UnitOfWork.EntityFrameworkCore 5.3.1

UnitOfWork.EntityFrameworkCore

A plugin for Microsoft.EntityFrameworkCore to support repository, unit of work patterns, and multiple database with distributed transaction supported.

Installation

Install-Package UnitOfWork.EntityFrameworkCore -Version 5.3.1

Usage

The following code demonstrates basic usage.

First of all, please register the dependencies into the MS Built-In container:

services.AddDbContext<ExampleDbContext>(options =>
            {
                options.UseSqlServer(Configuration.GetConnectionString(SystemConstants.MainConnectionString), sqlServerOptions =>
                {
                    sqlServerOptions.MigrationsAssembly((typeof(ExampleDbContext).Assembly).GetName().Name);
                });
            }).AddUnitOfWork<ExampleDbContext>();

After that, use the structure in your code like that:

private readonly IUnitOfWork _unitOfWork;
// Injection
 public ExampleController(IUnitOfWork<ExampleDbContext> unitOfWork )
        {
            _unitOfWork = unitOfWork;
        }

#returns GetAll

public async Task GetAll(){
  var books= _unitOfWork.GetRepository<Book>().GetAll();
}

returns Get ByFilter

public async Task GetAllByFilter(){
  var blogs = _unitOfWork.GetRepository<Book>().GetAllByFilter(
                predicate: x => x.Descriptions.Contains("Book Example"),
                orderBy: x => x.OrderByDescending(i => i.DateCreated),
                include: x => x.Include(i => i.Category));
}

returns GetPaging

public async Task GetAllByFilter(){
   var blogs = _unitOfWork.GetRepository<Blog>().GetPagedListAsync(
               predicate: x => x.Descriptions.Contains("Book Example"),
               orderBy: x => x.OrderByDescending(i => i.DateCreated),
               include: x => x.Include(i => i.Category),
               pageIndex:1,pageSize:20);
}

returns GetStagesPaging

public async Task GetStagesPaging(){
   var repository = _unitOfWork.GetRepository<Book>();
   var query = repository.Queryable()
                .Where(x => x.Descriptions.Contains("Book Example"));
   var books= _unitOfWork.GetRepository<Book>().GetStagesPagedListAsync(
               stages: query,
               selector:x=>x.Descriptions,
               pageIndex: 1, pageSize: 20);
}

returns GetBookById

public async Task voidGetBookById(int id){
  var book= await _unitOfWork.GetRepository<Book>().FindAsync(id);
}

returns AddBook

public async Task AddBook(Book book){
    await _unitOfWork.GetRepository<Book>().InsertAsync(book);
    await _unitOfWork.SaveChangesAsync();
}

returns UpdateBook

public async Task UpdateBook(Book book){
    _unitOfWork.GetRepository<Book>().Update(book);
    await _unitOfWork.SaveChangesAsync();
}

returns DeleteBook

public async Task DeleteBook(int id){
    _unitOfWork.GetRepository<Book>().Delete(id);
    await _unitOfWork.SaveChangesAsync();
}

returns GetBookCount

public async Task GetBookCount(){
   var count= _unitOfWork.GetRepository<Book>().CountAsync(id);
}
