Not sure which assembly I should reference to, to remove this blocking error.
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddDbContext<QAContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
// Add framework services.
services.AddMvc();
}
Error CS1061 'DbContextOptionsBuilder' does not contain a definition for 'UseSqlServer' and no extension method 'UseSqlServer' accepting a first argument of type 'DbContextOptionsBuilder' could be found (are you missing a using directive or an assembly reference?)
If you are using EntityFrameworkCore you must:
Add to Reference:
Microsoft.EntityFrameworkCore.SqlServer
Add to source file:
using Microsoft.EntityFrameworkCore;
First go to toolbar > Tools > NuGet Package Manager > Package Manager Console, And it will be open below type "Install-Package Microsoft.EntityFrameworkCore.SqlServer" and it will solved.
