调研方向

未指定任何仓库文件或测试。首先使用 CommunityToolkit.Mvvm 8.4.0 重现最小的部分 ObservableProperty 示例,并检查 ObservableProperty 的源代码生成路径;当对 Item.Returned 的外部访问不再产生 CS0229,同时生成的属性仍能正确编译和运行时,即表示完成。

描述

bug :bug:
Describe the bug

I'm developing a WinUI application with Community Toolkit MVVM 8.4.0.
I switched the properties in my application to use the new format. Here's one example:

[ObservableProperty]
public partial bool Returned { get; set; } = returned;

And this is a simplified version of the constructor for the object:
public partial class Item(bool returned) : ObservableObject

This all works as expected and compiles fine but all uses of the property elsewhere show the Compiler Error CS0229. In this case it shows:
Ambiguity between Item.Returned and Item.Returned.
I only have the one property called Returned.
As I said, it all compiles fine and works correctly but I'm not able to get rid of the error.

Regression

No response

Steps to reproduce

Create a class with the type ObservableObject and create a partial Observable Property. Use it elsewhere in the app.

Example:

public partial class Item(bool returned) {
    [ObservableProperty]
    public partial bool Returned { get; set; } = returned;
}

Then access the property somewhere else in the app.

Example:

var newItem = new Item(false);
newItem.Returned = true;

This shows the compiler error.

Expected behavior

I would like to remove the false alarm.
