System.Diagnostics.StackFrame performance degrade in Windows 10

Download PC Repair Tool to quickly detect & fix Windows errors automatically

If later you upgrade to Windows 10 or .NET Framework 4.7.1, and y'all notice a significant subtract in performance when you run .NET Framework applications that use the Organisation.Diagnostics.StackFrame class, then this post might involvement you. We will look at the crusade, and and then offer known fixes for the error.

Organization.Diagnostics.StackFrame performance dethrone

An application that had acceptable performance running on the .Cyberspace Framework 4.7 or before versions executes more than slowly when running on the .Cyberspace Framework iv.vii.one. Applications typically rely on StackFrame when they throw .Internet exceptions. If this occurs at a high rate (more than 10 incidents per 2d), applications tin can slow down significantly (tenfold) and run noticeably slower than before.

Cause of the Organization.Diagnostics.StackFrame performance dethrone

The .Cyberspace Framework 4.7.i in Windows x added back up for detecting and parsing the Portable PDB file format to show file and line number information in stack traces. Equally part of this change, each role in a stack trace has its defining module checked to make up one's mind if that module uses the Portable PDB format. Due to some differences in the internal caching policy, the runtime spends far more than fourth dimension searching for Portable PDBs than previous .Net Framework versions spent searching for classic Windows PDBs.

This causes formatted stack traces to be produced more slowly than before.

This issue does not change the number of exceptions that are thrown. Even so, it does significantly decrease the ability of applications to handle those exceptions.

Applications that utilize IKVM library are known to be affected by this result if they probe for assemblies. Probing for assemblies is known to cause exceptions.

Set Arrangement.Diagnostics.StackFrame performance degrade issue

To resolve this result, Microsoft recommends using either of the following methods.

1] Employ a dissimilar constructor for StackFrame that takes a Boolean statement

This is the preferred solution.

If application developers are able to make changes to their applications, call the System.Diagnostics.StackTrace.#ctor(Boolean) constructor by using a false statement to avoid capturing source data. This avoids the section of the code in which operation is decreased.

two] Rollback or upgrade to the latest Windows x version

In this method, roll back to the previous version/build or upgrade to the latest version/build of Windows 10 if you lot're experiencing this effect and you're not currently running the latest version of Windows x. Likewise uninstall .Net Framework 4.7.1 if nowadays, from your estimator then download and install a previous version or the latest version of .NET Framework.
