    Did you add your Employment, EmploymentEducation and Education classes into your dbcontext class? (Like below)

    ...

public DbSet<Employment> Employments {get; set;}
public DbSet<EmploymentEducation> EmploymentEducations {get; set;}
public DbSet<Education> Educations {get; set;}

public DbSet<Employment> Employments {get; set;} 
public DbSet<EmploymentEducation> EmploymentEducations {get; set;} 
public DbSet<Education> Educations {get; set;} 
 
...

    We are using mongodb as database. We are using single class with multiple array :

     public IMongoCollection<EmploymentEducation> EmploymentEducation => Collection<EmploymentEducation>();
 modelBuilder.Entity<EmploymentEducation>(b =>
            {
                b.CollectionName = "EmploymentEducation";
            });

    We are creating this class in domain project

    public ICollection<Employment> Employment { get; set; }
        public ICollection<Education> Education { get; set; }

    and this is what is in domain.shared

     public class Education
    {
        public string SchoolName { get; set; }
        public string Degree_Diploma { get; set; }
        public string Course { get; set; }
        public string GradeAchieved { get; set; }
        public DateTime CourseStartPeriod { get; set; }
        public DateTime CourseEndPeriod { get; set; }
        public DateTime DateOfCompletion { get; set; }
        public string FieldOfStudy { get; set; }
    }
 
    public class Employment
    {
        public string PrevCompanyName { get; set; }
        public string JobTitle { get; set; }
        public string EmploymentPeriod { get; set; }
 
        public string Designation { get; set; }
        public int TotalSalary { get; set; }
        public string References { get; set; }
    }

    Thanks,

    Can you also check your EmploymentEducationRepository class? Is it both inherit from MongoDbRepository<IMyMongoDbContext, EmploymentEducation, Guid> and IEmploymentRepository?

    It's recommended.

    Yes... it worked when we are inheriting both. But the problem is that there is "precompanyname" which is coming from another class (employment)

    How do we use that as this class (Employment) is in Domain.Shared Project? and we are using this class in domain project as a collection.

    (How to access the property of a collection class)

    Here is the code:

    using MongoDB.Driver.Linq; using System; using System.Collections.Generic; using System.Linq; using System.Text; using MongoDB.Driver; using System.Linq.Dynamic.Core; using System.Threading.Tasks; using Volo.Abp.Domain.Repositories.MongoDB; using Volo.Abp.MongoDB; using ZW.EmpSvc.EmploymentEducations; using ZW.EmpSvc.Employments;

    namespace ZW.EmpSvc.MongoDB.EmploymentEducations { public class MongoDbEmploymentEducationRepository : MongoDbRepository<EmpSvcMongoDbContext, EmploymentEducation, Guid> , IEmploymentEducationRepository

    {
    public MongoDbEmploymentEducationRepository(
        IMongoDbContextProvider&lt;EmpSvcMongoDbContext&gt; dbContextProvider
        ) : base(dbContextProvider)
    {
    }

    

    public async Task&lt;List&lt;EmploymentEducation&gt;> GetListAsync(
       int skipCount,
       int maxResultCount,
       string sorting,
       string filter = null
       )
    {

        var queryable = await GetMongoQueryableAsync();
        return await queryable
            .WhereIf&lt;EmploymentEducation, IMongoQueryable&lt;EmploymentEducation&gt;>(
                !filter.IsNullOrWhiteSpace(),
                employment => employment.PreCompanyName.Contains(filter)
            )
            .OrderBy(sorting)
            .As&lt;IMongoQueryable&lt;EmploymentEducation&gt;>()
            //.Skip(skipCount)
            //.Take(maxResultCount)
            .ToListAsync();
    }
}

    }

    Hi again @commitdeveloper1, you can not access directly to precompanyname property because you are keeping Employment as collection instead of class. In other words, you need to iterate to collection to reach its properties.

    public async Task<List<EmploymentEducation>> GetListAsync(int skipCount, int maxResultCount, string sorting, string filter = null)
        {
            var queryable = await GetMongoQueryableAsync();
            return await queryable
                .WhereIf<EmploymentEducation, IMongoQueryable<EmploymentEducation>>(
                            !filter.IsNullOrWhiteSpace(),
                            //you need to iterate collection to reach its properties(prevcompanyname)
                            employment => employment.Employments.Any(x => x.PrevCompanyName.Contains(filter))
                        )
                        .OrderBy(sorting)
                        .As<IMongoQueryable<EmploymentEducation>>()
                                //.Skip(skipCount)
                                //.Take(maxResultCount)
                                .ToListAsync();
        }
