问题描述
在godaddy上使用实体框架时,我们得到一个SecurityException
.已针对MySQL存储区配置了该实体. (v.6.1.2)但是,异常有点怪异……查看异常堆栈似乎暗示着,如果我们在站点的任何地方打开与MySQL的连接,那么我们应该得到相同的异常.但是,直接打开MySQL连接似乎在网站的另一部分中起作用.
We are getting a SecurityException
when using Entity framework on godaddy. The entity has been configured against a MySQL store. (v. 6.1.2) A bit of weirdness with the exception though... Looking at the exception stack it seems to imply that if we open up a connection to MySQL anywhere in the site, then we should get the same exception; however, opening up a MySQL connection directly seems to be working in another part of the site...
这是验证:
using (MySqlConnection connection = new MySqlConnection(ConnectionString))
{
connection.Open();
...
}
有人遇到类似的问题吗?
Anyone run across a similar issue?

推荐答案
Justin被发现了.问题是Godaddy在其gac中有一个较旧版本的MySql dll,而实体框架正在将其拾取!
Justin was spot on. Problem was godaddy has an older version of the MySql dll in their gac and the entity framework was picking it up!
解决了. (将此应用到web.config)
Here's the fix. (Apply this to web.config)
<configuration>
...
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="MySql.Data" publicKeyToken="c5687fc88969c44d"/>
<bindingRedirect oldVersion="5.0.7.0" newVersion="6.1.2.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
...
</configuration>
