Answer 1

Same approach as the answer, just demonstrating using strongly typed result set.

void Main()
{
    int[] operationIds = { 1000, 1001 };
    var result = ObjectContext.ExecuteStoreQuery(
                        $@"SELECT OperationId, Name, OfficialId, IsPatientEncrypted FROM Patient WHERE OperationId IN ({string.Join(",", operationIds)})");
                        result.Dump();
}

Dump method is a method in Linqpad. Screenshot of working sample in Linqpad 5:

As the accepted answer said:

• Build a query string against the store where you build up the IN clause using for example string.Join to build up the comma separated array of string values
  • When using ExecuteStoreQuery you can in case you use a SELECT project the data into a strongly typed entity of your choice - as long as its properties and respective property types match up with database contents such that Entity Framework can successfully materialize the contents into the POCO object you use as a generic argument.
