How to convert Qt code in to C#(.Net).
How to convert Qt code in to C#(.Net). I want to move the GUI part of my project from QT to some other language but want to call C++ method & function from GUI part.Please suggest the better way.
@prabhat If you don't want to use Qt for your GUI you will need to rewrite your GUI. I don't think there is an easy way to convert C++ code which uses Qt into C# using WPF (I assume here you want to use WPF in C#?).
But you actually could simply use C++ in .Net with Qt as Qt supports that combination.
@jsulm thank you so much for your reply. Could you suggest C# or UWP which will be better and how i can call third party application written in c++ using c#.
C# or UWP which will be better
These are two different things:
C# is a programming language
UWP (Universal Windows Platform) is an environment for applications.
So, not sure what you're asking.
"and how i can call third party application written in c++ using c#" - this is unclear. Do you start an application written in C++ in C# (this is possible)? Or do you want to use C++ code in your C# application? And again: you can use C++ to write Qt apps for UWP.
@jsulm due to GPL license issue i do not want to use Qt. I have one projcet that is developed in c++ and UI part is in QT. Now I just want to replace QT (UI) part with C# but C++ functionality will remain same.

Don't know what you mean. Nearly all of Qt (all that you should typically be using) is LGPL rather than GPL license. I can't believe that whether you write your code in C++ or C# will make any difference to licensing requirements, why do you think it would? You won't be able to convert the whole of the Qt code base from C++ to C#, and even if you did I don't think that would obviate licensing requirements, you can't take source code with a license and then hand-translate it to a new language and expect thereby to be excused from licensing considerations.
BTW, https://github.com/ddobrev/QtSharp is still the most supported attempt to do Qt from C#. Have you looked at it (I have no idea how good it is or is not)? It should not remove licensing requirements.

Qt comes in many different licenses LGPL is probably the most popular and it's not much of a restriction if you ask me
I just want to replace QT (UI) part with C#
It's probably easier to just use C++/CLI. it links to the exact same libraries as C# but it remains C++ and allows you to mix managed and unmanaged code in the same project without going crazy
@prabhat As I said: you can use C++ with .Net/WPF. And you can't replace Qt with C# as C# is a programming language and Qt a framework. What you probably mean is that you want to replace Qt with WPF, but there is no need to switch to C# for that.
And as others said: most of Qt is LGPL not GPL. And LGPL is not so restrictive and usually OK for commercial/closed source software.
