Initially we didn’t use any source control software. Now we are using TFS 2010 for version control. Currently we are facing issue related to how to handle changes with production code and code that is under development.
Assuming we have published a version 1.0 to the web using visual studio 2010 publish with source code x. Now we continue to work on the source code to implement more features. Noow the source code has changed to x.something.
During that time we receive bugs reported by users. Now how to handle such situations since bugs has to be fixed in source code version x. And we don’t want to use x.something version since it has few unfinished features which we don’t want to publish on production.
At this time what is the recommended practice.
Are there two repositories for different versions of source code? If yes then how to fix errors when then come –first update current version or the published code, since we don’t want those errors to exist in current development version.
look into Branching – you can find a good guid here:
TFS Branching Guidance
I think you need/want something like the Branch per Release of Code-Promotion Branches described [here]:
or 
2
I like those too, but they are more comples (too complex?):
