iOS Build Succeeds but NewBindingMaciOS Namespace Not Found in MainPage.xaml.cs

### Description

When building the project, the build succeeds and the framework is generated. However, when trying to use the iOS binding in [MainPage.xaml.cs] I get the following error is `The type or namespace name 'NewBindingMaciOS' could not be found (are you missing a using directive or an assembly reference?)`

### Steps to Reproduce

1. Build the solution, including the NewBinding.MaciOS.Binding project.
2. Build the Maui project.
2.In the Maui project (e.g., MainPage.xaml.cs), add the following code:
```
#if IOS || MACCATALYST
using NewBinding = NewBindingMaciOS.DotnetNewBinding;
#endif
```
```

```
Please advise how to ensure the iOS binding is correctly referenced and available in the Maui project.

_No response_

### Environment

- OS: Mac 15
- .NET MAUI: 9.0
- Target platforms: IOS, Mac catalyst.

从 MainPage.xaml.cs 和 issue 中显示的条件 ProjectReference 开始，然后将 NewBinding.MaciOS.Binding 项目的输出与 MAUI 目标框架进行比较。当 NewBindingMaciOS.DotnetNewBinding 命名空间能够在 iOS 和 Mac Catalyst 构建中解析，并且 MAUI 项目能够成功构建时，即表示完成。
