    Upgrade Umbraco 4.7.1 from .Net 4.0 Framework to 4.5?

    Hi,

    I am running into problems with .Net 4.0 and Internet Explorer 11. There is a patch from Microsoft, but everybody says to upgrade from .Net 4.0 to .Net 4.5.

    Does anybody know if I will have a problem with my old 4.7.1 running .Net 4.5 ?? There is no coming back after installing the update, so I'd rather avoid trial and error.

    I am currently developing a new website in Umbraco v6.1.6, so I don't really wanna waste time upgrading the old core to a new version, as my old developer told me that it couldn't be done easily.

    I hope somebody can help me :-)

    Best regards
    Jimmy Dan Mortensen

    Do you really need to upgrade to .NET 4.5? If you're having problems with .NET 4.0 and IE11 this patch should also help: http://support.microsoft.com/kb/2836939

    That is the patch I am talking about. My hosting-company says it is installed, but it is still not working. So after a little searching on the net, everybody else is saying to upgrade to 4.5

    Hi Jimmy
    What kind of issues are you having?

    I would not recoomend upgrading the framework since I'm not sure if it will just work or not. I can imagine that all the umbraco dll's should be compiled against .net 4.5 in order to work and that would require you made a fork of the code and did it yourself if I remember correctly (Somebody please correct me if I'm wrong).
    Perhaps some of the suggestions in this post can help you? http://our.umbraco.org/forum/developers/extending-umbraco/46529-umbraco-47-member-login-not-works-in-IE11 - Have a look at the suggestions from Dennis Aaen and Bob Baty-barr.

    Jan ... You are my god :-)

    It worked :-) I just copy/pasted the browser-file, and deleted web.config and uploaded it again (to get the app to reset) and it now works.
