1. Visual Studio For Mac Os
2. X Code

If I had to really take a guess here, this is what I'd speculate.

• When comparing Visual Studio vs Project Rider, the Slant community recommends Project Rider for most people. In the question “What are the best C# IDEs?” Project Rider is ranked 2nd while Visual Studio is ranked 3rd.
• Visual Studio is a new member of the Visual Studio family, enabling developers on macOS to build apps for mobile, Web, and cloud with Xamarin and.NET Core, as well as games with Unity. Use Visual Studio to develop apps for Android, macOS, iOS, tvOS, watchOS, Web, and cloud.

In addition, this Visual Studio for Macs will support C# and F# so it will allow developers to create web sites and applications from Macs more easily. For now, what we have is the Microsoft Connect event that is held from November 16 to 18 and possibly where there will be news of the arrival of Microsoft Visual Studio on Mac.

Visual Studio For Mac Os

This is only the first step for Visual Studio Mac. The next will be to begin bringing feature parity to the Mac version (My gut feeling is that VB.NET won't make the leap, but with Roslyn, maybe I'm wrong).

I feel this isn't stated enough. VSCode, albeit made by Microsoft, goes way beyond Microsoft's core interests. Given that you can now enable language support for around 470-ish languages, I don't think that their game here is to be a replacement for anything. I have an even crazier suspicion about what VSCode is really about.

X Code

So if you've lived with Visual Studio for years, you know that it's been COM based for a looonnnnggg time (since inception). I think VSCode serves two interests. The first interest is to bring non-Microsoft users in the fold with the hopes that they may go 'This ain't so bad, maybe I'll give other stuff a try'. I think the second is that they need a playground to figure out how to, excuse me here, 'unfuck' the core architecture of Visual Studio. If they can write suitable replacements for core functionality, let them bake and mature for some time, then BOOM! they can replace the VS components.

Like I said, just a crazy opinion based on what I've seen so far.
