Hi team, when will release sr9 please? Looking forward to the window memory leak fix in sr9.

The promised hot and new CollectionViewHandlers still didn't materialize, even in RC1:

Visual Studio Version is Version 17.12.0 Preview 2.0
dotnet--version is 9.0.100-rc.1.24452.12

What am I missing @davidortinau ?

[baaaaif]

maybe the <MauiVersion>9.xx</MauiVersion> in your csproj?

[ukehartmann]

@DDHSchmidt the latter is what i've been experimenting with ever since .NET 7 and i can only concur. It's been useless and i had hopes that the glamorous blog posts would yield some results. So far it's been a letdown as the most helpful libraries we use do not get trimmed correctly and adding manual exceptions to the trim doesn't really make that option that desirable for quick improvements in file size and performance.

Point in case... If you use third party libraries, you live and die by that sword!

[ukehartmann]

Obviously, but some people prefer to ship products over not having any dependencies.

[Stedy59]

My statement wasn't "all encompassing." If you are having an issue with "one" of your dependencies, how are you shipping, let alone, in a state you desire or, require? Context AND perspective is important...

[ukehartmann]

@Stedy59 so you obviously do not use MAUI but build everything from scratch, right?

I've tried the new HybridWebView control in both preview 7 as well as RC1. I'm just trying out the example in the online documentation (send messages from C# to JS and vice versa). This works fine on Windows, but on Android only the messages from C# to JavaScript work. Sending messages from JS to C# leads to an exception (System.Reflection.TargetInvocationException). I can provide a repro, but it's just the example in documentation.

On a different app when I try this, I get a Java.Lang.RuntimeException Message=java.lang.Throwable: A WebView method was called on thread 'JavaBridge'. All WebView methods must be called on the same thread.

Any suggestions? Are you already tracking this as a bug, or could the online documentation be wrong in some way? BTW I don't have this problem on .Net 8, using the experimental HybridWebView control on github from Eilon - as messages work fine in both directions for Android.
