I'm trying to debug a StackOverflow in the EntityFramework NuGet package (version 6.1.3). In order to see the stack frames I need the PDB file for EntityFramework.DLL and EntityFramework.SqlServer.DLL. However, I can't seem to get Visual Studio to download this from either the MSFT symbol sources or from SymbolSource.org (I can get other System PDBs and things like NewtonSoft.json). Are the EF PDBs available anywhere?
Now with pictures (as it took me about an hour of trial and fail)
Get DotPeek from Jetbrains (Standalone version)
Open DotPeek
-> File
-> Open
-> browse to your project bin
folder and open EntityFramework.dll
Right mouse button on EntityFramework
then choose Generate Pdb...
Go to folder where you exported it and open EntityFramework.pdb
folder (I know right!) then dig deeper till you find a file EntityFramework.pdb
and copy it to your bin
folder (next to EntityFramework.dll
).
Go to Visual Studio
-> DEBUG
-> Options and Settings...
-> Symbols
then add your bin
folder to Symbol file (.pdb) locations
Edit: It sometimes starts running EF in optimized
mode that renders debugging pretty much useless which is a whole point of this question - if this happens
Visual Studio
-> Debug
-> General
-> (at the very bottom) Use Managed Compatibility Mode
. Tick and Run project (if it gets optimized then untick and run, then tick again and run, then ....) EF
runs optimized without having to wait till it hits breakpoint Go to Visual Studio
-> Debug
-> Windows
-> Modules
. Then when you run solution modules (2) should appear. Click it and find EntityFramework.dll
there should be column that says Optimized(Yes
= bad, No
= you can debug it).Hope this saves you some time.
Download the source code: entity framework on codeplex
The download button is in the sub-menu on the Source tab
Once downloaded:
Build the solution/project
Navigate to the bin directory NB: it is not in the normal location, its set to "..\..\bin\Debug\"
. See Project properties.
The EntityFramework.pdb and the EntityFramework.SqlServer.pdb are both there.
Also would of thought, it would be available by default or easier.
One of the ways is to use dotpeek as symbol server (load entity framework dll and add dotpeek serer address copied from dotpeek settings) - what is great about this approach, that it generated pdb matching used dll version automatically, what is not so great - it will not contain original comments from source code, etc.
