I've got a solution originally developed under VS2013 which targets .NET Framework 4.0 because it must run on XP machines as well as w7, w8, and w10. When I open the solution in Rider, I get this warning:
.NET Framework Not Installed: Download and install .NET Framework 4 Developer Pack
So I downloaded and ran the installer but got a microsoft message that said 4.0 was already part of the OS (I'm running w10).
Microsoft .NET Framework 4 is already a part of this operating system. You do not need to install the .NET Framework 4 redistributable. <A HREF="http://go.microsoft.com/fwlink/?LinkId=164207">More information</A>.
Same or higher version of .NET Framework 4 has already been installed on this computer.
So I went ahead and built the solution and ran the exe on w10, w7 32 bit, and XP and it seems to run fine. Is the Rider warning a known issue? I notice when I create a new C# solution in Rider, it will not show .Net 4.0 as a selectable target framework, so it seems that my workaround would be to create the solution in VS 2013 and then continue the development in Rider?
