Hi,

see the below link it might be help you to solve your problem. The error occurs due to fetch so much data at a time. Better to fetch records in some interval. you can use paging. Might be it will solve your problem.

XML

Basically such scenario generate due to high execution sql query cost.
You can set appropriate timeout in connection string as below :

<appSettings>
        <add key="Connstr" value="Server=192.168.1.6\SQLExpress;database=Mydatabase;timeout=100000;uid=usename;pwd=password;"/>
    </appSettings>

and use below  preventive/precautionary steps for minize table scan :
1)Define appropriate index on database table.
2)Check query execution cose using explain plan.
3)Try to avoid such full table scan query.
