this is program.cs file

as I understand it, it cannot create a UnitOfWork because it does not know how to make an Office.DataAccess.ApplicationDbContext but you do register the context successfully the ApplicationDbContext added to the services in Program.cs is 100% Office.DataAccess.ApplicationDbContext?

mer_nam hai bulla rakhta hu kulaOP•3y ago

yes

Tvde1•3y ago

delete /bin and /obj and run again? 😬 And where is it trying to create a IUnitOfWork?

mer_nam hai bulla rakhta hu kulaOP•3y ago

mer_nam hai bulla rakhta hu kulaOP•3y ago

here it is invoking applicationDbcontext in unitofwork

Tvde1•3y ago

yeah but usually the error would also show that e.g. a controller requires IUnitOfWork

Office.rar

here this is the project file see if you can solve

Your dbcontext seems to inherit from IdentityDbContent. But you haven't specified the IdentityUser. Try this

public class ApplicationDbContext: IdentityDbContext<IdentityUser>
{
  public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
  {
  }
// Add your DbSet's
}

public class ApplicationDbContext: IdentityDbContext<IdentityUser>
{
  public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
  {
  }
// Add your DbSet's
}

Just a tips, don't use UnitOfWork. It's already kindof implemented in ef. Also don't make your dbsets nullable If you don't like the warning that it gives do something like this

public DbSet<Emp> Employees => Set<Emp>();

public DbSet<Emp> Employees => Set<Emp>();

Tvde1•3y ago

yeah building a repository atop of EF while still exposing its SaveChanges or IQueryable<T> is a pretty bad design pattern. It abstracts nothing and only limits the use of EF

v0fbu1vm•3y ago

Definitely!

@SwaggerLife @Tvde1 thanks for input guys but this error is solved+ after posting this question in multiple servers for the error everyone discouraged me for those repository implementation next time I will keep this in mind

Tvde1•3y ago

it's still good to practice and write code :)
