dotnet run 挂起/卡住

Question

razor web 应用程序无法再在我的计算机上启动。

构建命令dotnet build按预期工作，但dotnet run在第一次警告后卡住了。

C:\dev\mywebapp>dotnet run
Building...
C:\dev\mywebapp\Pages\Admin\Orders\TraderOrderList.cshtml.cs(101,17): 
     warning CS0219: The variable 'orderId' is assigned but its value is 
                     never used [C:\dev\mywebapp\MyWebApp.csproj]

C:\dev\mywebapp\Pages\Index.cshtml.cs(23,24): 
     warning CS0414: The field 'IndexModel._currentAd' is assigned but its value is
                     never used [C:\dev\mywebapp\MyWebApp.csproj]

--- after here it is stuck no more output and i stopped it after about 3 minutes

我尝试了什么？

• 我创建了一个新项目c:\dev\webtemp>dotnet new webapp -o HelloWebApp
• 并用 运行它c:\dev\webtemp\HelloWebApp>dotnet run。所以这按预期工作。

我在 stackoverflow 上搜索了其他问题，但没有遇到同样的问题。

问题

• 如何缩小问题范围？
• dotnet run 命令的日志文件在哪里？

点网--信息

为了简洁起见，下面的某些路径已被替换

<path-to-AspNetCore.App>	C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App
<path-shared-NETCore>	C:\Program Files\dotnet\shared\Microsoft.NETCore.App
<path-shared-WindowsDesktop>	C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App

运行dotnet --info回报

更新 - 使用另一个分支返回 404

我确实更改了分支并dotnet run到达了 localhost 启动的部分。

info: Microsoft.Hosting.Lifetime[14]
      Now listening on: https://localhost:7178 info: Microsoft.Hosting.Lifetime[14]
      Now listening on: http://localhost:5057 info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down. info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Development info: Microsoft.Hosting.Lifetime[0]
      Content root path: C:\dev\mywebapp\

但它返回http 404

404 未找到

服务器找不到所请求的资源。...

服务器还可以发送此响应而不是 403 Forbidden，以向未经授权的客户端隐藏资源的存在。

我尝试了几个不同的网址，但每个剃刀页面都失败了（404）。只有wwwroot下的静态html页面有效(200)

小路	网址	结果
C:\...\wwwroot\index.htm	https://localhost:7178/index.htm	200
C:\...\Pages\info.cshtml	https://localhost:7178/privacy	404

几天前我遇到了类似的问题。

就我而言，我使用 NLog 进行日志记录。nlog.config我已经输入了所有必要的代码和配置，但忘记在我的项目中创建该文件。缺少文件nlog.config导致应用程序挂起。
