Sharing Common Code
Several Options
• Share source code as projects
• Manually copy assemblies
• Branching

3. Branching in TFS 2010: Part V
Sharing Source Code
• Multiple versions are too hard to
manage
• Allows access to source to all
developers
• Increases build times of all projects

4. Branching in TFS 2010: Part V
Manually Copying Assemblies
• Multiple versions easier to manage
• Restricts access to source code
• Build times are not affected
• No tracking or auditing

5. Branching in TFS 2010: Part V
Branching Assemblies
• All advantages of manually
copying
• TFS provides tracking and auditing
• TFS provides ability to rollback
• Slightly more complicated (if new
to branching)

6. Branching in TFS 2010: Part V
Setting it Up:
• Need a “Deploy” folder in common
library project
• Built assembly goes in here for
each release
• This can be automated

Folder Structure of Shared Library

8. Branching in TFS 2010: Part V
Automating the “Deploy” folder:
• Post-build event to copy output
assembly to “Deploy” folder
• Existing assembly might be read-
only
• Pre-build event to check out
assembly

Post-Build Event

Set Up of Referencing Application
Needs a “Lib” folder. Two Options:
• One for entire solution
• One for each project

12. Branching in TFS 2010: Part V
Per Solution
• Easier
• No duplicates per project
• Can only have one version per
solution

13. Branching in TFS 2010: Part V
Per Project
• Duplicates per project
• Slightly more complicated
• Can have different versions
mixed in solution

14. Branching in TFS 2010: Part V
Sharing the Assembly
• Pick a specific release branch
• Open the “Deploy” folder
• Branch the actual .dll file to
another project’s “Lib” folder
