.NET Source Generators 的 target framework 问题

实现 IIncrementalGenerator 的类中，[Generator(LanguageNames.CSharp)] 出现编译警告

[Generator(LanguageNames.CSharp)]
public class PatternsGenerator : IIncrementalGenerator
{
    //....
}

警告信息如下

This compiler extension should not be implemented in an assembly with target framework '.NET 10.0'. References to other target frameworks will cause the compiler to behave unpredictably.

csproj 中 PropertyGroup 部分的内容

<PropertyGroup>
  <TargetFramework>net10.0</TargetFramework>
  <ImplicitUsings>enable</ImplicitUsings>
  <Nullable>enable</Nullable>
  <EnforceExtendedAnalyzerRules>true</EnforceExtendedAnalyzerRules>
</PropertyGroup>

回答

target framework 需要改为 netstandard2.0

<PropertyGroup>
  <TargetFramework>netstandard2.0</TargetFramework>
</PropertyGroup>
