There are two ways to do this:. Tell your user that they must install a developer license on their Windows 8 machine before using your tool. This can be done automatically from Visual Studio or manually from a command prompt.
For more information, see Get a developer license. Generally, Windows Store apps are only allowed to access a limited set of locations on the disk. Each Windows Store app can access its own application data folders, as well as a few other areas in the file system for which all Windows Store apps are granted access.
It's best to install your Profiler DLL and its dependencies somewhere under Program Files or Program Files x86 , because all Windows Store apps have read and execute permissions there by default. The same holds true for Windows Store apps, but the mechanisms are different.
If Process A attempts to spawn Windows Store app Process B, Process A should be run at medium integrity level, not at high integrity level that is, not elevated. This means that either your Profiler UI should be running at medium integrity level, or it must spawn another desktop process at medium integrity level to take care of launching the Windows Store app. You can use the PackageManager class to generate this list.
PackageManager is a Windows Runtime class that is available to desktop apps, and in fact it is only available to desktop apps. The following code example from a hypothetical Profiler UI written as a desktop app in C uses the PackageManager to generate a list of Windows apps:. In order to pass the custom environment block to the Windows Store app, you need to write your own, simplistic dummy debugger.
Windows spawns the Windows Store app suspended and then attaches your debugger by launching your debugger with a command line like in this example:. Your dummy debugger would parse the ThreadID from the command-line, resume that thread, and then exit. The moment to launch the Windows Store app has finally arrived.
Yes, one package can have multiple applications, and each application has its own Application User Model ID. When you called IPackageDebugSettings::EnableDebugging , you made a promise that you would clean up after yourself by calling the IPackageDebugSettings::DisableDebugging method, so be sure to do that when the profiling session is over. The same holds true with Windows Store apps.
But in addition to the common considerations listed earlier, make sure the that the target Windows Store app is not suspended. Now your Profiler DLL must be taught how to play by the different rules required by Windows Store apps, including which APIs are allowable and how to run with reduced permissions.
For example, the Requirements section of the documentation for the InitializeCriticalSectionAndSpinCount function indicates that the function applies to desktop apps only. Such APIs are not guaranteed to work when called in the unique context that Windows Store apps run in.
Such APIs might seem to work fine from Windows Store apps in the current version of Windows, but may break or be disabled in future releases of Windows. You might find that you absolutely cannot do without a particular API and cannot find a replacement suitable for Windows Store apps. In such a case, at a minimum:. Understand that the API might suddenly break or disappear if called from inside Windows Store apps in future releases of Windows. N95, KN95, KF94 masks. GameStop PS5 in-store restock.

NET Framework. There are plenty of commercial profiler tools available, but Microsoft provides a free one called the CLR Profiler. The download is comprised of a single installation program that places the tool on your system.
In addition, extensive documentation is included. The CLR Profiler allows you to take a peek under the hood of a. NET application and see what is happening as it runs.
It also lets you monitor what is happening with the garbage collector heap. By installing the CLR Profiler, you can access the following information about an application:. The data used by the CLR Profiler is stored in self-contained log files.
The application provides both Windows client and command-line interfaces. In addition, the size of the log data files can become overwhelming depending on what is being logged, so be wary of disk space. Finally, the CLR Profiler starts the application it will be profiling, so you cannot attach it to currently running processes. Running the application is easy via the Windows client interface. The simple interface allows you to start and stop profiling, as well as view the current contents of the heap.
In addition, you can start and stop profiling a good option if you're only profiling during certain operations via a checkbox. A log file is created once profiling has been stopped. Profiling a Windows Service is like profiling a common language runtime application. Both profiling operations are enabled through environment variables.
Because a Windows Service is started when the operating system starts, the environment variables discussed previously in this topic must already be present and set to the required values before the system starts. In addition, the profiling DLL must already be registered on the system. Note that these changes will enable profiling on a system-wide basis.
To prevent every managed application that subsequently runs from being profiled, you should delete the system environment variables after you restart the target computer.
This technique also leads to every CLR process getting profiled. The profiler should add logic to its ICorProfilerCallback::Initialize callback to detect whether the current process is of interest. If it is not, the profiler can fail the callback without performing the initialization. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info.
