/// The algorithm for gathering versions from the registry is as follows:
/// 1) targetRuntimeVersion is the target framework version you are targeting
/// 2) versions is a string list from reading the registry, this list is in what ever order the registry returns
/// the keys to us in, this is usually alphabetical.
///
/// We will go through each version string and do the following:
/// 1) Check to see if the string is a version
/// If the string is not a version we will check to see if the string starts with the framework we are targeting,
/// if it does we will add it to a list which will be added at the end
/// of the versions list, if not it gets ignored. We do this to stay compatible to what we have been doing since whidbey.
///
/// If the string is a version
/// We check to see if the version is a valid target framework version. Meaning. It has a Maj.Minor version and may have
/// build, Build is less than or equal to 255 and there is no revision. The reason the build number needs to be less than 255 is because
/// 255 is the largest build number for a target framework version that visual studio 2010 supports. The build number is supposed to
/// represent a service pack on the 4.0 framework.
///
/// If the string is a valid target framework version we check to see we already have a dictionary entry and if not we
/// add one.
/// If the string is not a valid target framework then we will ignore the part of the version which makes it invalid
/// (either the build or the revision, or both) and see where that version would fit in the dictionary as a key and
/// then put the original version string into the list for that entry.
///
/// Since the dictionary is sorted in reverse order to generate the list to return we do the following:
/// Go through the list of dictionary entries
/// For each entry sort the list in reverse alphabetical order and add the entries in their internal list to the listToreturn.
///
/// This way we have a reverse sorted list of all of the version keys.
