The dotTrace command-line tool and dotTrace in Rider now support Alpine versions 3.13–3.15. The following CPUs and frameworks are supported:
You can now open NetTrace files collected with
from the dotTrace Home menu, click Open Snapshot and choose a
Now dotTrace supports SQL Server events from the
Microsoft.Data.SqlClient provider on Windows (.NET Core, .NET 5+),
as well as macOS and Linux (.NET Core 3.0+, .NET 5+).
You can now navigate the dotTrace Home window using only keyboard combinations. No mouse is needed. Each UI element is assigned to a key or key sequence. There are two ways to view the assigned keys and interact with UI elements:
You can choose which to use in dotTrace Home | Settings.
You can now attach the profiler to an already running application by simply dragging the special icon onto the application window.
The dotTrace command-line tool now works on computers with Apple silicon processors. You can use it to profile .NET 6 applications (native mode) and .NET 5 applications (Rosetta 2 mode).
When you close a Timeline snapshot, dotTrace saves the state of the user interface, including selected time intervals, applied filters, and so on. Next time you open the snapshot, dotTrace will restore the UI to the same state.
The dotTrace command-line tool and dotTrace in Rider now let you collect data on asynchronous calls on macOS and Linux. To get this data, use the Timeline profiling mode. The Call Tree shows async calls, including awaits and continuations.
The dotTrace command-line tool and dotTrace in Rider can now profile child processes of applications on macOS and Linux in the Timeline profiling mode. This support is available only for .NET 5+ applications.
It’s now possible to profile native applications on Windows. When starting a profiling session, you have the option to download native source symbol files from remote servers. Native profiling is only available for the Timeline profiling type.
You can now profile .NET Core and .NET applications on macOS and Linux using the Timeline profiling type.
We’ve completely reworked the dotTrace Home screen. It’s much easier to configure and start new profiling sessions, work with snapshots, and perform other basic operations.
You can install and use the dotTrace command-line profiler as a
dotnet global tool:
dotnet tool install --global JetBrains.dotTrace.GlobalTools --version 2021.1.0
