Issue type: Bug
Clarity: Mostly clear
Activity status: Stale
Tech stack: csharp, powershell
Domain: database, tooling

Research direction

Start with the provided csproj and the Package Manager Console Scaffold-DbContext command, then compare the hostpolicy.dll failure with linked core-setup issue #4865. Done means the command works for RuntimeIdentifier win7-x86 without the reported hostpolicy.dll loading error.

@Suchiman
With a csproj looking like

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <RuntimeIdentifier>win7-x86</RuntimeIdentifier>
  <PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="2.2.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="2.2.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.2.0">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers</IncludeAssets>
    </PackageReference>
  </ItemGroup>

Trying to issue following command on the package Manager console
Scaffold-DbContext "Server=..." Microsoft.EntityFrameworkCore.SqlServer -OutputDir Database -Force
will result in this error being generated:

Failed to load the dll from [Project\bin\Debug\netcoreapp2.2\win7-x86\hostpolicy.dll], HRESULT: 0x800700C1
An error occurred while loading required library hostpolicy.dll from [Project\bin\Debug\netcoreapp2.2\win7-x86\]
