What version on .net framework on a new server?

[Jobos]

I'm setting up a new sims server and in the middle of the windows updates. What version of .net framework does a sims server need? I understand it needs v3.5 but I see v4.6.1 is out. Would v4.6.1 replace v3.5 or are they both needed?

3 and 4 are separate (Remember 3 isn't via updates on 2012r2 it's a feature addon). 4.x is the default in 2012r2 anyway

 

However I'd avoid 4.6.1 and stick with 4.5.2 if you can, there was some major bugs with it and while they may have been patched since it's nothing really needing it yet so personally I'd hold on 4.5.2

Thanks for the info.

SIMS does require .NET 4.5 (I think), but I have .NET 4.6.0 (the original release) installed on all servers and there's no issues. I can't remember if it's 4.6.1 or 4.6.2 that caused problems with Active Directory/Group Policy (top of my head)!

Yes I was reading a thread about 4.6.1 causing problems with clients but nothing was said about servers so I guess the server version was bug free.

Well all newer .NET releases are the same for all supported OSes 32/64Bit - as I say, I have .NET 4.6.0 on a few Windows Servers running SIMS and it works fine.

 

Windows 10 itself also includes .NET 4.6 as standard. I presume Redstone will probably include .NET 4.6.1 or .NET 4.6.2, who knows!?

Servers were one of the main bits it did break It nuked Exchange servers, broke mailboxes, broke WSUS, broke Sharepoint etc https://support.microsoft.com/en-us/kb/3047761 even made a KB because it broke a lot

 

Like I said it might be fixed, but is it worth the risk currently?

Exchange 2013 CU13 added support for 4.6.1 I think (it certainly works with mine) but I've kept it off of my other servers for the moment

I run this a part of a script to ensure that SQL will install on the server. It installs 3.5 if it hasn't been installed as part of the Server 2012 build. You can run both from a CMD prompt.
