ASP.NET Core 应用程序部署到自己的服务器错误

Question

使用 Visual Studio 2019 发布应用程序后，切换到我的应用程序的索引页时出现错误。

我有这个例外：InvalidOperationException：找不到包“Microsoft.AspNet.WebApi.Client”的编译库位置

有异常的堆栈跟踪：

我尝试了所有关于编写新配置的方法，通过更改 csproj 文件，但没有任何帮助。

有 web.config 文件：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false">
      <environmentVariables>
        <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Production" />
      </environmentVariables>
    </aspNetCore>
  </system.webServer>
</configuration>

有我的 csproj 文件：

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

<PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
    <DockerDefaultTargetOS>Linux</DockerDefaultTargetOS>
    <GeneratePackageOnBuild>false</GeneratePackageOnBuild> 
    <!-- Fix for"System.InvalidOperationException: Cannot find compilation library location for package 'Microsoft.AspNet.WebApi.Client'" -->
    <MvcRazorExcludeRefAssembliesFromPublish>false</MvcRazorExcludeRefAssembliesFromPublish>
</PropertyGroup>

<ItemGroup>
    <Compile Remove="Migrations\***.cs" />
    <Compile Remove="Migrations\***.cs" />
</ItemGroup>

<ItemGroup>
    <PackageReference Include="Microsoft.AspNet.WebApi.Client" Version="5.2.7" />
    <PackageReference Include="Microsoft.AspNetCore.App">
        <PrivateAssets Condition="'%(PackageReference.Version)' == ''">all</PrivateAssets>
        <Publish Condition="'%(PackageReference.Version)' == ''">true</Publish>
    </PackageReference>
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.2.0" PrivateAssets="All" />
    <PackageReference Include="Microsoft.Extensions.DependencyModel" Version="3.1.1" />
    <PackageReference Include="Microsoft.VisualStudio.Azure.Containers.Tools.Targets" Version="1.7.9" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="2.2.6" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.2.4" />
</ItemGroup>

</Project>

请帮忙，我不知道该怎么做才能解决这个异常。

Answer 1

尝试将其添加到您的 csproj 文件中 -

<MvcRazorExcludeRefAssembliesFromPublish>False</MvcRazorExcludeRefAssembliesFromPublish>

根据https://github.com/dotnet/roslyn/issues/37760#issuecomment-518783156

Answer 2

我相信这与您的发布设置有关。 有问题的文件没有发送到服务器。 您可以执行以下操作：

在“设置”下的“发布”窗口中，您可以选择“ Deployment Mode = Self contained

替代解决方案 - 如果这是从 1 站点升级到 .NET Core 2

（来源： 已发布的 ASP.NET 核心站点上的错误：找不到包“Microsoft.AspNet.WebApi.Client”的编译库位置）

• 您可能需要停止应用
• 清除 wwwroot 文件夹 - 旧版本可能会遗留旧 DLL。
• 重新上传/部署
