .NET 7 or 8? It appears to be failing on the constructor of the ICustomDestinationList constructor which calls CoCreateInstance by .NET. I'm afraid you may be running into an incompatibility between an interop library and AOT.

Cool use of ComWrappers. I have been meaning to try this out and see if it is backwards compatible.
