In EFCore 2.0 Add new feature, DbContext pooling. i know how to use it in single context, however, sometimes need multi context in project,
public class BContext
Ok. i've found problem. You need to download EF Core, then change constructor for DbContextPool< TContext>
original
public DbContextPool([NotNull] DbContextOptions options)
and change to
otherwise DI will use last added options :)
