背景
- 我有一个包含控制台项目和MVC4 Web应用程序的解决方案。
- 两者都引用了Oracle.ManagedDataAccess（托管的ODP.NET数据访问提供程序）。引用是相同的文件。
- 没有引用Oracle.ManagedDataAccess DTC。
- 在VS配置管理器中，所有配置选项的平台都列为“Any CPU”。
- 两个项目的平台目标都是“Any CPU”。
问题
控制台应用程序可以完美地执行。
当我尝试使用MVC4应用程序时，我看到：
Could not load file or assembly 'Oracle.ManagedDataAccessDTC' or one of its dependencies. An attempt was made to load a program with an incorrect format.
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 'Oracle.ManagedDataAccessDTC' or one of its dependencies. An attempt was made to load a program with an incorrect format.
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 'Oracle.ManagedDataAccessDTC' could not be loaded.
=== Pre-bind state information ===
LOG: User = [Redacted]\killesj1
LOG: DisplayName = Oracle.ManagedDataAccessDTC
(Partial)
WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: Oracle.ManagedDataAccessDTC | Domain ID: 13
WRN: A partial bind occurs when only part of the assembly display name is provided.
WRN: This might result in the binder loading an incorrect assembly.
WRN: It is recommended to provide a fully specified textual identity for the assembly,
WRN: that consists of the simple name, version, culture, and public key token.
WRN: See whitepaper http://go.microsoft.com/fwlink/?LinkId=109270 for more information and common solutions to this issue.

我应该注意到，我知道这是Oracle.ManagedDataAccess DLL的32位和64位版本之间的问题。
然而，为什么针对同一DLL并使用相同设置编译的两个项目在工作方面会有不同的结果呢？
到目前为止，我尝试了以下方法： - 为了好玩，从IIS Express切换到Cassini...但是问题仍然存在。 - 尝试使控制台应用程序以同样的方式失败...但目前还没有成功。
