How to enable assembly bind failure logging (Fusion) in .NET

Question

How do I enable assembly bind failure logging (Fusion) in .NET?

Answer 1

Instead of using a ugly log file, you can also activate Fusion log via ETW/xperf by turning on the DotnetRuntime Private provider (Microsoft-Windows-DotNETRuntimePrivate) with GUID 763FD754-7086-4DFE-95EB-C01A46FAF4CA and the FusionKeyword keyword (0x4) on.

@echo off
echo Press a key when ready to start...
pause
echo .
echo ...Capturing...
echo .

"C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\xperf.exe" -on PROC_THREAD+LOADER+PROFILE -stackwalk Profile -buffersize 1024 -MaxFile 2048 -FileMode Circular -f Kernel.etl
"C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\xperf.exe" -start ClrSession -on Microsoft-Windows-DotNETRuntime:0x8118:0x5:'stack'+763FD754-7086-4DFE-95EB-C01A46FAF4CA:0x4:0x5 -f clr.etl -buffersize 1024

echo Press a key when you want to stop...
pause
pause
echo .
echo ...Stopping...
echo .

"C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\xperf.exe" -start ClrRundownSession -on Microsoft-Windows-DotNETRuntime:0x8118:0x5:'stack'+Microsoft-Windows-DotNETRuntimeRundown:0x118:0x5:'stack' -f clr_DCend.etl -buffersize 1024 

timeout /t 15

set XPERF_CreateNGenPdbs=1

"C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\xperf.exe" -stop ClrSession ClrRundownSession 
"C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\xperf.exe" -stop
"C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\xperf.exe" -merge kernel.etl clr.etl clr_DCend.etl Result.etl -compress
del kernel.etl
del clr.etl
del clr_DCend.etl

When you now open the ETL file in PerfView and look under the Events table, you can find the Fusion data:
