Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

Appreciate if anyone could help me to resolve this issue.

I am using DataServiceContext to get data from SQL DB using WCF service and Connection string and StackTrace is as under as under:

<add name="Entities" connectionString="metadata=res://*/MYDB.csdl|res://*/MYDB.ssdl|res://*/MYDB.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=MyDataSource;initial catalog=MyDB;user id=sa;password=Pass@123;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
