Does f# 4.0 support .net 3.5?

Can I use 4.0 compiler to create .net 3.5 dll?

Or the minimal .net version is 4.5?

Also, could the latest version of FSharp.Core be used with .net 3.5?

If you select .NET Framework 4 as the Target Framework in Visual Studio, the only F# version you can pick is F# 3.0:

Visual Studio project properties

If, on the other hand, you select .NET Framework 4.5, the option to pick F# 4.0 becomes available as well.

Based on that, it looks as though .NET 4.5 is the minimum version for F# 4. That's only Visual Studio's view, though, so it may be possible that you can use F# 4 with older versions of .NET using other development tools.

If you look at the NuGet page for FSharp.Core 4.0.0.1 (currently the most recent version), you'll see that it supports these frameworks:

  • .NET 2.0
  • .NET 4.0
  • .NET Portable Profile 7 (portable-net45+netcore45)
  • .NET Portable Profile 47 (portable-net45+sl5+netcore45)
  • .NET Portable Profile 78 (portable-net45+netcore45+wp8)
  • .NET Portable Profile 259 (portable-net45+netcore45+wpa81+wp8)
