من در مورد رشته اتصال Entity یه مشکل دارم
این رشته اتصال من در فایل App.config هست:
مخصوص اعضای ویژه 
<connectionStrings>
<add name="mssql"
connectionString="Data Source=DESKTOP-R4VE3E7\HOSSEINSQL; Initial Catalog=
Students_DB;Integrated Security=SSPI"
providerName="System.Data.EntityClient" />
</connectionStrings>ولی موقع استفاده این ارور رو میده:
