Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WAS
COR_ENABLE_PROFILING=1
COR_PROFILER={324F817A-7420-4E6D-B3C1-143FBED6D855}
COR_PROFILER_PATH_64=C:\Program Files\Microsoft CLR Instrumentation Engine\Proxy\v1\InstrumentationEngine.ProfilerProxy_x64.dll

- Process eventually crashes with the following information:
| Module | AspNetInitClrHostFailureModule |
|---|---|
| Notification | BeginRequest |
| Handler | ExtensionlessUrlHandler-Integrated-4.0 |
| ErrorCode | 0x80131534 (COR_E_TYPEINITIALIZATION) |

Research direction
Start by reproducing the crash using the listed DynaTrace registry settings, IIS, localhost, and a debugger attached to w3wp.exe. Investigate the reported AspNetInitClrHostFailureModule and COR_E_TYPEINITIALIZATION failure; no source file or test is identified in the issue. Done means the same request no longer causes the worker process to crash.
