你好，
我有一个asp.net Web API。我正在使用EF 6代码优先方法。仅当我使用Jmeter对Web API进行负载测试时，才出现此错误。我怎样才能解决这个问题？
这是我的GameResponse：

The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: Saving or accepting changes failed because more than one entity of type 'BusinessEntity.GameResponse' have the same primary key value. Ensure that explicitly set primary key values are unique. Ensure that database-generated primary keys are configured correctly in the database and in the Entity Framework model. Use the Entity Designer for Database First/Model First configuration. Use the 'HasDatabaseGeneratedOption" fluent API or 'DatabaseGeneratedAttribute' for Code First configuration这是我的GameResponse：
C#:
using System;

因为没有其他方法可以想到在插入时获取referenceId。
