ApplicationDeployment.CurrentDeployment Property

Returns the current ApplicationDeployment for this deployment.

Namespace:  System.Deployment.Application
Assembly:  System.Deployment (in System.Deployment.dll)
Public Shared ReadOnly Property CurrentDeployment As ApplicationDeployment

Property Value

Type: System.Deployment.Application.ApplicationDeployment
The current deployment.

You attempted to call this static property from a non-ClickOnce application.

You cannot create instances of ApplicationDeployment directly in your application; you must retrieve a valid instance through the CurrentDeployment property.

The CurrentDeployment static property is valid only from within an application that was deployed using ClickOnce. Attempts to call this property from non-ClickOnce applications will throw an exception. If you are developing an application that may or may not be deployed using ClickOnce, use the IsNetworkDeployed property to test whether the current program is a ClickOnce application.

The following code example retrieves CurrentDeployment and checks to determine whether the application has been updated in the past three days.

Private Function CheckForUpdateDue() As Boolean 
    Dim isUpdateDue As Boolean = False 

    If (ApplicationDeployment.IsNetworkDeployed) Then 
        Dim AD As ApplicationDeployment = ApplicationDeployment.CurrentDeployment
        Dim updateInterval As TimeSpan = DateTime.Now - AD.TimeOfLastUpdateCheck
        If (updateInterval.Days > 3) Then
            isUpdateDue = True 
        End If 
    End If

    CheckForUpdateDue = isUpdateDue
End Function
