如何构建64位asp.net项目？

我创建了一个新项目build and run，它要求我修改web.config进行调试，我单击了yes。这辆车很好。我将目标cpu从任意位切换到64位，结果出现异常。如何构建和运行64位项目

您可以将目标cpu保留在“Any”上，这将适用于32位和64位系统

（从错误消息判断，似乎您尝试运行它的实际上不是64位系统。）

如果将目标指定为“x64”，则编译的目标仍然完全相同。唯一的区别是程序集具有一个标志，该标志将其限制为仅在64位系统上使用

基本上，将程序集限制为64位的唯一原因是，如果您使用的是为64位系统编译的非托管库。

奇怪。但这又有什么关系呢。我已经安装了win7。我需要一个单独的框架吗。IIRC我使用的是visual studio 2008 proinstall@acidzombie24：也可能是您在32位模式下运行IIS。（如果你也在it框架1.1中运行web应用程序，这是必需的。）@o.k.w：我认为你是对的。哈哈。它的Visual Studio Web服务器。我不知道如何更改它，但可能是因为它没有64位框架吗？@acidzombie24:visualstudio是一个32位的应用程序，它的内部web服务器也是如此。因此，它的工作方式与32位模式下的IIS类似。您需要以64位模式运行的完整版本IIS才能运行64位web应用程序。奇怪。但这又有什么关系呢。我已经安装了win7。我需要一个单独的框架吗。IIRC我使用的是visual studio 2008 proinstall@acidzombie24：也可能是您在32位模式下运行IIS。（如果你也在it框架1.1中运行web应用程序，这是必需的。）@o.k.w：我认为你是对的。哈哈。它的Visual Studio Web服务器。我不知道如何更改它，但可能是因为它没有64位框架吗？@acidzombie24:visualstudio是一个32位的应用程序，它的内部web服务器也是如此。因此，它的工作方式与32位模式下的IIS类似。您需要以64位模式运行的完整版本IIS才能运行64位web应用程序。
