hi,

i have a sharepoint visual webpart project to which i added a dll referece (weather.dll) for using the methods, and my intranet site has 2 languages, but the thing is the webpart is working only in english site so i tried to debug the Sharepoint project and i was not able to debug the methods which i am using from the weather.dll

i am getting the exception error ( object reference not set to an instance of the object )

so is there any way to debug the dll reference which i added to the project.

Thanks

Check first the third party documentation and make sure that you call the APIs in the right manner.

you can user decompilers to decompile the code you can try something like .NET reflector 

check the logs and stack trace to make sure that the thirdparty is the source of your exception

My advise to use open source third-parties or online service 

hi,

actually there are 2 projects in the solution one is sharepoint project and other is class library project , and i have added the class library dll reference to the Sharepoint project but when i am trying to debug it , it  is only debugging the Sharepoint project.

i want to debug the class library project also.

Thanks

instead of adding the project dll as reference add the project itself as a reference
