One transaction with multiple dbcontexts

Question

I am using transactions in my unit tests to roll back changes. The unit test uses a dbcontext, and the service i\'m testing uses his own. Both of them are wrapped in one tra

Answer 1

For me, using 'Enlist=false' in the config file removed the DST error, but also invalidated the transaction, DB changes were persistent even if scope scope.Complete() was not reached:

using (var scope = new TransactionScope())  
using (var firstContext = new db1Context()) 
using (var secondContext = new db2Context())
{
// do smth with dbContexts
 scope.Complete();
}

I ended up using DbContextTransaction to solve this issue:

using (var firstContext = new db1Context())
using (var secondContext = new db2Context())
using (DbContextTransaction firstContextTransaction = db1Context.Database.BeginTransaction())
using (DbContextTransaction secondContextTransaction = db2Context.Database.BeginTransaction())
    {
    try
    {
    // do smth with dbContexts                    
    firstContextTransaction.Commit();
    secondContextTransaction.Commit();
    }
    catch (System.Exception)
    {
    firstContextTransaction?.Rollback();
    secondContextTransaction?.Rollback();
    throw;
    }
    }
