What this means? Dexterity supported only Microsoft Visual SourceSafe (fondly called VSS), which has been used under discontinued support from Microsoft. Those who wants to streamline Dexterity Development on their organizations, found it very difficult to use something which is not supported by Microsoft but Dexterity.
Microsoft introduced Team Foundation Server (TFS) which is advanced and very easy to use and maintain. With Dexterity 2010 R2 release, the biggest gap in Dexterity Development history is now filled.
