I am trying to track what causes my application to crash on start when launched from production. When launched from debug in Visual Studio, this C#/.NET windows application starts without any problem, and results are as expected. Previous versions of the same application have also been deployed and ran on other client computers.
Reading from the explanation found in Windows Error Reporting and CLR integration, it seems my problems comes from a method in assembly ExcelInterop.
Error Bucket , type 0 Event Name : CLR20r3 Answer : Non available CAB ID : 0 Problem signature : P1 : afiv2.exe ' my application P2 : 0.19.4826.21736 P3 : 51489aa0 P4 : ExcelInterop ' my library P5 : 1.0.0.0 P6 : 514878d9 P7 : 13 ' MethodDescr ??? P8 : 56 P9 : PSZQOADHX1U5ZAHBHOHGHLDGIY4QIXHX P10 :
Trying to locate the error I launched the application using windbg.exe menu-->File-->Open Executable (first time I use windbg), but console showed that Symbol search path was invalid. As per Debugging .net using SOS, I recovered symbol path using the following command sequence:
!sym noisy .symfix .reload -f
First trial loading SOS lead to an "Unable to find module mscorwks" error, Help:Failed to load sos in windbg solved this part of the problem:
sxe ld:mscorlib g .loadby sos mscorwks !token2ee ExcelInterop 06000013
I expected that the last command would determine the methodDesc associated with the number in the event report, but nothing was returned.
I now feel trapped in a kind of maze. What else should be done to find what is causing the crash on start?
