DistributedTransactionPermission Class

The permission that is demanded by System.Transactions when management of a transaction is escalated to MSDTC. This class cannot be inherited.

Namespace: System.Transactions
Assembly: System.Transactions (in system.transactions.dll)

[SerializableAttribute] 
public ref class DistributedTransactionPermission sealed : public CodeAccessPermission, IUnrestrictedPermission
/** @attribute SerializableAttribute() */ 
public final class DistributedTransactionPermission extends CodeAccessPermission implements IUnrestrictedPermission
SerializableAttribute 
public final class DistributedTransactionPermission extends CodeAccessPermission implements IUnrestrictedPermission
Not applicable.

A local transaction only consumes resources from a single durable source or mutilple volatitle sources. A distributed transaction, on the other hand, has to interact with multiple durable resources, potentially across the network. When management of a transaction is escalated to MSDTC, the code that initiated the escalation is verified to have this permission. For more information on security levels, see Security in System.Transactions. For more information on transaction management escalation, see Promotion of Transactions. The security demand affects the code that initiated the escalation, not necessarily the code that originally created the local transaction.
