.NET 4.5 support is done
i create the .NET 4.5 assemblies for NetOffice today and the upload is currently in progress.
.NET 4.5 may an in-place update but secure is secure hm 
the 1.5.1 [RC+Office 2013 Support] release includes the assemblies/examples/tutorials in .NET 4.5
btw: CoClasses like Excel.Application has static methods now for easy access to all the running objects. as example:
Dim app as Excel.Application = Excel.Application.GetActiveInstance()
use the GetActiveInstances() method to get all running objects.
All about the improved well known types in Office 2013
A lot of well known types in office 2012 and further has more functionality in office 2013. more methods, more properties and so on.
NetOffice has 6 new tables in the documentation area. you can see all new 2013 functionalities for existing types from 2012 and further.
Some of the new properties sounds good i find. 20 new enum members in Office.MsoPresetTextEffect and something more.
Is my code ready for Office 2013?
in my last blog i show you the new types in office 2013. another good question is the compatibility of existing code, in other words, is my code good enough for office 2013? good news: the office 2013 COM Api is full compatible to the previous version. i find no changed types/methods/properties/enums in office or any other missing feature. i’m suprised 
Whats new in Office 2013?
The consumer preview for Office 2013 is done!
