Description

Configuration Binding Source Generator is introduced by .NET8.0, and it works well in my web projects. I attempt to use this generator in my MAUI Blazor App by modifying the .csproj file like:

<Project Sdk="Microsoft.NET.Sdk.Razor">
    <PropertyGroup>
        ...
        <EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
        <EnableConfigurationBindingGenerator>true</EnableConfigurationBindingGenerator>
        ...
    </PropertyGroup>
    ...
</Project>

It does function when targetting to net8.0-android, net8.0-ios, and net8.0-maccatalyst . However, a cs9137 error occurrs when set targetting to net8.0-windows10.0.19041.0. I followed the message and added <InterceptorsPreviewNamespaces>$(InterceptorsPreviewNamespaces);Microsoft.Extensions.Configuration.Binder.SourceGeneration</InterceptorsPreviewNamespaces> to project file, that error still occurrs.

Reproduction Steps

Add codes below in PropertyGroup:

<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
<EnableConfigurationBindingGenerator>true</EnableConfigurationBindingGenerator>
<InterceptorsPreviewNamespaces>$(InterceptorsPreviewNamespaces);Microsoft.Extensions.Configuration.Binder.SourceGeneration</InterceptorsPreviewNamespaces>

Here is my test project TestMauiBlazor.zip.

Expected behavior

The Configuration Binding Source Generator will generate codes, and the compiler will compile the codes successfully.

Actual behavior

The Configuration Binding Source Generator does generate codes. But the compiler throws a CS9137 error and messages " The 'interceptors' experimental feature is not enabled. Add <InterceptorsPreviewNamespaces>$(InterceptorsPreviewNamespaces);Microsoft.Extensions.Configuration.Binder.SourceGeneration</InterceptorsPreviewNamespaces> to your project. "
