NetCore + Mysql + EF:No coercion operator is defined between types 'System.Int16' and 'System.Boolean',

总结三种解决办法：

1.Mysql升级到7

2.Nuget安装Pomelo.EntityFrameworkCore.MySql 2.2.0替代MySql.Data.EntityFrameworkCore 8.0.16后正常.

PS：如果使用Pomelo库的SQL语句查询Convert.ToDateTime(item["createtime"]).ToString("yyyy-MM-dd HH:mm:ss")会报Unable to cast object of type 'MySql.Data.Types.MySqlDateTime' to type 'System.IConvertible'.  要改成Convert.ToDateTime(item["dskuupdatetime"].ToString()).ToString("yyyy-MM-dd HH:mm:ss").

3.EF上下文添加转换代码

 protected override void OnModelCreating(ModelBuilder builder)
 {
             base.OnModelCreating(builder);

             foreach (var entityType in builder.Model.GetEntityTypes())
             {
                 foreach (var property in entityType.GetProperties())
                 {
                     if (property.ClrType == typeof(bool))
                     {
                         property.SetValueConverter(new BoolToIntConverter());
                     }
                 }
             }
 }

 public class BoolToIntConverter : ValueConverter<bool, int>
     {
         public BoolToIntConverter( ConverterMappingHints mappingHints = null)
             : base(
                   v => Convert.ToInt32(v),
                   v => Convert.ToBoolean(v),
                   mappingHints)
         {
         }

         public static ValueConverterInfo DefaultInfo { get; }
             = new ValueConverterInfo(typeof(bool), typeof(int), i => new BoolToIntConverter(i.MappingHints));
     }

PS: Linq Any转换失败：

　　　　var isExist = db.MyDbTable.Any(o => o.Id == id);

　　　　//throw No coercion operator is defined between types 'System.Int16' and 'System.Boolean',

              要改成

              var isExist = db.MyDbTable.FirstOrDefault(o => o.Id == id) != null;

     对于Linq Any有其他解决办法吗？
