Visual Studio反复弹出ReSharper性能配置提示的技术咨询

Hey there, let's work through your Visual Studio + ReSharper performance prompt headaches together! I'll break down both your questions clearly below:

ReSharper is a powerful tool, but its deep integration with VS can strain resources under certain conditions. Here are the most common culprits:

• Large solution/project counts: If your solution has dozens (or hundreds) of projects, ReSharper has to index every single file during startup and ongoing use. This eats up CPU and memory, triggering the performance alert.
• Broad real-time code analysis: By default, ReSharper runs constant checks for code issues, refactoring suggestions, and even analyzes third-party library code if enabled. This continuous background processing can bog down VS, especially on less powerful machines.
• Version control integration clashes: When ReSharper's version control features overlap with VS's built-in source control plugin (like Git or TFS), background syncs and status checks can create resource conflicts—especially with large repositories.
• Corrupted or oversized caches: ReSharper uses caches to speed up load times, but if these files get corrupted or grow too large, they can slow down startup instead of helping, leading to the performance prompt.
• Conflicts with other VS plugins: If you have other tools (like code formatters, test runners, or linters) installed alongside ReSharper, they compete for the same system resources, worsening overall performance.

Your ignore setting might not be addressing the root cause, or there could be a configuration glitch at play:

• Setting didn't save or take effect: Sometimes, ReSharper's configuration files (like .DotSettings) can become corrupted, or VS might not persist the change properly. Try closing and reopening VS after setting the ignore, or even resetting ReSharper's settings to default temporarily.
• The prompt is triggered by other issues: The "Configure settings to improve performance" alert isn't only tied to version control. If other performance bottlenecks (like the large solution size or cache issues mentioned above) are still present, the prompt will keep appearing regardless of your version control ignore setting.
• Compatibility bugs in your version combo: ReSharper 2017.3.1 and VS 2017 15.5.2 are older versions, and there might be known bugs where the performance prompt logic doesn't respect the ignore setting. JetBrains might have patched this in later updates for your ReSharper version.
• VS native settings overriding ReSharper: VS has its own performance-related settings (like auto-loading solutions or real-time compilation) that could be interacting with ReSharper's setup, causing the prompt to reappear even after your ReSharper tweak.

Quick fixes to try #

If you want to get rid of the prompt for good, here are some actionable steps:

• Clear ReSharper's cache: Go to ReSharper > Options > Environment > General and click "Clear Caches", then restart VS. This fixes many performance issues caused by bad cache data.
• Narrow ReSharper's analysis scope: In ReSharper > Options > Code Inspection > Settings, disable analysis for third-party assemblies and limit checks to only your active projects.
• Update ReSharper to the latest patch for 2017.3.x: Even if you don't want to upgrade to a newer major version, installing the latest patch for your release might fix the prompt persistence bug.
• Disable unnecessary VS plugins: Go to Tools > Extensions and Updates and turn off any plugins you don't use regularly to reduce resource competition.
