If you switch to a new stack frame, you make that method the current method, and Method View shows all callers and callees for the new method. game aviamaster This may cause some threads to appear or disappear from the view, depending on whether that method appears on their call stacks. To return to the call stack view, select the Method View toolbar icon again. Debugging multithreaded applications can be complex, but Visual Studio is making it easier than ever. A new update enhances the debugging experience, helping developers gain clearer insights into their code’s behavior. Stay ahead with tools designed to simplify multithreaded development. From either Threads view or Tasks view, you can pivot the graph on the current method by selecting the Toggle Method View icon on the toolbar.
How do I Debug a multithreaded app?
This Visual Studio extension adds two shortcuts and toolbar buttons to allow developers to easily focus on single threads while debugging multi-threaded applications. This tab shows a list of the threads in the process and three columns of information. The following illustration shows one thread that goes from Main to a Managed to Native code transition. Two threads continue to Thread.Sleep, and two continue to Console.WriteLine and the current thread continues to SyncTextWriter.WriteLine. There is an alternative way of debugging the child process. After fork() is executed, put a sleep() call in the code where the child executes, get the PID of the child using the ps utility, then attach the PID . Now, you can debug the child process, like any other process. Parallel processing using many threads can greatly improve program performance, but it may also make debugging more difficult because you’re tracking many threads .
- There is an alternative way of debugging the child process.
- In Threads view, the stack frame and call path of the current thread are highlighted in blue.
- When the Threads view graph is too large to fit into the window, a Bird’s Eye View control appears in the window.

View threads and tasks in the Parallel Stacks window (C#, Visual Basic, C++)
Multithreading can introduce new types of potential bugs. Hover over a method to show aviamasters bgaming a tooltip with additional information. In Tasks view, the tooltip shows all the tasks in a table similar to the Tasks window. When the Threads view graph is too large to fit into the window, a Bird’s Eye View control appears in the window. You can move the frame in the control to navigate to different parts of the graph. The following shortcut menu items are available when you right-click a method in Threads view or Tasks view.
Positioning the Parallel Stacks window
- The top line is executed last and it is the current routine.
- Two threads continue to Thread.Sleep, and two continue to Console.WriteLine and the current thread continues to SyncTextWriter.WriteLine.
- Use the Generate Insights button to interact with Copilot about the thread data you’re seeing.
- This tab shows a list of the threads in the process and three columns of information.
- Now, you can debug the child process, like any other process.
- The following illustration shows how the same information looks in Threads view on the left and in Method View on the right.
Method View shows at a glance all methods on all threads that either call or are called by the current method. The following illustration shows how the same information looks in Threads view on the left and in Method View on the right. To change the current stack frame, double-click a different method. This might also switch the current thread, depending on whether the method you select is part of the current thread or another thread. The following illustration shows the Main thread in a Managed to Native code transition. Four threads continue executing in the S.C method context, while one worker thread continues in a Managed to Native code transition, setting the name on a worker thread. In Threads view, the stack frame and call path of the current thread are highlighted in blue. The current location of the thread is shown by the yellow arrow.
How do I know how many threads I have used?
The last six items are the same as in the Call Stack window. If you have Copilot, you can get AI assistance in the Threads view with AI-generated thread descriptions and by using the Generate Insights button. Use the Generate Insights button to interact with Copilot about the thread data you’re seeing. In this scenario, Copilot already knows the context for your question, so you don’t need to provide context yourself in chat. Call stack is set of lines, which is usually read from top to bottom – meaning moving from current locations to callers.
