Caution note Caution

Please refer to the SOLO Server manual for details on configuring product updates.

This example shows how to make a typical UpdateCheck call:
public bool CheckForUpdates(int licenseID)
    UpdateCheck updateChecker = new UpdateCheck();
    updateChecker.LicenseID = licenseID; //Optional if the ProductID property is set.
    updateChecker.ProductID = 12345; //Optional if the LicenseID property is set. TODO: Remove or update this line to your ProductID assigned in SOLO Server!  
    updateChecker.CurrentVersion = ""; //TODO: Update this line to use your application's version number!
    updateChecker.ProductUpdateName = "XYZ Product"; //TODO: Update this line of code to use the Product Update Name configured in SOLO Server!

    if (!updateChecker.CallWebService())
        //TODO: check the LastError property and add error reporting here!
        return false;

    if (updateChecker.ActionToTake != UpdateCheck.UpdateAction.None)
        //TODO: Add your update logic here!

    return true;
