The Watch window has three columns: Name, Value and Type. The variables can be viewed at run time and modified directly in the variables window. The changed values are highlighted in red and this is a useful way to test applications with values that stress the program. Here, first we insert a breakpoint over the Addition method and start Debugging by using F5 when we perform Step Over F10 and then open the Watch window from the Debug menu.
Then, we manually writevar1 and var2 and hit enter. It will display the values that are assigned at run time. The Locals window lists the local variables that are currently in scope.
The only difference between the watch and locals window is that the locals window displays all the values of the variable that are currently in scope. It shows functions that are presently on the stack.
The current location is highlighted with a yellow arrow. Here,the call stack window displays the current executing function which is in stack:. The Immediate window is a command line version of the Visual Studio debugger. You can display a value in the window, evaluate expressions, execute applications and perform menu commands. You should first start the application in debugging mode by using F5 and then open this window.
The QuickWatch window is great to the programmer for inspecting the values of variables at run time. Here, we can reevaluate the current variable or manually enter different expressions, as can be seen on the image below:. The Thread window lists the active threads of the current process.
This window is available only in break mode. A new tab for your requested boot camp pricing will open in 5 seconds. If it doesn't open, click here. He earned a Master and Bachelor Degree in Computer Science, along with abundant premier professional certifications.

Diamond Signify a trace point that has continue option enabled Hollow Circle Signify a disabled breakpoints. Step Into F11 : If we want to go deep into any function body or instruction, then we can do this by hittingF11 when the debugging cursor is over any particular function.
Thereafter, we can move forward by using F10 for checking next instruction. Step Over F10 : Steps to the next source line or instruction continuously; time to time we can check the value of a particular variable or object by mouse point hovering.
Commands Alias Debug. Breakpoints bl Debug. For more information about Source Link, see the Source link specification. Because Source Link will download files using http or https, make sure you trust the. Require source files to exactly match the original version : Tells the debugger to verify that a source file matches the version of the source code used to build the executable you are debugging. When the version does not match, you're prompted to find a matching source.
If a matching source is not found, the source code will not be displayed during debugging. Redirect all Output window text to the Immediate window : Sends all debugger messages that would ordinarily appear in the Output window to the Immediate window instead.
Show raw structure of objects in variables windows : Turns off all object structure view customizations. For more information about view customizations, see Create custom views of managed objects.
Disabling optimization may make it easier to debug some problems, although at the expense of performance. For more information, see JIT optimization and debugging.
NET apps. On first use in Chrome, you may need to sign into the browser to enable Chrome extensions that you have installed. Disable this option to revert to legacy behavior. Enable using the multi-target JavaScript debugger for debugging JavaScript in applicable targets requires debugging restart Enables connection to the browser and back-end simultaneously, allowing you to debug your code running in the client and server right from the editor.
Load dll exports Native only : Loads dll export tables. Symbol information from dll export tables can be useful if you are working with Windows messages, Windows procedures WindowProcs , COM objects, or marshaling, or any dll for which you do not have symbols. Reading dll export information involves some overhead. Therefore, this capability is turned off by default. Symbols are available for any bit system dll.
This is useful for setting a breakpoint on a function. Function names from dll export tables might appear truncated elsewhere in the debugger. The calls are listed in the calling order, with the current function the most deeply nested at the top.
Show parallel stacks diagram bottom-up : Controls the direction in which stacks are displayed in the Parallel Stacks window. Ignore GPU memory access exceptions if the data written didn't change the value : Ignores race conditions that were detected during debugging if the data didn't change. Use Managed Compatibility Mode : Replaces the default debugging engine with a legacy version to enable these scenarios:.
You are using a. Choosing Managed Compatibility mode disables some features that are implemented only in the default debugging engine. The legacy debugging engine was replaced in Visual Studio Warn when using custom debugger visualizers against potentially unsafe processes Managed only : Visual Studio warns you when you are using a custom debugger visualizer that is running code in the debugged process, because it could be running unsafe code.
Enable Windows debug heap allocator Native only : Enables the windows debug heap to improve heap diagnostics. Enabling this option will impact debugging performance. Show runtime tools in application : Shows the Live Visual Tree commands in a toolbar on the main window of the XAML application that is being debugged. This option was introduced in Visual Studio Update 2.
We will soon be bringing this change for native code as well. We really appreciate you taking the time to try our newest feature and we hope you will provide your honest feedback by taking this brief survey.
Share Your Feedback. Comments are closed. The list of external sources can get really long. For example: System -System. IO —System. As mentioned and in the blog, this is just the first stage and we really looking for customer feedback to make it more user-friendly and productive. I will add both of your suggestions to our backlog to explore them further.
We hacked the build process in Uno. UI to be able to debug a locally built version of our library. Pretty useful to test the impact of changes locally before pushing them to build server. The other thing is that sorting and filtering is must have with this kind of feature. Thanks a lot for trying the feature.
For the private NuGet you are having issues with; do you have the sources checked out locally for it by any chance? Feel free to reach us on vsdbgfb microsoft. I can confirm that External Sources are now working in preview4 for symbols integrated with source codes.
Until now I had to associate them as a reference just for debugging. But in debugging my main problem is remote debugging of applications installed on clients. Hope there are improvements as well because I can only debug while on the same network or domain. Why is this a debug only feature? It would be just as useful to have access to external sources while writing code.
Today I have to use ILSpy all the time. Thanks for the suggestion. That is something we might consider for our future improvements.
