[Bug] Compiled bindings not working when using AncestorType

[tranb3r]

Description

Compiled bindings are not working when the binding source is a relative source using ancestor type.
{Binding Source={RelativeSource AncestorType={x:Type local:PeopleViewModel}}, Path=DeleteEmployeeCommand}

Expected Behavior

By definition, the binding source type is defined by AncestorType.
So it should be possible to resolve it at compile time.

Actual Behavior

Unfortunately, this type of binding is not compiled.

Basic Information

• Version with issue: XF 4.5.0
• Last known good version: none
• IDE: VS 2019 16.5.0 preview 5.0
• Platform Target Frameworks: all

Any feedback about this issue?
Is it the same issue described by https://stackoverflow.com/questions/63749594 ?

[tranb3r]

@StephaneDelcroix Is this going to be fixed someday ?

@StephaneDelcroix
Any update? Can we expect compiled bindings to be complete someday?

@StephaneDelcroix @davidortinau
I'd really appreciate an answer.

• is there any hope for a fix ?
• if you cannot fix it, maybe you should explain why, and fix the documentation.

Thanks!

Also, compiled bindings do not seem to work for:

• multibinding
• picker ItemDisplayBinding
• datatrigger

Any reason for that ? Can this be fixed ?

@tranb3r I also get this bug sadly, I noticed that from Multibinding not working. One workaround is to replace those faulty parts in XAML with respective C# code. It works for me at least for multibinding

still its an issue..

[StephaneDelcroix]

if it's an issue in MAUI, file an issue over there

It's not about Maui it's about Xamarin. Currently my company stays at Xamarin since .net Maui has too many flaws and is instable
