2.The Service Side Configuration
1, Create a new IIS site.
2, Disable * dll handles mapping to allow dll file to download.
3, On this site to create a desktop program subdirectory, such as /demo/.

i) Extension for Updater
In the SharpUpdater source code，we did not implement this interface, see CnSharp.Windows.Updater/Common.cs/Ln.14。Therefore, by default only show the update log of the current version; assume that the user upgrade from V1.0 to
V1.4, you can only see V1.4 update log, can not see V1.1 ~ V1.3 . Developers can implement it own.
2,SharpUpdater source code based on MIT lisence，you can modify it freely.
ii) Extension for SharpPack
1,Base Class: CnSharp.Windows.Updater.SharpPack.Connect
This class provides a group of protected virtual methods to override.You can custom your own UI or actions.
This interface helps you check out the AssemblyInfo.cs to modify version number.Default implement is for TFS,you can implement it for other source control tools,such as SVN.
