Why would you use TransactionScope for Read-Only Database Calls in NET C#?

wish help you to fix your issue Firstly, in most relational databases, both read and write operations on database objects will always be executed inside a transaction. Even if you don't explicitly start a transaction, one will be started implicitly. This should at minimum answer the question of whether it makes sense to use transactions for read statements – in most cases you will end up with a transaction anyway. An example of a case where transactions are not implicitly created is a query like SELECT 2 * 3, that involves no database objects.
When we talk about transactions, we must also talk about isolation levels. Transactions do matter for read statements, the same way they do for all other kinds of database operations. The isolation level controls in which consistency state data is read, and if read locks are placed. In your example, the isolation level of the transaction is set to READ COMMITTED, which could have been done on purpose. Imagine your database has its default transaction level set to READ UNCOMMITTED - using the wrong isolation level here could have undesired side effects, depending on what you are trying to achieve with that query.

Will transactionscope work over multiple calls to different services?

will help you Yes, This will work. TransactionScope leverages the Distributed transaction coordinator so it's capable of hosting Transactions beyond database levels.
Recommended practice for DataContext lifecycle is to restrict it to a unit-of-work.

How can I force TransactionScope to use the same connection across Database calls?

I think the issue was by ths following , You already have the appropriate behavior as long as the DatabaseFactory class, whatever it is, behaves in a cooperating manner. If the someDao calls seem to act independently, it could mean they are actively creating an inner scope with TranscationScopeOption.Supress. Another issue could be if the CreateDatabase call internally caches some SqlConnection and does not relies on SqlClient connection pool, thus possibly by-passing the connection enrollment into the transaction.
As a side note, even when this works as desired, it will be mighty inefficient because you'll enroll two distinct connections into a distributed-transaction and this will slow processing a great deal. A good data access layer accepts the Sqlconnection to use as a parameter so it can share it between calls, thus keeping the transaction scope local on the server.

TransactionScope with Membership and Roles calls in same block (way to use only one connection?)

hope this fix your issue If you have SQL2008 or higher, it can handle a transaction across multiple connections, without escalating to MSDTC. The requirement is that you use exactly the same connection string for all connections.
If you're on a lower SQL server version I think that you loose. I investigated this a few months ago and found no way to handle it, so I ended up skipping the transactions and implementing my own error handling instead. The customer had SQL2005 and an upgrade was not possible.

Issue with TransactionScope and async calls with EF6

By : Guitar Guy

Any of those help This has nothing to do with async. You are writing on multiple connections and want that to be atomic. That requires distributed transactions. There is no way around that.
You also might run into distributed deadlocks this way that will only be resolved by timeouts.

TransactionScope transaction = new TransactionScope() VS TransactionScope s = context.Connection.BeginTransaction()

To fix this issue While Database. BeginTransaction() is used only for database related operations transaction, System. Transactions. ... TransactionScope for mixing db operations and C# code together in a transaction.
