You can copy the plugin from 5.4. It isnt hard at all. Takes 5/10 mins. All the info use to be on the marketplace but now Fab has replaced it it appears to have been lost.
- Go to the location of your engines (Usually c://Program Files//Epic Games//UE5.4)
- Inside the following folder take a copy of the plugin, Engine//Plugins//Marketplace//VisualStudioTools
- Create the same dir structure (Engine//Plugins//Marketplace) in the UE5.5 code and paste the folder you just copied.
- Inside your project open the .uproject file with notepad and set VisualStudioTools to false. (This is the new requirement I think as I didnt have to do this from 5.3 to 5.4)
- Inside your project is the Source directory. Inside there are 2 file {ProjName}.Target.cs and {ProjName}Editor.Target.cs, open both with notepad and change the IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_5;
And you should be good to go!
