How to fix the "Building x action(s) started" time problem Visual Studio 2022

Question

Hello, I'm reaching out for some assistance! I am a student studying video game development, primarily using Unreal Engine. Unfortunately, I'm facing challenges working from home due to the excessive time spent on building/compiling. I have the latest version of Visual Studio Community 2022 (17.9.1) installed and a powerful computer (16 GB RAM, RTX 2070, Ryzen 7 2700X). Despite this, every C++ modification takes more than 20 minutes to build. It's becoming impossible for me to make progress, and I have an upcoming project presentation. I've searched extensively online and through previous Microsoft support tickets but haven't found a solution. If anyone has any ideas, I'd greatly appreciate the help. I can provide a screenshot showing where the building process is consuming a significant amount of time—it doesn't initiate until after a prolonged delay. Thank you!

Hi @Florent Cazin, 

Welcome to Microsoft Q&A! 

You can try the following from the similar issue:

1. Uninstall Visual Studio Completely
2. Add modules “Desktop development with C++” and “.NET desktop development”, and also “Game development with C++ (for Unreal)”
3. IMPORTANT: On Insallation details: remove IntelliCode (not sure, just tried it)
4. Click Install
5. Open Visual Studio: Tools > Text Editor > C++ > Intellisense, disable both suggestions tickbox (Some forum answers suggest Intellisense might be the issue)
6. Open Unreal Project, compile once (maybe longer), click Tools > Refresh VS Project, save and restart try if compiles faster this time.
7. Else, Close Unreal & Visual Studio, go to project folder delete SIB folders - Saved, Intermediate, Binaires
8. Go to the project folder, right-click PROJECTNAME.uproject file, and select “Generate visual studio project files”
9. Wait and double click open .uproject file (or from select project window), another dialog box displays - click OK to generate new files
10. In UE Editor, select Tools > Open visual Studio (Keep VS open), try compiling now, (and note that first time of adding new C++ file will take some time to compile)

If it doesn’t work, please report it in dedicated Unreal Engine forum. Thanks for your understanding! 

Sincerely, Anna
