Overcoming Slow Performance in Visual Studio 2022 with ReSharper

As a developer, there's nothing more frustrating than experiencing slow performance issues in your development environment. In recent updates of Visual Studio (VS) 17.2/2022.1.1, I encountered similar problems that were attributed to a particular NuGet package. After some investigation and experimentation, I was able to identify the culprit and resolve the issue.

Prior to installing this package, my setup was running smoothly with no issues related to slow performance or memory allocation. However, once I removed it from my project, everything returned to normal. Not only did the allocations drop significantly, but full analysis on large files also became much faster without causing excessive memory usage (peaking at around 6-8 GB temporarily before dropping back down to 3 GB).

One of the most significant advantages of this solution was that repeated builds no longer froze my system. Furthermore, the UI no longer experienced extreme stucks, even when the CPU was under moderate load and file access wasn't blocked.

Upon further investigation, I discovered that the issue was likely caused by source generators installed as part of the package CommunityToolkit.Mvvm in Version 7.12. This package not only installed MVVM analyzers but also added unnecessary dependencies to every project in my solution, including static asset libraries.

Interestingly, it seems that there is a bad synergy between VS 17.2, ReSharper 2022.1.1, and this particular NuGet package. When I first started profiling Visual Studio under the Resharper verbose logging command, I noticed some alarming statistics: nearly 60 GB of memory allocation within the first minute after starting and opening my solution, followed by 10 seconds of UI freeze and nearly 20% CPU time consumed by the garbage collector.

In conclusion, while ReSharper may have been initially suspected to be the cause of slow performance, it was actually a combination of factors that contributed to this issue. By removing the problematic NuGet package and understanding the underlying causes, I was able to resolve the problem and enjoy a smoother development experience once again.
