Asp.net 4.0 was not registered by VS 2010 after installing VS2015

Question

Getting this error when opening a VS 2010 project after installing VS 2015 RTM:

Asp.Net is not registered with the webserver, you need to manually configure your webserver for Asp.net 4.0.

aspnet_regiis -i

Does not help. The project still works and debugs fine, so this is really a nuisance, but does anyone know of a fix?

Also, VS2010, VS2013, and VS2015 seem to coexist pretty well so far.

Our devs have the same issue with VS2010 after installing vs2015 and found a solution that worked when aspnet_regiis doesn't.

Microsoft is offering an update to resolve this issue: https://support.microsoft.com/en-us/kb/3002340
