: Allows developers to apply code changes during debugging without restarting the application or losing its state. Modernized UI

Prior to this, Visual Studio 2019 and earlier versions were 32-bit applications, limited to 4 GB of virtual address space (and effectively less due to fragmentation). In modern development, this limitation was a significant bottleneck. Solutions grew to include hundreds of projects, complex codebases, and advanced features like Live Share and IntelliCode, constantly pushing against that 4 GB ceiling. The result was frequent Out-Of-Memory (OOM) errors, sluggish performance when working with large solutions, and an inability to leverage the full power of modern machines with 32+ GB of RAM.

With the release of , Microsoft fundamentally rewired its flagship IDE. The headline feature, as emphasized in the keyword "Visual Studio 2022 64 bits" , is that the main devenv.exe process is now a native 64-bit application.

Visual Studio 2022 is a 64-bit version of the popular integrated development environment (IDE) from Microsoft. Unlike its 32-bit predecessors, Visual Studio 2022 64 bits is designed to take full advantage of 64-bit Windows operating systems, offering improved performance, stability, and scalability.
