OUTDATED--

Repository pattern implementation for C#.

A universal repository for working with multiple databases:

• InMemory
• Azure Tables
• CosmosDB
• LiteDB
• SQLite
• MSSQL
• PostgreSQL

General concept

We don't think you can hide the real database completely behind abstractions, so I recommend using your interfaces that will lend IReposity of the right type. And do the same with the direct implementation.

// declare the model as a descendant of the base type.
public class SomeModel : IItem<T>
{

}

// then create an interface
public interface ISomeRepository : IRepository<TId, TItem> where TItem : IItem<TId>
{
}

// create a class inherited from a repository of the desired type
public class SomeRepository : BaseRepository<TId, TItem> where TItem : class, IItem<TId>, new()
{
}

And then add your interface and dependency configuration class.

services
        .AddTransient<ISomeRepository, SomeRepository>()

This is to define the id type, and the object itself.

Azure Table

// declare the model as a descendant of the base type.
public class SomeModel : AzureTableItem
{

}


// then create an interface
public interface ISomeRepository : IAzureTableRepository<SomeModel>
{
}


// create a class inherited from a repository of the desired type
public class SomeRepository : AzureTableRepository<SomeModel>, ISomeRepository
{
    public SomeRepository(ILogger<SomeRepository> logger, IConfiguration config) : base(logger, 
        new AzureTableRepositoryOptions
        {
            ConnectionString = "connectionString"
        })
    {
    }
}

CosmosDB

// declare the model as a descendant of the base type.
public class SomeModel : CosmosDbItem
{

}


// then create an interface
public interface ISomeRepository : ICosmosDbRepository<SomeModel>
{
}


// create a class inherited from a repository of the desired type
public class SomeRepository : CosmosDbRepository<SomeModel>, ISomeRepository
{
    public SomeRepository(ILogger<SomeRepository> logger, IConfiguration config) : base(logger, 
        new CosmosDbRepositoryOptions
        {
            ConnectionString = "connectionString"
        })
    {
    }
}

LiteDB

// declare the model as a descendant of the base type.
public class SomeModel : LiteDbItem<string>
{

}


// then create an interface
public interface ISomeRepository : ILiteDbRepository<string, SomeModel>
{
}


// create a class inherited from a repository of the desired type
public class SomeRepository : LiteDbRepository<SomeModel>, ISomeRepository
{
    public SomeRepository(ILogger<SomeRepository> logger, IConfiguration config) : base(logger, 
        new LiteDbRepositoryOptions
        {
            ConnectionString = "connectionString"
        })
    {
    }
}

MongoDB

// declare the model as a descendant of the base type.
public class SomeModel : MongoDbItem<string>
{

}


// then create an interface
public interface ISomeRepository : IMongoDbRepository<SomeModel>
{
}


// create a class inherited from a repository of the desired type
public class SomeRepository : MongoDbRepository<SomeModel>, ISomeRepository
{
    public SomeRepository(ILogger<SomeRepository> logger, IConfiguration config) : base(logger, 
        new LiteDbRepositoryOptions
        {
            ConnectionString = "connectionString"
        })
    {
    }
}

SQLite

// declare the model as a descendant of the base type.
public class SomeModel : SQLiteItem
{

}


// then create an interface
public interface ISomeRepository : ISQLiteRepository<string, SomeModel>
{
}


// create a class inherited from a repository of the desired type
public class SomeRepository : SQLiteRepository<SomeModel>, ISomeRepository
{
    public SomeRepository(ILogger<SomeRepository> logger, IConfiguration config) : base(logger, 
        new SQLiteRepositoryOptions
        {
            ConnectionString = "connectionString"
        })
    {
    }
}
