After the installation of .NET MAUI 9 Preview 5, an XAML compilation (XAMLC) issue has arisen.
In general, it is not necessary to explicitly specify the default property such as Content, Children, etc.
The Content is the default property for Page, View, and Toolkit’s Popup, and this XAMLC issue is about the Content property.
If the following error message is encountered during compilation, consider explicitly defining the Content property, as this approach may resolve the issue.
XC0009 No property, BindableProperty, or event found for "Content", or mismatching type between value and property.
ContentPage:
<ContentPage.Content>
<!--- Content goes here -->
</ContentPage.Content>
ContentView:
<ContentView.Content>
<!--- Content goes here -->
</ContentView.Content>
Toolkit’s Popup:
For MAUI Popup follow this approach: Define an intermediate base class and modify your Popups to inherit from it. After the resolution of this issue has been formalized, proceed to remove the overridden Content property.
public class MauiPopup : Popup
{
public override View? Content
{
get => base.Content;
set => base.Content = value;
}
}
This issue can be tracked on GitHub here.
Let me know in the comments if this resolves the issue or if you discover any alternative solutions.
Happy coding. Stay connected as we continue to learn and share the experiences from this exciting journey of being a .NET developer.
