Where do I download the .net framework sdks [Answered]

I have a rather old program I am trying to run and I need the sdk for 4.5.2 but on the https://dotnet.microsoft.com/en-us/download/visual-studio-sdks site the framework developer pack's don't install in the same way as the current sdks, where do they install and how do I get it working?

actually the assembly has its version as [assembly: AssemblyVersion("1.0.0.0")] which seems even older than what I want, it has been a while since I have used framework

assembly version isnt linked to what .NET version it was made with

ah that is old

if you need 4.5.2: https://www.microsoft.com/sv-se/download/details.aspx?id=42642

ah ok thanks
