I have a short deadline to test a desktop application. Which record and playback software can be used for desktop application (developed on .NET)?
A lot depends what kind of app is this. WPF, UWP, WinForms or Win32? All of them might be developed in .NET.
There is a lot of tools (mostly paid). I would suggest Ranorex, as this is the easiest (but not the cheapest one). Then there is Coded UI, for which you need Visual Studio Enterprise Edition (which cost more than a lot).
At last there is a free and my favourite tool, but you need to write some of the automation code by yourself (i've seen also recording tools there, but they can't do everything). It's done my Microsoft and it's called WinAppDriver and should be combined with Appium
