Each\n  command still gets its own `\u002Fbl:{}` so the logs never overwrite each other.\n\n```bash\ndotnet build -c Debug   \u002Fbl:{}   # unique file\ndotnet build -c Release \u002Fbl:{}   # another unique file\n```\n\n## Verify the binlog exists\n\nAfter the build, confirm a `.binlog` was actually produced before moving on to\nanalysis — a build that fails *before* MSBuild starts (e.g. a bad argument)\nwrites no binlog:\n\n```bash\nls -1 *.binlog       # bash\ndir \u002Fb *.binlog      # Windows cmd\n```\n\n```powershell\nGet-ChildItem *.binlog   # PowerShell\n```\n\nNote the resulting path so `binlog-failure-analysis` or `build-perf-diagnostics`\ncan consume it.\n\n## When a Specific Filename Is Required\n\nIf the binlog filename needs to be known upfront (e.g., for CI artifact upload), or if `{}` is not available in the installed MSBuild version, pick a name that won't collide with existing files:\n\n1. Check for existing `*.binlog` files in the directory\n2. Choose a name not already taken (e.g., by incrementing a counter from the highest existing number)\n\n```bash\n# Example: directory contains 3.binlog — use 4.binlog\ndotnet build \u002Fbl:4.binlog\n```\n\n## Cleaning the Repository\n\nWhen cleaning the repository with `git clean`, **always exclude binlog files** to preserve your build history:\n\n```bash\n# ✅ CORRECT - Exclude binlog files from cleaning\ngit clean -fdx -e \"*.binlog\"\n\n# ❌ WRONG - This deletes binlog files (they're usually in .gitignore)\ngit clean -fdx\n```\n\nThis is especially important when iterating on build fixes - you need the binlogs to analyze what changed between builds.\n",{"data":35,"body":36},{"name":4,"description":6,"license":25},{"type":37,"children":38},"root",[39,48,69,76,89,161,175,196,208,294,302,335,341,385,391,590,596,622,637,704,710,731,791,805,825,831,843,864,895,901,921,1005,1010],{"type":40,"tag":41,"props":42,"children":44},"element","h1",{"id":43},"generate-binary-logs",[45],{"type":46,"value":47},"text","Generate
