How to know the download link of a windows phone 8 application - windows-phone-7

Question

I'm developing windows phone 8 application. In which I have to share the application's download link on Facebook and Twitter.
Before publishing the application on to the windows phone store, How could I know the download link of the application.
Because we have to implement the share functionality before publishing the application.
I'm looking forward for your responses.
Thanks & Regards,
Suresh

Basically your application download link format is as follow :
http://windowsphone.com/s?appid=<ApplicationId>
with <ApplicationId> is value of ProductID attribute of App element in WMAppManifest.xml file. That ProductID in WMAppManifest.xml will be overridden when you submit the Apps to Marketplace, so avoid hardcoding it. This post demonstrates how to get <ApplicationId> from manifest file as well as how to share it using Microsoft.Phone.Tasks.ShareLinkTask.
UPDATE :
To summarize, create a helper class to read ApplicationID from WMAppManifest.xml file :
public class DeepLinkHelper
{
private const string AppManifestName = "WMAppManifest.xml";
private const string AppNodeName = "App";
private const string AppProductIDAttributeName = "ProductID";
public static string BuildApplicationDeepLink()
{
var applicationId = Guid.Parse(GetManifestAttributeValue(AppProductIDAttributeName));
return BuildApplicationDeepLink(applicationId.ToString());
}
public static string BuildApplicationDeepLink(string applicationId)
{
return #"http://windowsphone.com/s?appid=" + applicationId;
}
public static string GetManifestAttributeValue(string attributeName)
{
var xmlReaderSettings = new XmlReaderSettings
{
XmlResolver = new XmlXapResolver()
};
using (var xmlReader = XmlReader.Create(AppManifestName, xmlReaderSettings))
{
xmlReader.ReadToDescendant(AppNodeName);
if (!xmlReader.IsStartElement())
{
throw new FormatException(AppManifestName + " is missing " + AppNodeName);
}
return xmlReader.GetAttribute(attributeName);
}
}
}
Then you can get/share download link this way :
new Microsoft.Phone.Tasks.ShareLinkTask()
{
Title = "My Application Deep Link",
Message = "My Application Deep Link",
LinkUri = new Uri(DeepLinkHelper.BuildApplicationDeepLink())
}.Show();
