I\'ve recently updated to using VS2013 and Resharper 8.2, (from VS2010 and Resharper 6) and have found a very annoying \"feature\" in that Resharper\'s intellisense
In Resharper Ultimate 2016.1 you can do this :
Resharper => Options => IntelliSense => Completion Behavior => Set Sort Items to Alphabetically
It appears that the glitch was specific to ReSharper version 8.2.1. I have just downloaded/installed the latest release, 8.2.3, and the list of members is once again shown in alpha order.
IntelliSense can be reverted to Visual Studio as follows:
Resharper => Options => IntelliSense => General => Custom IntelliSense => set C# to Visual Studio
No sure how much Resharper benefit I'm losing by doing this - but needs must.
