  • what does not work? Give more information (and error messages if you get them) – magicandre1981 May 18 '16 at 15:25
  • :) `List a = new List() {"2", "1"}; a.Sort();` when I hit f11 at 'a.Sort();', VS2015 did not step into the source code of 'Sort' method. So, I mean it does not work. – John May 19 '16 at 01:19
  • have you uncheck **Just my code**? Also don't point to the public MS symbol server, they don't include source information. – magicandre1981 May 19 '16 at 04:23
  • :) of course I unchecked **Just my code**, also I did not point to **Microsoft symbol server**, but when I run my app, VS2015 starts to download symbols from **Microsoft symbol server**, when it is finished, I still can not step into .Net source code. Maybe you can try it yourself. – John May 19 '16 at 04:54
  • Microsoft symbol server hosts public symbols and this is why it doesn't work. Have you configured the environment variable **_NT_SYMBOL_PATH** and configured here the MS Symbol server? – magicandre1981 May 19 '16 at 15:33

  • It is the familiar problem I described in the linked Q+A. You have the same version of mscorlib.dll on your machine as I do. It got delivered through Windows Update on my machine on April 22nd. This breaks the reference source, that server is not updated automatically from the build server like the msdl server is and it still has the old PDBs. It can take a while before somebody wakes up and takes care of it. You are stuck until that happens. – Hans Passant May 22 '16 at 08:52
  • @HansPassant Hope MS could solve this. :) – John May 22 '16 at 09:05
  • Hmya, SO is not the Microsoft Support email inbox. You got the ear of a Microsoft employee who never heard of this problem, not exactly the most efficient way to go about it. I'm closing this as dup, clearly it is. – Hans Passant May 22 '16 at 09:14

Update: it looks like this is a problem on the Microsoft server side. The symbols for

http://referencesource.microsoft.com/symbols/mscorlib.pdb/f0736c7e93844f56b40982538de2d7312/mscorlib.pdb

haven't been published yet. I'm confirming internally and will update here once the team responds.

This can happen when you first loaded public symbols (without source code mappings) from Microsoft Symbol Server, they got cached in the SymbolsCache folder, then you turned off public symbol server, however the old symbols still get picked up from the cache.

Try deleting this folder: C:\Users\HaoPeng\AppData\Local\Temp\SymbolCache And try again.

  • I delete the folder and open the solution, then VS starts to Load symbols from: Microsoft Symbol Servers(a dialog shows up), when this is done, I click Start to run the demo, and VS starts to Downloading public symbols(another dialog shows up), when this is done, I still can not step into .net source code. – John May 22 '16 at 02:27
  • Could you please delete the folder again, then paste the Symbol load info for mscorlib.dll? – Kirill Osenkov May 22 '16 at 07:55
  • :) OK, I pasted the load info at 'EDIT2' above. Because it's too long to be a comment. – John May 22 '16 at 08:22
  • It looks like a problem on Microsoft side - symbols for f0736c... (NETFXREL3STAGE) haven't been published yet. Once I know more I will post more. – Kirill Osenkov May 22 '16 at 08:30
