c# - AspNetCoreModuleV2问题.NET Core 3.0

Question

希望有人能帮忙解决这个问题:

我已在 Azure 上部署了 .NET Core 3.0 应用程序，尽管它显示“发布成功”。应用程序未加载(http 500，服务器错误)。Azure 中的“诊断和解决问题”选项卡指向模块“AspNetCoreModuleV2”，如图所示 Azure - Diagnose and solve problems

我已经尝试过:

• 按照此处的建议安装 .NET 3.0 运行时托管 bundle aspNetCore 2.2.0 - AspNetCoreModuleV2 error

• 更改 modules="AspNetCoreModuleV2"至modules="AspNetCoreModule"在 web.config 文件中，但一旦我发布应用程序，该文件就会恢复为其原始值。

• 添加<AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>到csproj但这没有什么区别，所以我删除了它

这是我当前的 csproj文件:

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

  <PropertyGroup>
    <TargetFramework>netcoreapp3.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <Folder Include="wwwroot\" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="3.0.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.0.1" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="3.0.1">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.0.1" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer.Design" Version="1.1.6" />
    <PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="3.0.1" />
    <PackageReference Include="Newtonsoft.Json" Version="12.0.3" />
    <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.1.0-preview1-final" />
  </ItemGroup>

</Project>

这就是我的web.config文件看起来像

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\SportsStore.dll" stdoutLogEnabled="false" stdoutLogFile="\\?\%home%\LogFiles\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
</configuration>
<!--ProjectGuid: 3f1b616a-5c07-4b23-9c86-ec6506dc3fa7-->

顺便说一句，应用程序在本地计算机上运行没有任何问题

非常感谢任何可以为我指明正确方向的帮助。

编辑您的 csproj

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel>
    <AspNetCoreModuleName>AspNetCoreModuleV2</AspNetCoreModuleName>
..

通过这种方式，在 dotnetpublish 期间，TransformWebConfig 任务将您的 web.config 转换如下，这也适用于 Azure WebApp

<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\assembly.dll" hostingModel="OutOfProcess" />
    </system.webServer>
  </location>
</configuration>

在 Azure WebApp 中，HTTP 错误 500.31 - ANCM 无法找到 native 依赖项 错误似乎是由 InProcess 托管模型和模块 AspNetCoreModuleV2 引起的>
