![]() ![]() But it’s actually pretty common to implement a Unit of Work pattern that way. There is no such object in my implementation. In Entity Framework the DBContext both contains the generic repositories and is the unit of work. If you’re familiar with the Entity Framework DbContext unit of work, you may have noticed a difference as soon as you read the usage. What if I don’t want to use an ambient context? Can I link the unit of work and the repositories in some other way? The full version is available on github here: ![]() _unitOfWork = new UnitOfWork(_connection) "Cannot begin a transaction before the unit of work from the last one is disposed") "There is not current unit of work from which to get a connection. Public UnitOfWorkContext(SQLiteConnection connection) Private bool IsUnitOfWorkOpen => !(_unitOfWork = null || _unitOfWork.IsDisposed) Private readonly SQLiteConnection _connection Public class UnitOfWorkContext : IUnitOfWorkContext, IConnectionContext Calls to the repositories are done within the lifetime of a UnitOfWork, provided by a IUnitOfWorkContext. I’ll be using C# and Dapper on top of a SQLite in-memory database: I’ll be using a style of Unit of Work that allows for separately injectable repositories and avoids god objects (explained in detail at the bottom). In SQL the underlying mechanism for achieving this is to use a transaction, but the concept is more general and not tied specifically to SQL. They all need to succeed or fail together.Ī Unit of Work is a bucket that we put all these separate operations into so they can be run together. A partial update, when some calls fail and some succeed is not okay. Multiple methods on multiple different repositories must be called. When using a repository pattern, it’s a common to run into the following situation: Running one of your ‘business transactions’ (a login request, a customer order etc) requires multiple entities to be updated. ![]()
