I need to compile rather old .NET Framework application targeting .NET Framework 3.0.
When I open the solution in Visual Studio 2015 or 2017 (no difference), it suggests to upgrade to newer version or to download targeting pack for 3.0 from this page:
https://www.microsoft.com/net/download/visual-studio-sdks
But from what I see, there is no targeting pack for .NET Framework 3.0?
Could you please help me, how can I solve it? I don't want to upgrade right now.
