How do I find a memory leak in Visual Studio?
The primary tools for detecting memory leaks are the C/C++ debugger and the C Run-time Library (CRT) debug heap functions. The #define statement maps a base version of the CRT heap functions to the corresponding debug version. If you leave out the #define statement, the memory leak dump will be less detailed.
How do you debug a memory leak?
When analyzing possible memory leaks, you need access to the app’s memory heap. Then you can analyze the memory contents. Looking at relationships between objects, you create theories on why memory isn’t being freed. A common diagnostics data source is a memory dump on Windows or the equivalent core dump on Linux.

How to debug a memory leak in.net core?
This tutorial demonstrates the tools to analyze a memory leak in a .NET Core app using the .NET diagnostics CLI tools. If you are on Windows, you may be able to use Visual Studio’s Memory Diagnostic tools to debug the memory leak. This tutorial uses a sample app, which is designed to intentionally leak memory. The sample is provided as an exercise.
How to analyze memory usage in Visual Studio?
The .NET Object Allocation tool helps you identify allocation patterns and anomalies in your .NET code. This tool runs only as a post-mortem tool. You can run this tool on local or remote machines. For detailed instructions that describe how to use the memory analysis tools, see the Analyze memory usage tutorial and the .NET Object Allocation tool.
Can a C + + developer use a non-debugger memory usage tool?
C++ developers can use either the debugger-integrated or non-debugger Memory Usage tool. You can use the profiling tools without the debugger with Windows 7 and later. Windows 8 and later is required to run profiling tools with the debugger ( Diagnostic Tools window).
