Event Receiver error

Question

Hi,

I used the following powershell to deploy an event receiver which targets a particular list, however, I am receiving the following error message when I try to fire the event receiver. Also, when I check the PublicKeytoken on the actual dll in the GAC, the number is different from below. Can anyone tell me how to fix this issue?

----------------------------------------------------------Error ---------------------------------------------------------------------------

Event manager error: Could not load file or assembly 'ContractHubEventReceiver, Version=1.0.0.0, Culture=neutral, PublicKeyToken=6263e36ca7fde497' or one of its dependencies. The system cannot find the file specified.

------------------------------------------------------Powershell--------------------------------------------------------------------------

Add-SPSolution -LiteralPath C:\webparts\ContractHubEventReceiver.wsp

Install-SPSolution -Identity ContractHubEventReceiver.wsp -GACDeployment -CompatibilityLevel 15

thanks,

Sherazad

Hi,

Please check the following threads with similar issue.

http://sharepoint.stackexchange.com/questions/45219/error-loading-and-running-event-receiver-could-not-load-file-or-assembly-custom

https://blogs.msdn.microsoft.com/sharepoint_bar__grill/2011/04/09/delete-orphaned-event-handler-through-powershell/

Or try to use the following PowerShell to delete the event receiver, then redeploy it.

$var = Get-SPSite -limit All | Get-SPWeb -limit all | % {$_.EventReceivers} | where {$_.Assembly -like "*ContractHubEventReceiver*"} | Select Assembly
$var | % {$_.Delete()}

Best Regards,

Hi,

You might have created the new solution and copied the code from existing event receiver to your new one and tried deployment.

In this case, feature id shares the same with two solution and subsequently orphaned on continuous deployment. Retract the earlier solution from the farm and ensure its the assembly file got removed from the GAC and the use the powershell command given by Dennis .

Now you can rectify this, change the feature id on your new solution and deploy.
