Is there any noticable performance gain, after installing the application vs while you are debugging it in Visual Studio?
I am pointing to C# and WinForms….I know it depends on type of data and controls and processes in the application, but would like to know if there is any.
Short answer: Test it.
Long answer: Yes, there is a noticeable performance difference. However, given that most developer’s machines are built like battle tanks, what is slow on your machine, will probably be even slower on a standard corporate desktop (even if it’s no longer running in debug mode).
The only way to know for sure is to try deploying your application to a target machine and measuring the performance.
