Ignite 2.16 - Multiple query fields are associated with the same alias

[Charlin S]

Hi All,
I am upgrading Ignite from 2.10 to 2.16 and getting Multiple query fields
are associated with the same alias error for *EMPCode* and *EmpName, *which
is working with Ignite 2.10. unable to create Employee cache.

Error 1:
System.Exception: IgniteException for chache ::  Employee
 ---> Apache.Ignite.Core.Cache.CacheException: class
org.apache.ignite.IgniteCheckedException: Multiple query fields are
associated with the same alias [alias=EMPNAME]

Error 2:
  System.Exception: IgniteException for chache ::  Employee
 ---> Apache.Ignite.Core.Cache.CacheException: class
org.apache.ignite.IgniteCheckedException: Multiple query fields are
associated with the same alias [alias=EMPCODE]

Error 2 can be corrected by removing TmcCode property but why same error
for EmpName?

my class file
Public class Employee: IBinarizable
{
        [QuerySqlField]
        public string EMPCode { get; set; }
        [QuerySqlField]
        public string EmpCode { get; set; }
        [QuerySqlField]
        public string EmpName { get; set; }
        [QuerySqlField]
        public EmpInfo EmpInformation { get; set; }

        public void WriteBinary(IBinaryWriter writer)
        {
            if (writer != null)
            {
                writer.WriteString("empcode", EMPCode);
                writer.WriteString("empname",  EmpName );
                writer.WriteObject(" empInformation",  EmpInformation   );
            }
        }
         public void ReadBinary(IBinaryReader reader)
        {
            if (reader != null)
            {
                 EMPCode = reader.ReadString("empcode");
                 EmpName = reader.ReadString("empname");
                  EmpInformation     = reader.ReadString(" empInformation");
            }
         }
   }

  public class EmpInfo : IBinarizable
  {
        [QuerySqlField]
        public string EmpName { get; set; }
        [QuerySqlField]
        public string EmpAddress{ get; set; }

       public void WriteBinary(IBinaryWriter writer)
        {
            if (writer != null)
            {
                writer.WriteString(" empname  ",  EmpName   );
                writer.WriteString(" empaddress  ",   EmpAddress  );
            }
        }
         public void ReadBinary(IBinaryReader reader)
        {
            if (reader != null)
            {
                  EmpName   = reader.ReadString(" empname  ");
                  EmpAddress  = reader.ReadString(" empaddress  ");
            }
         }
  }
