protected abstract void Activate(Transaction transaction)

public abstract DbTransaction BeginTransaction(IsolationLevel il)

public virtual void ChangeDatabase(string value)

protected virtual void CleanupTransactionOnCompletion(Transaction transaction)

Cleanup connection's transaction-specific structures (currently used by Delegated transaction). This is a separate method because cleanup can be triggered in multiple ways for a delegated transaction.

protected abstract void Deactivate()

Deactivates the connection, cleaning up any state as necessary. A deactivated connection is one that is no longer in active use and does not have an owner. A deactivated connection may be open (connected to a server) and is checked into the connection pool (if pooling is enabled).

public virtual void Dispose()

public abstract void EnlistTransaction(Transaction transaction)

protected virtual bool ObtainAdditionalLocksForClose()

protected virtual void PrepareForCloseConnection()

protected virtual void ReleaseAdditionalLocksForClose(bool lockToken)

protected bool TryOpenConnectionInternal(DbConnection outerConnection, SqlConnectionFactory connectionFactory, TaskCompletionSource<DbConnectionInternal> retry, DbConnectionOptions userOptions)

protected void UnDoomThisConnection()

Reset connection doomed status so it can be re-connected and pooled.
