public bool IsPersistent {get; set;}

'Declaration
 
Public Property IsPersistent As Boolean

Property Value

When the IsPersistent property is set to true, the message is queued persistently in the database and cannot be lost upon database failures or shutdowns. The database performs faster if the message is stored in an in-memory queue rather than a database queue.

The default value is false.
