Description

On https://msdl.microsoft.com/download/symbols, symbols are available for x86 and x64 Windows, but are missing for ARM64 Windows with the following binaries:

  • clrgc.dll
  • clrjit.dll
  • coreclr.dll
  • createdump.exe
  • mscordaccore.dll
  • mscordaccore_arm64_arm64_8.0.1224.60305.dll
  • mscordbi.dll

They are present for 8.0.11, but missing for 8.0.12.

Reproduction Steps

Download the Windows ARM64 runtime artifacts for 8.0.12 (and 8.0.11 for comparison):

Extract coreclr.dll from the shared\Microsoft.NetCore.App\8.0.12 (or 8.0.11) folder.

Get symchk.exe from the debugging tools for Windows. (https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/using-symchk)

Run this command while in the folder that contains coreclr.dll:
symchk.exe /s SRV*https://msdl.microsoft.com/download/symbols /if coreclr.dll /oc . /v

The output will show the PDB is missing from the symbol server for 8.0.12:

Expected behavior

Symbols for Windows ARM64 native binaries in 8.0.12 should be published to https://msdl.microsoft.com/download/symbols.

Actual behavior

Symbols for Windows ARM64 native binaries in 8.0.12 are missing on https://msdl.microsoft.com/download/symbols, although they are present for x86 and x64, and for the ARM64 build of 8.0.11.

Regression?

Yes, the symbols are available for 8.0.11.

Known Workarounds

If you are a Microsoft employee, you can point to the Microsoft-internal symbol server instead. The Windows ARM64 binaries for 8.0.12 are present on the Microsoft-internal symbol server.
