C# Class GitSharp.Core.Repository

Represents a Git repository. A repository holds all objects and refs used for managing source code (could by any type of file, but source code is what SCM's are typically used for). In Git terms all data is stored in GIT_DIR, typically a directory called .git. A work tree is maintained unless the repository is a bare repository. Typically the .git directory is located at the root of the work dir.
  • GIT_DIR
    • objects/ - objects
    • refs/ - tags and heads
    • config - configuration
    • info/ - more configurations
This class is thread-safe. This implementation only handles a subtly undocumented subset of git features.
