FrameworkRepository 1.0.7

Framework Repository

A class library that implements the generic repository pattern using Entity Framework Core as base.

Usage

First register repositories interfaces and classes in dependency injection using the automatic registration method.

    builder.Services.AddRepositories();

Note: All repositories are registered with a scoped lifetime, to change that you can use the optional parameter and assign a lifetime from these options (Transient, Scoped And Singleton).

    builder.Services.AddRepositories(ServiceLifetime.Transient);

After that you can use the repository interfaces through constructor injection.

    public Test(IReadOnlyRepository<User, DefaultDbContext> readonOnlyRepository,
                IRepository<User, DefaultDbContext> repository,
                ITransactionRepository<User, DefaultDbContext> transactionRepository,
                IRawRepository<DefaultDbContext> rawRepository)
    {
    }

The User type is an Entity Framework Core POCO class which represents a table, while DefaultDbContext is the DbContext which will be requested by the repository when created by the IOC.

Each repository interface have it's own usage.<br/><br/>

The IReadOnlyRepository<> can only retrieve data.<br/><br/>

The IRepository<> can retrieve data and add/update/delete entities.<br/><br/>

The ITransactionRepository<> can do the same functions as IRepository<> but with two extra methods SaveChanges() which commits data and CreateTransaction() which creates a transaction (if non exists) and returns it.<br/><br/>

The IRawRepository<> has different methods that receives a string command/procedure and a list of parameters to execute.
