It is common for you to want to check whether your application is the latest version of the application. It is possible to compare the version of your application against a version number that you have as a string
You can achieve this by doing something like;
Dim curVer As Version = My.Application.Info.Version
Dim availVer As Version = New Version("1.0.0.2")
If availVer > curVer Then
'The available version is newer
Else
'You either have the latest version or a future version.
End If
