Telerik UI for Windows Phone has two types of official releases – major and minor releases.
Examples of major releases are Q1 2011, Q3 2011 and examples of minor releases are Q3 2011 SP1,
Q3 2011 SP2 and Q1 2012 SP1. Both major and minor releases are distributed as msi installation
package which follows certain upgrade logic explained below.
First, major releases can be installed in parallel on the same machine. This means that when you install
new major release it doesn’t uninstall your existing major releases. An example is that you can have
Q2 2011, Q3 2011 and Q1 2012 installed at the same time.
Minor releases on the other hand can’t be installed in parallel when they are from the same major release.
This means that when you install a newer minor release it will automatically uninstall the previous version
minor release which is from the same major release. An example is that if there are two minor releases for
the same major release e.g. Q1 2012 SP1 and Q1 2012 SP2 for the Q1 2012 release then you can have only one
of the specified versions.
Here are some sample scenarios:
I. Parallel major releases
II. Minor releases from the same major release
III. Minor releases from different major releases
The Visual Studio Extensions are part of the Telerik UI for Windows Phone. Since they integrate into
the Visual Studio IDE they don’t support parallel versions. When newer version is installed regardless
of its type (major/minor) the Visual Studio Extensions get updated to the newer version.
