在RHEL 7中运行ASP.NET Core的问题

Question

我已经在Visual Studio 2017中针对ASP.NET Core 2.2.8 Runtime构建并发布了ASP.NET Core应用程序。当我将（xcopy）部署到RedHat并尝试在Kestrel中运行时，出现以下错误：

Unhandled Exception: System.BadImageFormatException: Could not load file or assembly 'Microsoft.AspNetCore.Server.Kestrel.Core, Version=2.2.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The module was expected to contain an assembly manifest.

这是我的.csproj文件中的内容：

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
    <Platforms>x64</Platforms>
    <MicrosoftNETPlatformLibrary>Microsoft.NETCore.App</MicrosoftNETPlatformLibrary>
  </PropertyGroup>
  <ItemGroup>                                                                            
    <Content Update="appsettings.json;web.config">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </Content>
  </ItemGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" Version="2.2.8" />
    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.2.8" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.2.0" PrivateAssets="All" />
  </ItemGroup>
  <ItemGroup>
    <PackageReference Update="Microsoft.NETCore.App" Version="2.2.8"/>
  </ItemGroup>
</Project>

我在RedHat文档中发现RedHat不提供ASP.NET Core 2.2 Hosting Bundle。相反，RedHat建议执行自包含的构建并将所有文件（大约400个）复制到您的应用程序文件夹中。 RedHat通过将Hosting Bundle包含在.NET Core RPM中，用3.0解决了这一问题。

ASP.NET Core共享框架在RHEL上不可用。部署的ASP.NET Core应用程序必须包括ASP.NET Core软件包。
