UpdateLib

UpdateLib is a .Net library that helps to provide an update mechanism for applications. It supports incremental updates and provides a simple MessageBox based UI and a overlay UI for Windows Forms. It uses a JSON based file format for update information.

The library is available on NuGet: https://www.nuget.org/packages/FloseCode.UpdateLib/

Example in VB.Net

Dim u As New FloseCode.UpdateLib.Update(programName, programExeFile, programVersion, programPath, tempPath, updateMirrorFile, New String() {"https://defaultUpdateServer"}, uid)

' Optional settings
u.StatisticsServer = "https://statisticsServer/sendStats"
u.ProductFlavor = "Portable"
u.CurrentReleaseChannel = "beta"

' Install update if one was downloaded previously
If u.InstallUpdate() Then Return

' Set version info in Windows registry, needs admin privileges
u.SetUninstallInfoInRegistry("{UUID}")

' Translate strings, uses TranslationLib
u.Translate(language, translatedProgramName)

' Search for update
u.SearchUpdateAsync()
