.NET Framework 3.5 SP1 - rarely used

[tradejockey]

I was looking at add/remove programs under control panel and it was showing .net frameworks above 1.1 i.e (2.0, 3.0 and 3.5 sp1) as rarely used... Is this a cause for concern? 3.5sp1 last used was Aug which is probably the install date...

Have the programmers put in enough guardrails to force the application to use the latest .net? Or does it randomly choose the version?

Also, does .net3.5sp1 come bundled with nt7 install? kinda like the jre with some java programs?

Also, can VS2005 still be used for debug purposes? I understand that CLR: VS2008 -> .net3.5 and vs2010 -> .net4 and VS2005 -> .net2.0 CLR. I did notice one .net2.0 clr error with NT7 in event log. This was perhaps due to VS debugger turning on clr exceptions. Not sure... just asking.

One more thing I noticed is that there are no shortcuts to .net 3.0 or 3.5sp1's configurations under control panel->performance and maintenance->administrative tools. Dont know if this is normal.

I have automatic updates on and get all MS updates.

Please consult MS support regarding the meaning of Windows stats and other details regarding .NET 3.5 SP1.

You likely already have .NET 3.5SP1 installed (see the stats you had been referring to).

VS2005 debugging: You needed to try by yourself.

Does NT 6.5 ...14 run properly with .NET framework 4 Beta 2 ? I'm considering installing VS2010 beta 2, but don't want to cream my NT installation...

Can I install VS2010 without affecting my NT ?

Thx,
