How to manage NET framework 4.6 version for only one app?

Hello everyone. Since I'm fist time facing this kind of task, I want to make sure everything went smooth because its a production environment.

I googled this for a while and didnt find all the informations I need so if anyone have any experience with this and would be willing please share it.

My question is regarding web server, NET framework version. There are already 3 versions running on IIS server, 2.0, 4.5 and 4.7.

 It's an Windows 2012 (not R2) standard version server hosting like 200 web apps and now one of them need a NET 4.6 to run their application, web config/ Visual studio editing is a customer resonsibility. IIS 8.

1. Can I install NET 4.6 with no automatic impact on other apps?
2. How to set it just for an specific subdomain and leave other as it is?
3. Are there any permission issues needed to be set on app pool?
4. Does it need a restart?

  Thanks in advance!

If .NET 4.7 is installed and working (looks like it is), that covers the functions of .NET 4.6.  You should be fine.

Get .NET Framework Setup Verifier from here:

Then run it and check that all versions are working.

Thanks for your quick response John!

Yes, its says 4.7, "Product verification suceeded".

So 4.6 would be also covered with 4.7 version, do I need to manually set it somewhere on IIS settings for my clients app pool so they can use it or they just need to point it somewhere in web config file?

Did you check and see if V4.6 also verified?  I don't think you can separate the pieces.

So I think .NET is fine and if you need adjustments, that would need to be in the application.
