What JetBrains dotMemory is
JetBrains dotMemory profiles memory in .NET applications to investigate leaks, memory use, garbage collection, and allocation patterns. It works with standalone .NET programs, ASP.NET web applications, and other .NET processes. You can run it as a standalone desktop application, inside JetBrains Rider or Visual Studio, or as a command-line profiler for continuous-integration builds and recurring routines. Analysis tools compare snapshots, show object relationships and retention, and examine allocation and garbage-collection traffic. Built-in inspections identify issues such as duplicate strings, sparse arrays, leaking event handlers, and WPF bindings. Visual Studio navigation can open a type declaration from an object set. dotMemory Unit is a free framework for .NET memory checks in unit tests. Standalone and command-line tools support Windows, macOS, and Linux, subject to platform and architecture limits. Process dump analysis is unavailable on macOS, and Linux imports only Linux-created dumps. A 30-day trial is available.
Who it suits
Developers working on C# or VB.NET applications who need memory profiling and leak investigation. It also suits teams automating profiling in continuous integration.
