Yep you will need to install all previous framewoks to install 4.6.2. This isnwhat winetricks does anyway.
This is not 100% correct. The .NET 4.5 installer contains some files in an .msu package. Wine Staging provides a basic WUSA implementation than can handle those files and you can install 4.5 directly without first installing any older .NET versions. The only problem is that .NET 4.5 does not support XP any more. If you install 4.0 first in XP mode, you get some additional libraries that are only used for XP, while installing .NET 4.5 directly with Wine Staging will only provide the windows 7 libraries. You will for example notice that .NET 4.5 starts using UIAutomationCore.dll when installing it directly with Wine Staging. On the other hand, running 4.5 with XP libraries from 4.0 is not supported by MS and might introduce new bugs. When the windows 7 support of Wine is getting better, using the windows 7 dlls should be the better choice.
How do you solve this in wine, the issue of outdated Root CAs that is? Can they be shipped with Wine?
So far Wine does not contain any CAs and expects the host system to provide them.
