Unreal 升級錯誤 The type or namespace name 'Tools' could not be found
升級時若出現 The type or namespace name 'Tools' could not be found (are you missing a using directive or an assembly reference?) 可以參考此方法

Unreal 專案從 4.27 升級到 UE 5.0 以上,若出現以下錯誤
⛔
The type or namespace name 'Tools' could not be found (are you missing a using directive or an assembly reference?)
找到以下程式碼
using Tools.DotNETCommon;
改為
#if UE_5_0_OR_LATER
using EpicGames.Core;
#else
using Tools.DotNETCommon;
#endif
