Do I still need ObjectARX SDK for AutoCAD 2020?

[djbounds]

Hello, I haven't programmed in .Net since AutoCAD 2012.  

I'm watching some tutorials to refresh my cobwebs.  I will be using Visual Studio 2015 Express. I was wondering if I still net objectARX.   I was trying to find it on the Autodesk website but can't seem to find it.   The tutorial is about 4 years old and the website has changed.

This forum is meant for ObjectARX C++, not for AutoCAD .NET APIs. But here we go:

Technically, for doing AutoCAD .NET API, you DO NOT NEED TO have ObjectARX SDK. VisualStudio (I'd go with latest VS2019, which also has free version as any earlier versions, so why being stuck with VS2015?) and installed AutoCAD are all you need to get your hands dirty.

ObjectARX SDK for .NET programming is just something"nice-to-have": 

1. You get stripped version of AutoCAD .NET reference assemblies (accoremgd/acdbmgd/acmgd.dll), which is development/design use ONLY;

2. You get API documentation

3. You get tons of sample code

4. You get an AutoCAD .NET add-in wizard that can be added into Visual Studio's new project start page (however, I'd recommend not use at all).

Thank you for the info.  This stuff is good to know, since I haven't coded in .NET for AutoCAD or Inventor since 2012.

I didn't know this forum wasn't for .net, the forum just says ObjectARX.   I am following a tutorial on Linda .com where the guy uses both the ObjectARC SDK and .net 2015 for AutoCAD 2018 - trying to get back in the game., so that's why I asked.
