应用程序在 Azure 上部署为(32 位，.NET Core 2.2)应用服务。当使用标准 AspNetCoreModule 而不是支持 InProcess 托管模型的较新的 AspNetCoreModuleV2 时，它工作正常。

当使用新的InProcess托管模型时，实际错误是

Could not find inprocess request handler. Captured output from invoking hostfxr: Invalid runtimeconfig.json [D:\home\site\wwwroot\Foo.Api.runtimeconfig.json] [D:\home\site\wwwroot\Foo.Api.runtimeconfig.dev.json]

Foo.Api.runtimeconfig.json 位于 wwwroot 位置

{
  "runtimeOptions": {
    "tfm": "netcoreapp2.2",
    "framework": {
      "name": "Microsoft.AspNetCore.App",
      "version": "2.2.0"
    },
    "configProperties": {
      "System.GC.Server": true
    }
  }
}
