Net8 EFCore Mysql 连接 The service collection cannot be modified because it is read-only”

我根据你的文章 Net8 EFCore Mysql 连接
//注意：在动态对EntityFrameworkCore中间件进行实例化时，必须使用“AddDbContextPool” 内置方法替换“AddDbContext”内置方法，
//否则就会出现异常：“System.InvalidOperationException: The service collection cannot be modified because it is read-only”

我把AddDbContext改为AddDbContextPool 还是这个错误请问怎么解决

    builder.Services.AddDbContextPool<SqlContext>(options =>
    {
        var serverVersion = ServerVersion.AutoDetect(sqlConnection);  //mysql版本: {8.2.0-mysql}
        options.UseMySql(sqlConnection, serverVersion);

    });
