please tell me how resolve error possible.

we can't connect microsoft sql server directly uwp apps. system.data.sqlclient 4.1.0 package you've referenced .net core library. can use library in .net core apps (either asp.net core apps or console apps), however, can't use in uwp apps.

the common way access microsoft sql server database form uwp app host data service , app query data through rest api or wcf service. example, can check how access data sql server database in windows store app. video shows how create wcf service access data sql server database in windows store apps.
