Source Control is a must while developing big projects with big teams ideally you should use a source control if you are not working alone on the project. With Visual Studio there are a no of options available but today in this article i will discuss about Collabnet Subversion in combination with ANKH Subversion and Tortoise SVN. Although other options available are also good and have their own unique features but if you want a source control combination for free then this is the combination which is best suited to you. Among other options Source Gear Vault and Source Fortress which are also good source control tools. Other option available is VisualSVN which is a Visual Studio Plugin, which integrates within the Visual Studio the power of Subversion and Tortoise but its not free so the best combination available is Collabnet Subversion+Tortoise SVN + AnkhSubversion.
