Still, even updating a dozen extensions in Visual Studio Code takes much less time than Visual Studio used to take to rebuild the symbol tables of a large C++ project. I said usually, not always: Visual Studio Code itself needs a monthly update, and the many extensions I have installed often need their own updates. Meanwhile, Visual Studio Code usually starts up quickly enough that I can be productive in a few minutes, even for large projects. It’s now a non-issue even in huge Visual Studio 2022 projects. The startup overhead of Visual Studio has decreased significantly over the years, by the way.

When I worked on a C++ project with ~2 million lines of code, I also jump-started each day’s work by automatically running a batch script that did a code checkout and full rebuild of the product in the wee hours. I would keep the IDE open all day as I went through develop/test/debug cycles to avoid another startup delay. The goal is to preserve the projects in their current state for long-term archive and testing purposes.For decades, when I got to work in the morning, I would start Microsoft Visual Studio (or one of its predecessors, such as Visual C++ or Visual InterDev), then brew tea and possibly attend a morning meeting while it went through its laborious startup. Note: Updating the projects to 4.8 is not what I want here. What changed, and how do I open these 4.5 Framework projects in VS?

I've tried installing the 4.5 runtime and a few of the newer ones, and I installed the 4.5.1 Developer Pack, but it's not helping. NET Framework 4.5 targeting pack', it opens a browser and sends me here, but I'm not sure what it's expecting me to install. These projects were just opening and executing as late as last night. It has never done this before, and nothing has been removed from my computer. NET Framework 4.5 projects and keeps showing this dialog.

Suddenly starting today VS2022 won't open my.
