LINQ TO SQL TRANSACTIONSCOPE ERROR - linq-to-sql

Question

I am getting an error on TransactionScope() and datacontext as below.
The type or namespace name 'TransactioScope' could not be found (are you missing a using directive or an assembly reference?)
The type or namespace name 'HRPaidTimeOffDataContext' could not be found (are you missing a using directive or an assembly reference?)
What must I do to fix this issue in the code below.
using ( TransactioScope ts = new TransactionScope())
{
// Create the data context
using (HRPaidTimeOffDataContext db = new HRPaidTimeOffDataContext())
{
//Now save the record
if (this.Save(db, ref validationErrors, userAccountId))
{
// Commit transaction if update was successful
ts.Complete();
return true;
}
else
{
return false;
}
}
}

Answer 1

are you missing a using directive or an assembly reference?
Yes, you are missing that. Two actually...
The first: TransactionScope.
In the documentation (http://msdn.microsoft.com/en-us/library/system.transactions.transactionscope.aspx) you wil find:
Namespace: System.Transactions
Assembly: System.Transactions (in
System.Transactions.dll)
So you need to include this line in the top of your code:
using System.Transactions;
The other one is one of your own
HRPaidTimeOffDataContext
So I cannot tell you what to type, but I guess you will manage by now.
