Hi Chandra sekhar,
Thanks for contacting Syncfusion Support.
We can able to reduce the app bundle size by referring the needed controls DLL alone, instead of referring the SDK. We can get SfChart’s DLL from the below directory.
Directory: [Installed location] \Program Files (x86)\Syncfusion\Essential Studio\[build version]\Assemblies for Universal Windows\10.0 \Syncfusion.SfChart.UWP.dll
