 virtual IAsyncOperationWithProgress<DeploymentResult ^, DeploymentProgress> ^ RemovePackageAsync(Platform::String ^ packageFullName) = RemovePackageAsync;

/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperationWithProgress<DeploymentResult, DeploymentProgress> RemovePackageAsync(winrt::hstring const& packageFullName);

[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperationWithProgress<DeploymentResult,DeploymentProgress> RemovePackageAsync(string packageFullName);

function removePackageAsync(packageFullName)

Public Function RemovePackageAsync (packageFullName As String) As IAsyncOperationWithProgress(Of DeploymentResult, DeploymentProgress)

Parameters

packageFullName: String
Platform::String

winrt::hstring

A string representation of the package identity to identify the package to be removed.

Returns

IAsyncOperationWithProgress<DeploymentResult,DeploymentProgress>

The status of the deployment request. The DeploymentResult contains the final returned value of the deployment operation, once it is completed. The DeploymentProgress can be used to obtain the percentage of completion over the entire course of the deployment operation.

Attributes: RemoteAsyncAttribute

Examples

Call the RemovePackageAsync(String) method to uninstall the app package. Notice that the package full name in packageFullName comes from a command-line argument.

RemovePackageAsync(String) returns an object that can be used to manage the asynchronous operation. Use the Completed property to set the delegate. Check the Status property to determine the status of the deployment operation. If the status is Error, the example calls the GetResults method to get additional error information.

using Windows.Foundation;
using Windows.Management.Deployment;

[STAThread]
public static int Main(string[] args)
{
    string inputPackageFullName = args[0];
    int returnValue = 0;

    PackageManager packageManager = new Windows.Management.Deployment.PackageManager();

    IAsyncOperationWithProgress<DeploymentResult, DeploymentProgress> deploymentOperation = 
        packageManager.RemovePackageAsync(inputPackageFullName);
    // This event is signaled when the operation completes
    ManualResetEvent opCompletedEvent = new ManualResetEvent(false); 

    // Define the delegate using a statement lambda
    deploymentOperation.Completed = (depProgress, status) => { opCompletedEvent.Set(); };

    // Wait until the operation completes
    opCompletedEvent.WaitOne();

    // Check the status of the operation
    if (deploymentOperation.Status == AsyncStatus.Error)
    {
        DeploymentResult deploymentResult = deploymentOperation.GetResults();
        Console.WriteLine("Error code: {0}", deploymentOperation.ErrorCode);
        Console.WriteLine("Error text: {0}", deploymentResult.ErrorText);
        returnValue = 1;
    }
    else if (deploymentOperation.Status == AsyncStatus.Canceled)
    {
        Console.WriteLine("Removal canceled");
    }
    else if (deploymentOperation.Status == AsyncStatus.Completed)
    {
        Console.WriteLine("Removal succeeded");
    }
    else
    {
        returnValue = 1;
        Console.WriteLine("Removal status unknown");
    }

Remarks

For a call to this method to be successful, the caller needs to fulfil one of these conditions:

The caller is running in an AppContainer (Low IL) and it has the packageManagement restricted capability.
The caller is running with Medium IL, or higher.
The caller’s publisher matches the publisher of the package (or volume) being removed.

For descriptions of the terms above, and links to more info, see Packaging, deployment, and process.

This request can't be canceled. The package full name is an alternate form of the package identity that is shorter and is suitable for naming objects such as files and directories. A package identity is represented by the Identity element of the package manifest. When a package is removed it is removed for the current user, which means that the package payload continues to exist if other users have installed the package, but it will not be accessible to the current user. If no other users have the specified package installed, its payload will be removed from the %ProgramFiles%\WindowsApps directory. Any app associated with the package that is being removed will be shutdown automatically as part of the package removal.
