How do I debug .NET 4.6 framework source code in Visual Studio 2017?
问题 Here's what I've tried: Made a new Console App (.NET Framework) in Visual Studio 2017. Added the following code: static void Main(string[] args) { new Dictionary<int, int>().TryGetValue(3, out int x); //I want to step into TryGetValue() (this is just an example) } Configured the settings listed here: https://blogs.msdn.microsoft.com/sburke/2008/01/16/configuring-visual-studio-to-debug-net-framework-source-code/ Confirmed symbols are loaded in the Modules window: mscorlib.dll Symbols loaded. 4
