Hi Emil, 
Thanks for contacting Syncfusion Support. 
We have checked your query. This is a known framework issue in UWP platform. Custom controls will not render properly in the Release mode in UWP platform. We have already reported this issue in Bugzilla and you can refer the below Bugzilla report for more details about this issue. 
However, you can overcome this issue in sample level by initializing the SfDataGrid assemblies in App.xaml.cs in UWP project as in below code snippet. 
// In App.xaml.cs 
protected override void OnLaunched(LaunchActivatedEventArgs e) 
    // Do not repeat app initialization when the Window already has content, 
    // just ensure that the window is active 
    if (rootFrame == null) 
        // Create a Frame to act as the navigation context and navigate to the first page 
        rootFrame = new Frame(); 
        rootFrame.NavigationFailed += OnNavigationFailed; 
        List<Assembly> assembliesToInclude = new List<Assembly>(); 
        //Now, add in all the assemblies your app uses 
        //Also do this for all your other 3rd party libraries 
        Xamarin.Forms.Forms.Init(e, assembliesToInclude); 
        if (e.PreviousExecutionState == ApplicationExecutionState.Terminated) 
            //TODO: Load state from previously suspended application 
        // Place the frame in the current Window 
        Window.Current.Content = rootFrame; 
We have attached a simple sample with Release mode for your reference and you can download the same from the below location. 
Please refer the below UG link for more details,

I have a question - what do you mean by the comment line in your sample stating that we should add all other 3rd party assemblies ? I have references to SfNavigationDrawer and various AWS dll's in the UWP project. Do I need to add any in to your workaround code ?

My problem is as follows - I have implemented pull to refresh in the PCL and it works very well on iOS but does not work in UWP. I am running the UWP in Debug mode and not in the Release mode.

Thank you.

Hi Halil,

Thanks for the update.

Regarding your first query "what do you mean by the comment line in your sample ? Do I need to add any in to your workaround code " , yes you have to add the renderers to the AssembliesToInclude list for all the controls that you are using , so that the control’s renderers are initialized and loaded properly without any crashes in release mode for UWP platform.

Regarding your second query of pull to refresh not working in SfDataGrid for UWP, we have checked the same from our side and is working properly for us. Please refer the video samples of the test from the below link.

Is there some solution for a UWP C# desktop app? Not Xamarin

Hi Lakshmi,

I have a similar problem with sfchart control, in which, when I start my desktop uwp application in release mode, the chart is not displayed. In debug everything works fine.

I opened a request at  UWP - Chart not rendering in Release mode | UWP Forums | Syncfusion
