Why OpenFileDialog for UWP C# App ReferenceNotFound?

uwp

(afree) #1

Hi,

I am trying to use OpenFileDialog on my UWP app for Windows 10 desktop but seems like the Reference couldn’t be found.

So is there any workaround to show OpenFileDialog in my UWP App?

Trying to use the OpenFileDialog is really a very common mistake that UWP newbies commit especially those coming from .NET framework.

I can’t deny that UWP is a .NET technology that targets .NET core itself. But it doesn’t target .Net Framework in its entirety. OpenFileDialog is part of System.Windows.Forms and it’s not part of .Net Core libraries. You should use FileOpenPicker instead for Windows Store Apps.
