转换 netcore2.2 -> netstandard2：未定义运行命令属性

Question

我正在将我的 netcore2.2 应用程序转换为 netstandard2.0;net472。

这是我的主要项目的 csproj 文件：

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

  <PropertyGroup>
    <TargetFrameworks>netstandard2.0;net472</TargetFrameworks>
    <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
    <Platforms>AnyCPU;x64</Platforms>
    <StartupObject></StartupObject>
    <ApplicationIcon />
    <OutputType>WinExe</OutputType>
    <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">
    <PlatformTarget>AnyCPU</PlatformTarget>
  </PropertyGroup>

  <ItemGroup>
        <PackageReference Include="JWT" Version="5.3.1" />
        <PackageReference Include="Microsoft.AspNetCore" Version="2.2.0" />
        <PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer" Version="2.2.0" />
        <PackageReference Include="Microsoft.AspNetCore.CookiePolicy" Version="2.2.0" />
        <PackageReference Include="Microsoft.AspNetCore.Hosting.WindowsServices" Version="2.2.0" />
        <PackageReference Include="Microsoft.AspNetCore.HttpsPolicy" Version="2.2.0" />
        <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.2.0" />
        <PackageReference Include="Microsoft.AspNetCore.Session" Version="2.2.0" />
        <PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="2.2.0" />
        <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="2.2.0" />
        <PackageReference Include="Microsoft.Extensions.Logging.EventLog" Version="2.2.0" />
        <PackageReference Include="Microsoft.Extensions.Options" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.2.0" PrivateAssets="All" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Proxies" Version="2.2.6" />
    <PackageReference Include="Microsoft.IdentityModel.Tokens" Version="5.5.0" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.2.3" />
    <PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="2.2.0" />
    <PackageReference Include="swashbuckle.aspnetcore" Version="4.0.1" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\mvaasa.repository\mvaasa.repository.csproj" />
    <ProjectReference Include="..\mvaasa.services\mvaasa.services.csproj" />
  </ItemGroup>

</Project>

这是我的 Application Settings:

每当我尝试 Start Debugging (IIS Express) 时，都会弹出以下错误消息：

如何设置？

更新

我尝试将 OutputType 设置为 Exe，如下所示：

<OutputType>Exe</OutputType>

.NET Standard 不是将生成运行nable 程序集的目标框架。以 .NET Core 为目标，以便能够运行在实际运行时间。

定位 netstandard2.0 仅对库有用，对您想要运行的程序无用。

当您以多个框架为目标时，还要确保将预期的运行时间传递给运行 on:

dotnet run -f netcoreapp2.2
