                {
                    ShowPlacesList = true,
                    Multiselect = false,
                    InitialDirectory = "",
                    IsFolderPicker = false,
                    AddToMostRecentlyUsedList = false,
                    EnsurePathExists = true,
                    EnsureFileExists = true,
                    EnsureValidNames = true,
                    Title = "Open Model"
                    //DefaultDirectory = ""
                    //EnsureReadOnly = false
                    //AllowNonFileSystemItems = false
            };

I wonder are there any general platform functions which has scope all Windows versions

Hi,
The defined scope is too broad. There is not possible to support all Windows versions (16,32,64-bit, Mobile, ARM). You'll need to be more specific.

If you are using the built-in OpenFileDialog, it will run on any computer running Windows. Have a look at https://www.emoreau.com/Entries/Articles/2003/06/Common-Dialogs.aspx

Hi Éric,

Is there any support for WPF ?

Hi,
The WinForms OpenFileDialog is a wrapper over native Windows API calls. There is a such a wrapper in WPF, too, but the result is the same.

Hi Hakan,

OpenFileDialog will work across Windows versions (all currently supported versions of Desktop/Server editions) but it will not work on cross-platforms i.e. Linux, Mac etc.

Regards,
Chinmay.

Hi,
There is no direct support for UI development, cross-platform, in .NET. There are some alternative projects, but nothing native, to call it like this. However, you can have a look at Mono, instead. https://www.mono-project.com/docs/gui/
This project is under Microsoft's .NET umbrella, but there is some long road ahead till it will get fully integrated with the framework.

which platforms are you targeting? Usually, your UI will be recreated for various platforms because the look is totally different. You can reuse the same business layer but with different UI.

Eduard, isn't Mono almost dead now that it has been converted to Xamarin (which is part of Visual Studio)? https://dotnet.microsoft.com/apps/xamarin

Hi,

Mono is not really dead as long as Xamarin was targeted for mobile platforms. In a couple of years probably it is going to be discontinued when .Net 5.0 will hit the market (the latest greatest that it's aiming to unify all the .Net versions and incarnations). In the end, probably they will favor WPF over other technologies, but we'll see.
