将.NET Core 3.0 Web应用程序从IIS Express迁移到IIS时遇到问题

我已经在服务器上开发了一个针对.NET Core 3.0的Web应用程序。该项目基于Visual Studio 2019的ASP .NET Core Web应用程序模板。

我选择了ASP.NET Core 3.0，并指定该应用程序将实现单个用户帐户（身份）。

发展一直很好。我更改了连接字符串，以便在我的应用程序数据库中构建身份表。我已经开发了几个星期，在IIS Express中运行和调试。

确定，现在是时候进行部署了。我在目标服务器上设置了Web Deploy，创建了部署模板并发布。该Web应用程序是在目标服务器上创建的。

但是，我收到了运行时错误：

HTTP错误500.30-ANCM进程内启动失败

Windows事件日志中的诊断将我指向特定的行号，即Startup.cs中的第77行

app.UseRouting();

app.UseAuthentication();
app.UseIdentityServer();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        name: "default",pattern: "{controller}/{action=Index}/{id?}");
    endpoints.MapRazorPages();
});

因此，我退出了目标部署，以查看是否可以在本地开发工作站上的IIS上运行该应用程序。我创建了一个名为cashflow的应用程序，并将其映射到c：\ inetpub \ cashflow。

我创建了一个基于文件的部署，并看到所有应用程序文件都复制到c：\ inetpub \ cashflow中。

我浏览到http://localhost/cashflow，并得到完全相同的错误：

HTTP错误500.30-ANCM进程内启动失败

这是我在Windows事件日志中找到的内容：

抱歉，巨大的堆栈跟踪。我认为输出中最相关的项目是对第77行失败的引用。

，位于C：\ Users \ Yossi \ source \ repos \ Cashflow \ Startup.cs：line 77中的Cashflow.Startup.Configure（IApplicationBuilder应用程序，IWebHostEnvironment env）

我想我缺少支持app.UseAuthorization（）;必需的重要内容。你能帮我这个忙吗？谢谢！
