As you can guess from the title, the outlining with regions finally made me sick.
I remember reading in comments somewhere that it is possible to have a macros to perform this task. Since I haven't ever written a single macros fro VS, I ask for community assistance.
How?
For VB,
Tools –> Options –> Text Editor –> Basic –> VB Specific –> Enter outlining mode when files open.
For C#,
Tools –> Options –> Text Editor –> C# -> Advanced -> Enter outlining mode when files open.
For C/C++,
Tools –> Options –> Text Editor –> C/C++ -> Formatting -> Enter outlining mode when files open.
