when i built release project, and when im double click on .exe file of compiled project it tooks around 2 minutes to open, , my project only 173Kb size.I checked .exe with ANTS PERFORMENCE, it says that much time takes "executable hidden methods without source" Winforms contains around 20 textboxes with 8000 chars on each.Those textboxes hided out of the form and i made them small size hided into GroupBoxes. If i will disable them or make them invisble, and enabled them when code needs it, will it help? Or any another solution?

What I have tried:

Do you have any references to other not standard dll's ?

What happens if you disable/remove this dll ?

Will try, so you think its only about using dll's? It's not about massive chars in textboxes?

You should profile your application: Beginners Guide to Performance Profiling

Do you check for existing serial ports by trying to open them within a loop?
That will take a long time for ports that does not exist.

so the text boxs that you put on the form which you are using to store values I assume are causing the issue?

Why not convert these into variables global in your code so you can keep the information in there? they are just string values correct?

The initialization of these 20 8000 character text boxes are causing your issue most likely.

Thanks
