Question

I am using TransactionScopes at a high level to wrap some high level code that makes a number of connections to the database.

One of the functions I call is a generic read that is used for read only functions where a read uncommitted isolation level is needed. But in some cases it is used as part of large update operation and a read committed would be more suitable.

At the highest level where I am calling my functions inside a transaction scope, should I be able to set the Isolation Level for the transaction?

Answer 1

You can set the isolation level on the TransactionScope itself. Is that what you mean?

using (var txn = new TransactionScope(     TransactionScopeOption.Required,      new TransactionOptions     {         IsolationLevel = IsolationLevel.ReadUncommitted     } )) {     // Your LINQ to SQL query goes here }
