How to collect a WinDbg dump of a Visual Studio crash

Install WinDbg

Run winget install Microsoft.WinDbg, or follow the steps in Install WinDbg from Microsoft.

Record a crash log

1. Create the C:\logs\ and C:\dump\ folders.
2. Start Visual Studio.
3. Start WinDbg.
4. Press F6 and attach to the devenv.exe process.
5. Enter these commands one by one:

   sxd av
   .logopen /t c:\logs\Output.txt

6. Press F5 to resume Visual Studio.
7. Reproduce the crash.
8. When Visual Studio crashes, enter these commands one by one:

   .loadby sos clr
   !PrintException
   !ClrStack
   ~* e !ClrStack
   ~* k

9. Enter .logclose to save the log. The log file is in C:\logs\, and its name starts with Output.

Save a dump file

If JetBrains support asks for a dump file, enter one of these commands after step 8.

For a mini dump:

.dump /mdhiptu c:\dump\windbg_crash_dump.dmp

For a full dump:

.dump /map c:\dump\windbg_crash_fulldump.dmp

Send the files

Upload the log file, the dump file, and sos.dll from your machine to uploads.jetbrains.com, then share the Upload ID with JetBrains support. For Visual Studio 2022 and later, sos.dll is in C:\Windows\Microsoft.NET\Framework64\v4.0.30319\. For Visual Studio 2019 and earlier, it is in C:\Windows\Microsoft.NET\Framework\v4.0.30319\.
