Using dbhelp we can get the size of the public symbol / function. SharpPdb only provides the RVA but not the size. Is there a way to get the size somehow?

PDB symbols seem to have the incorrect RVA (or maybe the RVA is different from the one I'm expecting.)

Here is a comparison between the RVA calculated using the dbghelp Win32 functions and the RVA from SharpPdb:

PDB file: clr.pdb

Symbol: g_pGCHeap

RVA from dbghelp: A17038

RVA from SharpPdb: A25A60

0:000> dt _LIST_ENTRY
ntoskrnl!_LIST_ENTRY
+0x000 Flink : Ptr64 _LIST_ENTRY
+0x008 Blink : Ptr64 _LIST_ENTRY

How can I know there are two pointers in _LIST_ENTRY?

I would like to use this as a replacement for dbghelp. But I'm struggling with getting the export symbols from system modules such as Kernel32.dll. Dbghelp has no issues with these files, even when I'm offline (its not downloading any pdb files from the internet). Any idea?

Can you enable symbol package (.snupkg) creation and publishing for the SharpPdb nuget package - see here

Hey @southpolenator
I hope you are still somehow around and maintaining this project. I was planning to use SharpPdb instead of the Native DIA COM interface as it is super slow and the type model exposed by SharpPdb is very useful.

Unfortunately I noticed that a lot of user defined types are missing when loading my PDB and a lot of them are essential for my purpose.

Unfortunately I cannot share the related binaries but I was wondering if you have some ideas on how I could troubleshoot this. One of the missing type is a simple C# class with various members and a base class, nothing special about it.

I wonder if my PDB is an unsupported version? I noticed that there are 2 "TypeLeafKinds" with many records in the TpiStream:

If I count the DIA symbols by GetUdtKind() I get those numbers:

If I count the PdbSharp TypeRecords by TypeLeafKind I get those numbers with many classes less:
