.net 4.5 - what does this mean?

I have a site that's not working in IE11. I get the _doPostBack error.

I fixed this for IE10 but running a patch from Microsoft.

Now, I'm getting it in IE11:

http://www.hanselman.com/blog/IE10AndIE11AndWindows81AndDoPostBack.aspx

"This whole concept has been long-fixed in ASP.NET 4.5. If you have a .NET 4 app you put .NET 4.5 on it and you're set. We don't sniff like this anymore"

That means install framework 4.5? (I just noticed that fix is for Windows 8.1. I probably have to look for another solution or upgrade my code to 4.5)

That's because IE11 does not report itself the same way
Is there a reason you cannot update .net?

I just asked our hosting server to update .net on our staging server first.

Do I need to upgrade the code to VS2013/4.5 as well? I was planning on doing it in the next couple of weeks. Would it work for now, with VS2010 code that I have?

Have a browse thru
http://msdn.microsoft.com/en-us/library/hh367887%28v=vs.110%29.aspx

and see if there is anything you need to update prior to the upgrade so you are ready for it.

Looked at the list and looks like I'd be fine.

Now, suppose something doesn't work, I can still go back to 4.0, I think. Isn't that in IIS that I can set the application pool ?

No, its an inplace upgrade, once installed there is no going back.

Microsoft
Lets create a browser that doesn't tell anyone its IE10, and breaks .net, then create a fix so it recognises IE10, then we will create IE11 but lets change how it announces itself to the world again so it breaks all your sites again, then lets create .net 4.5 to fix all those sites but lets not give anyone the option of still running their .net 4.0 projects and so on and so on...

Oh boy :)

I'm going to upgrade the code from 2010 to 2013 within the next 2 weeks.
Based on that link, I should be ok, tho.

The code is straight forward; LINQ, stored procs, Listview, upload/download files. Nothing fancy in it.
