.net7没有Startup注册报错：Object reference not set to an instance of an object.

[pcvc]

var builder = WebApplication.CreateBuilder(args);

// .......

var app = builder.Build();

var _senparcSetting = app.Services.GetService<IOptions>()!.Value;
var _senparcWeixinSetting = app.Services.GetService<IOptions>()!.Value;

//由下面这句引起的：
app.UseSenparcGlobal(app.Environment, _senparcSetting, globalRegister => { })
.UseSenparcWeixin(_senparcWeixinSetting, _senparcSetting)
.RegisterWxOpenAccount(_senparcWeixinSetting);

/////////////////////

app.UseSenparcWeixin(app.Environment,
null /* 不为 null 则覆盖 appsettings 中的 SenpacSetting 配置*/,
null /* 不为 null 则覆盖 appsettings 中的 SenpacWeixinSetting 配置*/,
register => { },
(register, weixinSetting) =>
{
//注册公众号信息（可以执行多次，注册多个小程序）
register.RegisterWxOpenAccount(weixinSetting, "【盛派网络小助手】小程序");
});

用以上这句也是同样。

模块对应的 .net 版本

• .net 7.0

开发环境

• Visual Studio 2022

缓存环境

• 服务器内存缓存（默认）

[pcvc]

builder.Services.AddSenparcGlobalServices(builder.Configuration) // Senparc.CO2NET 全局注册
.AddSenparcWeixinServices(builder.Configuration); // Senparc.Weixin 注册

var app = builder.Build();

[pcvc]

已自行解决：

builder.Services
.AddMemoryCache()//使用本地缓存
.AddSenparcGlobalServices(builder.Configuration)
.AddSenparcWeixinServices(builder.Configuration)//Senparc.Weixin 注册
.AddOptions();

我也是用的.NET7，请问一下 使用 app.UseSenparcWeixin 这个方法需要引用哪一个命名空间？

[pcvc]

位于程序集 Senparc.Weixin, Version=6.16.3.2, Culture=neutral, PublicKeyToken=null�。
命名空间：Senparc.Weixin�

我也用.NET7，请问一下使用app.UseSenparcWeixin这个方法需要引用哪一个命名空间？

Senparc.Weixin.AspNet
