HTTP错误500.30-.net core 2.2中的ANCM进程内启动失败

Question

我正在尝试运行此REST API，但不断出现以下错误：

HTTP Error 500.30 - ANCM In-Process Start Failure

我试图将.net core从2.2.0升级到2.2.5。 2.2.0是Visual Studio的默认版本。我正在Visual Studio 2019中对此进行编码。

我还从以下网站下载了dotnet托管软件包：

https://dotnet.microsoft.com/download/dotnet-core/2.2

我下载了V2.2.5版本并安装了Windows X64的SDK，ASP.NET Core Runtime 2.2.5和.NET Core Runtime 2.2.5。

下面的

是屏幕截图。

及以下是我的dotnet信息的屏幕截图：

尽管下载了所有内容，但我仍然收到错误消息：

HTTP Error 500.30 - ANCM In-Process Start Failure

最后，我将csproj文件AspNetCoreHostingModel更改为outprocesses，然后将错误更改为 处理失败，所以我将csproj更改回原始文件。

当前，我的csproj文件如下所示：

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>

  <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>

  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.2.0" PrivateAssets="All" />

  </ItemGroup>

  <ItemGroup>
    <PackageReference Update="Microsoft.NETCore.App" Version="2.2.5" />
  </ItemGroup>

</Project>
