当我从this example执行SP CLR时，在SQL Server版本11.0.3128（基本上是2012 + SP1）上，有时我得到以下错误，有时没有：
Msg 6522, Level 16, State 1, Line 1
A .NET Framework error occurred during execution of user-defined routine or aggregate "XMLTest":
System.InvalidOperationException: Cannot load dynamically generated serialization assembly.

我的问题是：为什么它不会附加到所有SQL Server 11.0.3128中？我有两个客户使用相同的版本，一个遇到问题而另一个没有。
我查了一下：
我知道sgen.exe的解决方法（如链接中所述），但我想了解为什么此服务器的行为与其他服务器的行为不同，我是否在某个地方错过了设置？ Thx提前。
