Problem:
Getting annoyed when working in Visual Studio 2017 and each time you you open a work item from Team Explorer pane, it opens it in the web?
Well according to recent conversations I have had, it appears that not to many people know about the ability to set the behaviour.
Solution:
By default, VS2017 will open the work items in the browser, but there is a way to change it. When you open Visual Studio and select the Tools > Options from the menu. Find the "Work Items" section and under General you can change the behaviour.
Setting it to "Visual Studio (compatibility mode)" will open the work items in Visual Studio as before.
Be warned though, this is option is due to be removed in the next major release of Visual Studio where the default behaviour will be to open the work item in the browser. So use it while you can
