从Visual Studio 2010中发布报表错误-”Loading this assembly would produce a different grant set from other instances“

  • Article

 

问题描述:

从Dynamics AX 2012 R2 的AOT / Visual Studio Projects/ 打开一个VS.NET 报表项目，这样VS.NET就打开了，编译部署该报表报如下错误:

The "GenerateRdlTask" task failed unexpectedly.

System.IO.FileLoadException: Loading this assembly would produce a different grant set from other instances. (Exception from HRESULT: 0x80131401)

   at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck)

原因:

“Loading this assembly would produce a different grant set from other instances”是一常见错误，从CLR角度来看是如下assembly 被加载到多个AppDomain中，而security context不同:

Microsoft.Dynamics.Framework.ReportsDeployment, Version=6.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35

AX 定制了一个单独的VS.NET project template, 在发布项目时候为了实现能够unload/load 会建立一个临时的AppDomain, 调用AppDomain.CreateIntanceAndUnWrap()执行 Microsoft.Dynamics.Framework.ReportsDeployment.dll中的类型：

Microsoft.Dynamics.Framework.Deployment.Reports.DomainBoundHelper

深层次的原因目前不清楚，目前只在一个客户那里发生该问题，无法在内部重现跟踪排错。

如果用Process Explore查看DevEnv.exe (VS.NET)加载的assembly, 可以看到Microsoft.Dynamics.Framework.ReportsDeployment.dll被加载到多个AppDomain中，包括Shared AppDomain. 但是Microsoft.Dynamics.Framework.ReportsDeployment.dll实际上是被安装到GAC里的，而且有强签名的，所以不应该会出现在多个AppDomain中的。

解决办法：

目前来看可以采用如下办法绕过该问题:

设置操作系统级别的环境变量 COMPLUS_LoaderOptimization =1， 关于COMPLUS_LoaderOptimization 的说明参看

    Thanks for your post. Your workaround has just been used by a customer in EMEA! Any progress for a complete fix?
