在 Azure 中托管 Asp.Net Core 3.0：HTTP 错误 500.31 - ANCM 无法找到本机依赖项

Question

我正在尝试在 Azure 中托管 ASP.NET Core 3.0 API：

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

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

  <PropertyGroup>
    <IsPackable>false</IsPackable>
    <NeutralLanguage>en-US</NeutralLanguage>
    <LangVersion>latest</LangVersion>   
  </PropertyGroup>  

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Mvc.Versioning" Version="3.*" />
    <PackageReference Include="Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore" Version="3.*" />
    <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="3.*" />
    <PackageReference Include="Microsoft.Extensions.Diagnostics.HealthChecks.EntityFrameworkCore" Version="3.*" />
  </ItemGroup>       

</Project>

但是当我运行 de application 时，我得到：

HTTP Error 500.31 - ANCM Failed to Find Native Dependencies

Common solutions to this issue:
The specified version of Microsoft.NetCore.App or Microsoft.AspNetCore.App was not found.
Specific error detected by ANCM:
It was not possible to find any compatible framework version The specified framework 'Microsoft.AspNetCore.App', version '3.0.0' was not found. - The following frameworks were found: 2.1.12 at [D:\Program Files (x86)\dotnet\shared\Microsoft.AspNetCore.App] 2.1.13 at [D:\Program Files (x86)\dotnet\shared\Microsoft.AspNetCore.App] 2.2.6 at [D:\Program Files (x86)\dotnet\shared\Microsoft.AspNetCore.App] 2.2.7 at [D:\Program Files (x86)\dotnet\shared\Microsoft.AspNetCore.App] You can resolve the problem by installing the specified framework and/or SDK.

我错过了什么？

Answer 1

目前的情况是 ASP.NET Core 3.0 随处可用（但不是 SDK）。

尽管如此，我（似乎是随机的）得到了一个

HTTP Error 500.31 - ANCM Failed to Find Native Dependencies

直到我意识到web.config通过设置stdoutLogEnabled为激活登录true 而不调整stdoutLogFile到\\?\%home%\LogFiles\stdout（如Azure 应用服务和 IIS 上的 ASP.NET Core 疑难解答中所建议的）是导致此错误消息的原因。

我花了几个小时才意识到这种因果关系。
