ASP.NET Web的 Razor Pages应用，配置热重载，解决.NET Core MVC 页面在更改后不刷新

Razor Pages应用，修改页面查看修改效果，如果没有热重载，改一句话跑一次，这个活就没法干了。

1、VS2022中的NuGet中安装RuntimeCompilation

Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation

需要配套你的.net sdk版本，我这里用的是6.0，所以这个也用了6.0.0。

2、找到你的Properties\launchSettings.json

主要是这句话"ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation"，配置在

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:5955",
      "sslPort": 44378
    }
  },
  "profiles": {
    "chocolate": {
      "commandName": "Project",
      "dotnetRunMessages": true,
      "launchBrowser": true,
      "applicationUrl": "https://localhost:7103;http://localhost:5138",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development",
        "ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation"
      }
    },
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}
