.NET Memory Profiler 5.0 Preview 2
SciTech Software is pleased to announce the second preview of .NET Memory Profiler 5.0. The major new features of .NET Memory Profiler 5.0 are:
- New WPF based user interface
- Easily run unit tests under the profiler using the Visual Studio test runner
- Remote profiling
- Profile multiple processes within the same session
- Work with multiple sessions in the standalone profiler
- Improved real-time presentation
- Support for snapshots that are larger than 4 GB
.NET Memory Profiler 5.0 comes with a new edition, the Enterprise edition. Several of the new features will only be available in the Enterprise edition, such as the Visual Studio test runner, remote profiling and multiple process profiling.
Licensed users of .NET Memory Memory Profiler 4.6 Professional, with an active subscription, will have access to all Enterprise edition features in the preview. Once the full version of .NET Memory Profiler 5.0 is released, there will be a possibility to upgrade from the Standard and Professional editions to the Enterprise edition.
New WPF based user interface
The .NET Memory Profiler user interface has been converted to WPF, with a more modern look and an improved user experience.
Easily run unit tests under the profiler using the Visual Studio test runner
By using the "Run unit tests under profiler" command, you can now easily run your unit tests under the profiler. For more information, see the demo below.
Remote profiling allows you to use a development computer to profile a process running on a computer where you do not want to or cannot install the full profiler. The NmpCore tool is used on the remote computer to provide remote profiling access to the computer. The new command line argument "/remoteagent" (short form "/ra") is used to enable remote profiling. For instance by using the command:
By default the port 35650 is used for remote profiling. This can be overridden by using the argument "/remoteagentport" (short form /rap"). For example:
NmpCore /ra /rap:25000
The demo below shows how to start a remote profiling session.
You can use the link in the side-bar to download version 5.0 of NmpCore, which is required for remote profiling.
Profile multiple processes within the same session
In the Enterprise of .NET Memory Profiler, the profiler will by default profile all child processes that are created by the profiled process. This simplies profiling of processes that are started using a .NET implemented launcher process. It is possible to profile all startup projects in a Visual Studio solution, within the same profiling session.
Work with multiple sessions in the standalone profiler
It is now possible to work with more than one session in the standalone profiler as well. Each session is represented by a tabbed document similar to when running under Visual Studio.
Improved real-time presentation
The real-time view has been redesigned. Both graphical and numerical data is presented in the same view, and it is possible to use the time-selector to show numerical data at a specific time in an active session as well.
Support for snapshots that are larger than 4 GB
It is now possible to collect snapshots with instance data that is greater than 4 GB. This is only available when running the standalone profiler on a 64-bit OS. Due to overhead in the profiler, it is recommended that a machine with at least 32 GB of memory is used when collecting snapshots larger than 4 GB.
This is a preview, so there is missing functionality and there will most likely be bugs that can cause the profiler to crash.
.NET Memory Profiler 5.0 requires .NET Framework 4.0 or later to be installed. If using .NET Framework 4.0, .NET Framework update KB2468871 must also be installed.
NmpCore 5.0 requires .NET Framework 3.0 or later to be installed.
Some other things that are left to fix:
- A lot of UI-tweaking is still needed.
- Profiling of Azure project (compute emulator) from Visual Studio.
- Installer should install the required prerequisites, i.e. .NET Framework 4.5 or .NET Framework 4.0 with KB2468871.
