c# - Different NuGet package based on operating system

I have a test project in dotnet 2.1 that needs to work across multiple platforms (specifically, windows and linux-based systems) as well as access DB2 databases.

IBM provides separate NuGet packages for different operating systems:

  1. IBM.Data.DB2.Core
  2. IBM.Data.DB2.Core-lnx
  3. IBM.Data.DB2.Core-osx

How can I specify in my .csproj file that I want to use different packages based on the operating system?

Passing in the RuntimeIdentifier (dotnet publish ... -r linux-x64) is possible, but I am unsure how to leverage that information inside the csproj. I am also not opposed to using the Choose/When construct, but don't know how to infer what system is trying to build the project.

Use IsOsPlatform(platform) MSBuild property function:

<PackageReference Include="NetVips.Native.linux-x64" Version="8.9.1" Condition="$([MSBuild]::IsOsPlatform('Linux'))" />
<PackageReference Include="NetVips.Native.osx-x64" Version="8.9.1" Condition="$([MSBuild]::IsOsPlatform('OSX'))" />
<PackageReference Include="NetVips.Native.win-x64" Version="8.9.1" Condition="$([MSBuild]::IsOsPlatform('Windows'))" />
