Question

我有一个在VS2008中构建的WCF服务当我发布服务并在IIS中运行它（在应用程序池中启用32位应用程序）然后很好，它的工作原理。但是当我尝试调试应用程序时（所有项目的平台目标都是任何CPU），我收到以下错误：

Common Language Runtime detected an invalid program.

Description: An unhandled exception occurred during the execution of the current web     request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.InvalidProgramException: Common Language Runtime detected an invalid program.

Source Error:

   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +344
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +557

这个错误是什么意思？任何帮助都非常感谢

您的开发平台 32位，您部署的平台为64 bit。选择调试类型 AnyCPU 程序集在加载到64 bit进程时将JIT转换为 64位代码，而32 bit加载到32 bit时处理。已发布的汇编/从属程序集很可能与64位不兼容，需要处于32位进程。
