The exception to this is when you are debugging managed (.NET) applications, the debugger will not load symbols for any binaries considered “not your code” when “Just My Code” is enabled.

Visual Studio will try to load symbols for all binaries (referred to as “modules”) in the process when the module is loaded (and for all modules already loaded when attaching to a process).

Said another way, if you are debugging a dump with no heap information, you need both the corresponding binary and symbol file on the symbol path.īefore we look at any of Visual Studio’s advanced settings it’s important that I stop and review the default behavior (meaning if you never touch a setting how will it behave):

Note: If you are debugging a dump file that does not contain the heap, the debugger will need access to the original binary file so it can determine the correct symbol file to load.

Depending on what you are debugging, symbols may be required to show you a complete call stack and to inspect objects using the Watch windows, or DataTips (e.g.

If symbols are not loaded you will see a hollow circle with a warning symbol while in debug mode, and if you hover the mouse over it a tooltip will tell you that the breakpoint will not be hit because no symbols have been loaded.

When debugging, without a symbol file you are unable to set breakpoints on a specific line of code.

Why do I need symbols? Without symbols, tools are unable to correlate the instructions executing in the application to the original source code.

What is in a symbol (.pdb) file? The exact contents of symbol files will vary from language to language and based on your compiler settings, but at a very high level they are the record of how the compiler turned your source code into machine code that the processor executes.pdb files that are produced as part of your build. What is a symbol file? For the Microsoft compilers, these are the.Symbol basicsīefore we delve into the details of symbol files it’s important to briefly review what symbols are and why they are important:

In this blog post I’ll walk you through what symbols are and how to configure Visual Studio’s symbol settings (which are used by other diagnostic tools beyond the debugger such as the performance tools and IntelliTrace), the various knobs available when debugging, and how to trouble shoot issues when Visual Studio isn’t able to find the symbol files that you need. Additionally because symbols are so fundamental to debugging, we continue to make tweaks to the experience so understanding the ins and outs of how Visual Studio behaves can save you hours of frustration. However the odds are that at some point in time you’ll need to change how symbols load, where the debugger looks for them, or will need to load symbols for a 3 rd party component (e.g. Fortunately in most cases when you are building and launching your application in Visual Studio you don’t have to think about symbols for your code. Symbols are a fundamental requirement for debugging and other diagnostic tools.
