Important

Returns the current ApplicationDeployment for this deployment.
public:
static property System::Deployment::Application::ApplicationDeployment ^ CurrentDeployment { System::Deployment::Application::ApplicationDeployment ^ get(); };public static System.Deployment.Application.ApplicationDeployment CurrentDeployment { get; }static member CurrentDeployment : System.Deployment.Application.ApplicationDeploymentPublic Shared ReadOnly Property CurrentDeployment As ApplicationDeploymentThe current deployment.
You attempted to call this static property from a non-ClickOnce application.
The following code example retrieves CurrentDeployment and checks to determine whether the application has been updated in the past three days.
public:
bool CheckForUpdateDue()
{
bool isUpdateDue = false;
if (ApplicationDeployment::IsNetworkDeployed)
{
ApplicationDeployment^ dueAppDeployment =
ApplicationDeployment::CurrentDeployment;
TimeSpan^ updateInterval =
DateTime::Now - dueAppDeployment->TimeOfLastUpdateCheck;
if (updateInterval->Days >= 3)
{
isUpdateDue = true;
}
}
return (isUpdateDue);
}
private Boolean CheckForUpdateDue()
{
Boolean isUpdateDue = false;
if (ApplicationDeployment.IsNetworkDeployed)
{
ApplicationDeployment ad = ApplicationDeployment.CurrentDeployment;
TimeSpan updateInterval = DateTime.Now - ad.TimeOfLastUpdateCheck;
if (updateInterval.Days > 3)
{
isUpdateDue = true;
}
}
return (isUpdateDue);
}
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
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.
