C ＃ using ABP warehouse to access the database error record set

1. Report errors  The JSON value could not be converted to Volo.Abp.Data.ExtraPropertyDictionary.

 1.2 resolvent 1, Add the data contract label in the attribute field DataContract, Data member label DataMember

1.3  Solution 2 , Remove the data label above , Because the original entity class inherits from the collection root AggregateRoot, Change to inherit from Entity , And realize GetKeys Method

because Entity default Id Since the increase , So realize GetKeys When the method is used , This is how to deal with it .

public class UserRole : Entity
{
    public virtual int Id{ get; protected set; }

    public UserRole()
    {
            
    }
    
    public override object[] GetKeys()
    {
        return new object[] { Id };
    }
}

2. The error context instance is released

2.1 resolvent ： Paste an error in the error reporting method of the program  UnitOfWork label

public class MyHandler:ITransientDependency
 {
       [UnitOfWork]
        public async Task HandleEventAsync()
        {
           
        }
 }

  The above basically solves my problems .
