dotMemory is a .NET memory profiler by JetBrains. My name is Ilya and I help develop the tool. I'd like to tell you a classical dogfooding story of how we optimized one of dotMemory's algorithms by using our own tools – dotMemory and dotTrace. We then improved it some more using dotTrace, and finished off the optimization process by using BenchmarkDotNet. I’d like to thank the authors of two articles, 1 and 2, which inspired me to share this story. It all began when a colleague messaged me in Slack about a problem he was experiencing with the dominator tree in dotMemory. The data

We’ve just released the 2022.1 versions of dotTrace, dotMemory, dotCover, and dotPeek. Take a look at what you can expect.  dotTrace 2022.1 The dotTrace command-line tool and dotTrace in Rider now support Alpine versions 3.13–3.15.You can now open NetTrace files collected with dotnet-trace collect. dotTrace supports SQL Server events from the Microsoft.Data.SqlClient provider.You can now use your keyboard to navigate the dotTrace Home window.

CLI is quite possibly one of the best things to have happened to the world of computing. Using a ubiquitous interface that lends itself extremely well for automation, we can create executables that allow us to share code across all operating systems a

In this post, we’d like to share our plans for ReSharper 2021.3 and find out what we can do next to improve your development experience. Your feedback is always welcome! The following is a list of our priorities for the 2021.3 release cycle. Note that these are features we’re working on – as opposed to features scheduled for delivery – and that some of these might be delayed until a later version. Visual Studio 2022 – We are excited to start preparing ReSharper for the upcoming major release of Visual Studio! We already have an early build of ReSharper for the preview edition and would lov

Together with ReSharper, we release a number of command line tools. Starting with the upcoming 2021.3 release, the dupFinder Command-Line Tool will no longer be included. The current 2021.2 version is the last release to include this tool. The ReSharper command line tools are a set of free, cross-platform tools that let you run specific ReSharper functionality from the command line, or as part of your Continuous Integration (CI) process. You can use the CleanupCode and InspectCode tools to clean up code and run code inspections using ReSharper (or Rider) settings.  In 2013, dupFinde

Great news, everyone!  ReSharper 2021.2 is now out! Before diving into the feature set, there is an important note. Starting with the 2021.2 release of our .NET productivity tools, including ReSharper, we will require .NET Framework 4.7.2 or newer to be installed on your machine. Learn more here. Now let’s have a look at what's inside.  Code Analysis The new Swap via deconstruction quick-fix is available to swap variable values! Nullable Reference Types ReSharper indicates suppressions (!) that are no longer needed and that can be safely removed.

dotMemory 2019.2 no longer supports remote profiling. Remote profiling allowed you to profile an application running on a remote computer with dotMemory running locally. So, why did we get rid of it? (more…)
