Hi Durgadevi,
WPF: (Windows Presentation Foundation)
Is a windows desktop framework within .Net Framework starting from v3.0. WPF uses XAML language for its UI drawing, and C# or VB.NET as a back-end programming language.
UWP: (Universal Windows Platform)
It's a new and evolved "universal" framework targeting Windows 10 (both Desktop & Phone). Universal windows apps are able to run on all devices running Windows 10 (PC, Mobile, Tablet, XBox...etc).
Therefore, their code will be different. You need to adjust the code for different platforms.
>>Equaliy Operator == is not working in Universal Windows
I suggest you can visit
the Developing Universal Windows apps forums for getting suitable help.
You can include all necessary code snippets for anyone else to be able to reproduce your issue from scratch along with a detailed description about the results including any exception messages.
Best Regards,
Yohann Lu
