Implement EF Repository in SocNet.Core project

[IgorGribowsky]

1. Add new project.
2. Add Domain model.
3. Add ApplicationContext.
4. Add Repository with generic methods

My solution in repository:

  public class Repository : IRepository
  {
      private ApplicationContext _context;

      public Repository(ApplicationContext context)
      {
          _context = context;
      }

      public IQueryable<TEntity> Query<TEntity>() where TEntity : class
      {
          var _dbSet = _context.Set<TEntity>();

          return _dbSet.AsNoTracking();
      }

      public TEntity Get<TEntity>(int id) where TEntity : class
      {
          var _dbSet = _context.Set<TEntity>();

          return _dbSet.Find(id);
      }

      public void Create<TEntity>(TEntity item) where TEntity : class
      {
          var _dbSet = _context.Set<TEntity>();

          _dbSet.Add(item);
          _context.SaveChanges();
      }

      public void Update<TEntity>(TEntity item) where TEntity : class
      {
          var _dbSet = _context.Set<TEntity>();
          _dbSet.Attach(item);
          _context.Entry(item).State = EntityState.Modified;
          _context.SaveChanges();
      }

      public void Remove<TEntity>(int id) where TEntity : class
      {
          var _dbSet = _context.Set<TEntity>();

          var item = _dbSet.Find(id);

          _dbSet.Remove(item);
          _context.SaveChanges();
      }
  }

Context:

public class ApplicationContext : DbContext
{
public DbSet<Category> Categories { get; set; }

public DbSet<Product> Products { get; set; }

public DbSet<Supplier> Suppliers { get; set; }

public ApplicationContext(DbContextOptions<ApplicationContext> options) : base(options) { }
}

Register context in DI services.AddDbContext<ApplicationContext>(options => options.UseSqlServer(connectionString));
