How does Entity Framework handle transactions?

Question

Entity Framework (EF) handles transactions to ensure that a group of database operations either all succeed or all fail — maintaining
data integrity.
EF manages transactions automatically for simple scenarios, and also allows
manual transaction handling for more complex use cases.
1. Automatic Transaction Handling
When you call SaveChanges(), EF wraps the changes in a transaction:
using (var context = new MyDbContext())
{
    context.Products.Add(new Product { Name = "Phone" });
    context.SaveChanges(); // Wrapped in a transaction automatically
}
If something fails during SaveChanges(), EF will roll back the transaction.
2. Explicit Transactions with DbContextTransaction
For multiple operations where you want atomicity, you can use:
using (var context = new MyDbContext())
{
    using (var dbContextTransaction = context.Database.BeginTransaction())
    {
        try
        {
            context.Products.Add(new Product { Name = "Tablet" });
            context.SaveChanges();
            context.Customers.Add(new Customer { Name = "Anna" });
            context.SaveChanges();
            dbContextTransaction.Commit();
        }
        catch
        {
            dbContextTransaction.Rollback(); // Rollback all changes
        }
    }
}
3. Using TransactionScope (System.Transactions)
Useful when:
You want to include multiple DbContextsOr combine EF with ADO.NET/manual DB calls
using (var scope = new TransactionScope())
{
    using (var context = new MyDbContext())
    {
        context.Orders.Add(new Order { Total = 500 });
        context.SaveChanges();
    }
    using (var anotherContext = new AnotherDbContext())
    {
        anotherContext.Logs.Add(new Log { Message = "Order placed" });
        anotherContext.SaveChanges();
    }
    scope.Complete(); // Commits both contexts
}
TransactionScope may escalate to a distributed transaction depending on database configuration (e.g., MSDTC required).
4. Asynchronous Transaction Handling (EF6+)
using (var context = new MyDbContext())
{
    using (var transaction = context.Database.BeginTransaction())
    {
        try
        {
            context.Users.Add(new User { Name = "Alice" });
            await context.SaveChangesAsync();
            context.Logs.Add(new Log { Message = "User added" });
            await context.SaveChangesAsync();
            transaction.Commit();
        }
        catch
        {
            transaction.Rollback();
        }
    }
}
Summary
Use Case
Method
Single SaveChanges() call
Auto transaction (default behavior)
Multiple DB operations
BeginTransaction(), Commit(), Rollback()
Multiple DbContext or external ops
TransactionScope (System.Transactions)
Async-safe transaction
Use await + BeginTransaction()

Use Case	Method
Single `SaveChanges()` call	Auto transaction (default behavior)
Multiple DB operations	`BeginTransaction()`, `Commit()`, `Rollback()`
Multiple `DbContext` or external ops	`TransactionScope` (System.Transactions)
Async-safe transaction	Use `await` + `BeginTransaction()`
