  • Latest version: 1.0.1
A community answer to Microsoft’s decision to single out net35 by excluding it from the https://www.nuget.org/packages/Microsoft.NETFramework.ReferenceAssemblies/ package. This package provides the .NET Framework 3.5 reference assemblies so that net35 projects can be built using the dotnet CLI. Example project that targets multiple frameworks: <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <TargetFrameworks>net35;net40;netstandard2.0;netcoreapp3.0</TargetFrameworks> </PropertyGroup> <ItemGroup> <PackageReference Include="Microsoft.NETFramework.ReferenceAssemblies" Version="1.0.0" /> <PackageReference Include="jnm2.ReferenceAssemblies.net35" Version="1.0.1" /> </ItemGroup> </Project>
