不!Visual Studio没有64位版本。

如何知道它不是64位的: 下载Visual Studio并单击安装按钮后，您将看到它自动选择的初始化文件夹是C:\Program Files (x86)\Microsoft Visual Studio 14.0

根据我的理解，从Windows 7开始，所有64位程序/应用程序都到C:\Program Files，所有32位应用程序都到C:\Program Files (x86)。

微软发布了Visual Studio 2022 64位预览版

由于种种原因，不能。

这篇MSDN文章解释了原因。

First, from a performance perspective the pointers get larger, so data structures get larger, and the processor cache stays the same size. That basically results in a raw speed hit (your mileage may vary). So you start in a hole and you have to dig yourself out of that hole by using the extra memory above 4G to your advantage. In Visual Studio this can happen in some large solutions but I think a preferable thing to do is to just use less memory in the first place. Many of VS’s algorithms are amenable to this. Here’s an old article that discusses the performance issues at some length: https://learn.microsoft.com/archive/blogs/joshwil/should-i-choose-to-take-advantage-of-64-bit Secondly, from a cost perspective, probably the shortest path to porting Visual Studio to 64 bit is to port most of it to managed code incrementally and then port the rest. The cost of a full port of that much native code is going to be quite high and of course all known extensions would break and we’d basically have to create a 64 bit ecosystem pretty much like you do for drivers. Ouch.

不，但32位版本在64位Windows上运行良好。

不，但它在win64上运行良好，并可以创建win64 . exe

Visual Studio 2022是64位的

Windows上的Visual Studio 2022现在是一个64位应用程序。这意味着您可以打开、编辑、运行和调试即使是最大和最复杂的解决方案，而不会耗尽内存。
