服务器错误：无法加载程序集

Question

这是我第一次尝试在 aspx.net 中构建项目，但我不知道如何解决这个问题。 我正在尝试创建一个与 Dynamics CRM Online 实例对话的网站。 我尝试与我的托管服务提供商交谈，他们说我的 web.config 需要更正。 错误页面是：

 Could not load file or assembly 'microsoft.crm.sdk.proxy' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
 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.BadImageFormatException: Could not load file or assembly 'microsoft.crm.sdk.proxy' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

 Source Error:

 An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

 Assembly Load Trace: The following information can be helpful to determine why the assembly 'microsoft.crm.sdk.proxy' could not be loaded.


 WRN: Assembly binding logging is turned OFF.
 To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
 Note: There is some performance penalty associated with assembly bind failure logging.
 To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Answer 1

我知道这已经过时了，但它在 Google 上的排名很高，所以我将分享我的解决方案。确保在 CRM dll 或任何加载 CRM dll 的项目的应用程序池上将启用 32 位应用程序设置为 True。

Answer 2

尝试删除bin目录下的文件microsoft.crm.sdk.proxy.dll并重建。 它对我有用。

Answer 3

Here 描述了如何在 .Net 中启用 FUSION 登录。实际上，您在错误消息中有此建议。比您在日志中的详细说明无法加载哪些程序集。
