so after creating a branch developer works under his/her branch (checksout, checks-in the code) and when developers are done with there work they merge back their own branch into Main-Branch and CI Triggers everytime they check in.

Now as i am keeping solution file under development folder solution file does not goes to a developer branch. So How developers will be able to add there projects in the solution file.

(wht i think, developers will work in there own solution files and run the code and compile it. they wont do anything in solution file which is in repository. and they are only going to check-in the projects in there own branches when they r done and merge back to the Main-Branch. and later build engg will add those projects in the solution file which is in Development Folder)

But only problem i am facing in this method is, As the "Main-Branch" is a part of Continuos Integration a moment any developers merges back his/her Project from there branch to this branch and checks in, its going to trigger the CI. Now ofcourse the project files will be a part of the Branch as a changeset, But its not going to be part of Solution. So its not going to be actually build, even though it will be pulled down to a build machine, but just like a copy not as a part of solution.

So then Later on again Someone has to add the project in the solution and check in , which will trigger the CI again and this time it will be part of Solution.?

Any Comments, Better way? How this can be achieved.....
