Question

在中等信任环境中使用Unity + Fluent NHibernate + NHibernate 3.3.1.4

var session = sessionFactory.OpenSession();

返回此错误：

Attempt by method 'NHibernate.AdoNet.SqlClientSqlCommandSet..ctor()' to access method 'System.Data.SqlClient.SqlCommandSet..ctor()' failed.

有人可以帮助我吗？

这是一个非常容易解决的问题。您必须禁用批处理。您可以通过将属性adonet.batch_size设置为0

来执行此操作

在hibernate.cfg.xml / App.config的{{1}}或nhibernate配置部分中：

Web.config

或者是FluentNHibernate：

<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <reflection-optimizer use="false"/>
  <session-factory>
    <!-- other properties -->
    <property name="adonet.batch_size">0</property>
  </session-factory>
</hibernate-configuration>
