Re: Memory Profiler hangs after upgrading to 5.7 version

I'm sorry for the delayed response, I didn't receive the notification about your reply. Since it hangs even when you disable DirectX and after you have removed the video-card, it seems like the issue is probably not caused by the charting component. We will do some more investigations related to thi...

Re: Memory Profiler hangs after upgrading to 5.7 version

It seems like the hang is somehow related to the real-time view, and most likely the third-party graph component we use. Can you try to disable Direct3D rendering in the real-time view and see if it works better? You can disable Direct 3D rendering on the Preferences page under Tools->Options. Desel...

Re: Memory Profiler hangs after upgrading to 5.7 version

This is not something we have heard about before, but since it works when you select the "very low" setting it may have something to do with the real-time plots. Can you try to just disable real-time data collection? You can do that by selecting the custom level and click next until you reach the re...

Re: How to run Profiler with MSTest.exe

1. The NmpCore command looks fine, but there’s a risk that the actual test process doesn’t get profiled. Adding the “/noisolation” flag may help with this, but a better option would be to specify that all processes should be profiled. You can specify that all processes should be profiled by using th...

Re: How to run Profiler with MSTest.exe

How do you start “mstest.exe”? In order to profile unit tests, the test runner needs to be started by .NET Memory Profiler. It’s not enough to add “SciTech.MemProfilerApi” to the project. There are several ways to run tests under the profiler, e.g. using the standalone profiler, NmpCore, or the Visu...

Re: Console application Main function has a reference which prevent object to be GCed

Your Main method contains global event handler registrations, anonymous functions, LINQ queries, and is an async method itself (with an accompanying state machine). A lot of data will be stored in local variables and it's hard to determine the lifetime of each variable. I don't think the runtime mak...

Re: Error using NmpCore MSBuild Task

As you noticed, there's an error in the SciTech.NmpCore.Task.targets file included with with the SciTech.NmpCore.Task package (v5.7.21). It refers to the wrong directory for the NmpCore.exe file. We have now corrected this error and uploaded an updated package, v5.7.23. Can you upgrade to this versi...

Re: Console application Main function has a reference which prevent object to be GCed

I'm sorry for the late reply. It's hard to identify why an instance has not been GCed based on your description and the screenshot. To better help you with this I would need some more information. Is the FdcServerHostApp instance (#34,706), the instance you believe should be GCed? It's being kept al...

Re: Memory Profiling in a CI workflow - Virtual Machines

Hi, The internal .NET Memory Profiler API, the NmpCore task, and the NmpDataCollector are available as NuGet packages (SciTech.MemProfilerApi, SciTech.NmpCore.Task, SciTech.NmpDataCollector), but then snapshots can only be collected from within the profiled process. The external API, that allows you...

Re: NmpCore dotnet core Linux

Yes, we plan to add support for .NET Core applications running on Linux. In version 6.0, both .NET Memory Profiler and NmpCore will be running as .NET Core applications (or more likely .NET 5 applications). The profiler itself uses WPF so it will be be Windows only, but NmpCore will be cross platfor...

Re: List of garbage collected instances

I think we are meaning the same thing. I was also talking about getting a list of instances that existed in snapshot #1 and no longer exist in snapshot #2. The "Removed instances" value does represent the number of these instances. However, if you look at the type details, you will not get a list wi...

Re: List of garbage collected instances

It is currently not possible to get a list of garbage collected instances, but we're actually working on a feature that will make this possible. It's a four-way compare of snapshots, from up to two different sessions. With this comparison, full instance information will be available for two differen...

Re: Newbe: Is this a leak

The instance graph shows that you have an XmlDocument that is kept alive through the X_Doc field of a Lokal_bon instance. As long as you intend to use the data in the XmlDocument again this is not a memory leak. And since the Local_bon instance is referenced be a method (Send_the_rest) it seems like...

The current version of .NET Memory Profiler does not provide timing information for garbage collections.
