Hello,

please help with the next issue. I have an application (wpf) which was done via Visual studio 2013 for windows desktop.

My window has tabs, and program is hanged when user try to switch from one tab to another. Please, advise what I should to try to fix that issue.

I even do not know what to do with that. I tried just simple recompilation, but it did not help at all.

DO you have the same version(s) of the .NET framework installed on each machine? IS the app targeting a framework that is installed on the W10 and Server machines? You can check (and set) what version to target when building it (via the project properties pages.)

Check the Event Log on your Windows 10 and Windows Server machine. It can provide you with more information.

Your question isn't answerable. We have no idea what your code is doing upon a tab switch, what it's supposed to be doing, what code you've written, ... NOTHING AT ALL to go on.

The only possible advice is to use the debugger to see what your code is doing.
Preferably on a system where your app hangs.

There is a tool that allow you to see what your code is doing, its name is debugger. It is also a great learning tool because it show you reality and you can see which expectation match reality.
When you don't understand what your code is doing or why it does what it does, the answer is debugger.
Use the debugger to see what your code is doing. Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

Debugger - Wikipedia, the free encyclopedia[^]
Visual Basic / Visual Studio Video Tutorial - Basic Debugging - YouTube[^]
Visual Basic .NET programming for Beginners - Breakpoints and Debugging Tools[^]

The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.
