Meta Data not found when using a Windows Service

[Nathan Kovac]

Yesterday afternoon I was getting the following errors in a windows service:

'DatabaseManage r.DataComponent ', 'Error', '3 Errors:
Line: 0 - Metadata file 'ScriptingMetho ds.dll' could not be found
Line: 0 - Metadata file 'RemoteLoader.d ll' could not be found
Line: 0 - Metadata file 'wwScripting.dl l' could not be found'

Service ran all night fine. This morning I reconnected to the process and
the errors are no longer there. Only thing I can think of is if logging off
and back on did something. I should also note that yesterday visual studio
crashed on me when I had the solution open and tried to connect to the
windows service project.

Does anyone with a better understanding of the CLR have any possible
explaination for the inconsistant errors?

Thanks,
Nathan

Nathan,

Are all of these your dlls? Are these exceptions that are being thrown
and logged? If so, what are the types of the exceptions, as well as the
other details?

Scripting Methods.dll I wrote from scratch.

RemoteLoader.dl l and wwScripting.dll are mostly code snippets from others
have done online.

In 'DatabaseManage r.DataComponent ' which is one I wrote I have the following
method. Notice the error handling. All I logged was e.Message. If you
think I should grab more information for next time please let me know. When
I was debugging with a windows form I was logging to a file. When I made it
a service I discovered I couldn't do that, and at the time I got these
errors I was simply having log dump to the Debug.WriteLine . I will have it
logging to Sql soon.

What's the identity of the service account?
Where are these dll's located?
What dependencies do they have?
What's are you using in AddAssembly to locate/load the DLL's?

Yesterday afternoon I was getting the following errors in a windows
service:

'DatabaseManage r.DataComponent ', 'Error', '3 Errors:
Line: 0 - Metadata file 'ScriptingMetho ds.dll' could not be found
Line: 0 - Metadata file 'RemoteLoader.d ll' could not be found
Line: 0 - Metadata file 'wwScripting.dl l' could not be found'

Service ran all night fine. This morning I reconnected to the process
and the errors are no longer there. Only thing I can think of is if
logging off and back on did something. I should also note that
yesterday visual studio crashed on me when I had the solution open and
tried to connect to the windows service project.

Does anyone with a better understanding of the CLR have any possible
explaination for the inconsistant errors?

Thanks,
Nathan
