Inside a visual studio
Tools -> Options -> Debugging -> Symbols -> Verify that the Microsoft Symbol Server is the place to get the symbols from.
Also, on the General tab in the Debugging section, uncheck the Enable only my code box, which will allow me to debug other assemblies.
Also enable the Step Stepping.NET Framework option.
But I would recommend downloading all the characters from the character server and saving them locally.
Then add the path to the local directory as the character path in characters in Visual Studio.
Download characters →
On the Symbols tab in the Debugging section, check the Microsoft Symbol server and click OK. Visual Studio will automatically load characters into the Cache directory
C:\Users\[UserName]\AppData\Local\Temp\SymbolCache
Microsoft Symbol Server Symbol.
