.NET Platform Conditional Tags in .csproj

Mar 8, 2021 | 1 min | #dotnet #csharp

In addition to symbols you can use in code, one can also use TFMs in .csproj files for instance to decide which references to use depending on target framework, like so:

1   <ItemGroup Condition="'$(TargetFramework)' == 'netstandard1.4'">
2      <PackageReference Include="System.Reflection.Emit.Lightweight" Version="4.7.0" />
3   </ItemGroup>

Here is the list of all the TFMs known today:

Target Framework	TFM
.NET 5 (and .NET Core)	netcoreapp1.0; netcoreapp1.1; netcoreapp2.0; netcoreapp2.1; netcoreapp2.2; netcoreapp3.0; netcoreapp3.1; net5.0
