Running VS and SharePoint on the same server, but I am unable to debug my simple Event Receiver to see why it is not firing.

Here is the snipp:

public class EventReceiver1 : SPListEventReceiver
    /// <summary>
    /// A list was added.
    /// </summary>
    public override void ListAdded(SPListEventProperties properties)

        TestReceiver(properties.WebUrl, properties.ListId);

    protected TestReceiver(string webUrl, Guid listGuid)
        using(SPSite site = new SPSite(webUrl))
            using(SPWeb web = site.OpenWeb())
                SPList list = web.Lists[listGuid];
                list.Description = "Test";

Solution deploys successfully, but going back to the UI and adding a list, description is not updated as seen in the TestReceiver() method. Attempting to attach VS to all w3wp process does not load any breakpoints either. What gives?


I have also confirmed via Powershell, that the document library does have my Event Receiver attached to it.

  • are you using sp2010 w/ .NET 3.5? – Michael Colbs Oct 16 '15 at 21:34
  • @Colbs SP2013 w/ .NET 4.5 – KidBatman Oct 16 '15 at 21:36
  • Have you ever gotten it to break? Like on the first deploy maybe? – Michael Colbs Oct 16 '15 at 21:41
  • @Colbs no not once to my recollection. To be honest, I don't even think the ER is firing. I added a try-catch to reach out and log to a DB, but nothing has been logged and the description of the list is never updated. – KidBatman Oct 16 '15 at 21:45
  • hmm, worked for me using ListAdding. Can you update the description in that event? – Michael Colbs Oct 16 '15 at 21:55

Re-deploying event receivers will sometimes continue to point to an old version. You may have tried some of these but here's how I would troubleshoot:

  1. Download SP Manager and drill down to the List where the Event Receiver is attached. You can remove / delete it manually.
    • use Powershell to remove the Event Rece3vier
    • Make sure you are attaching all W3WP Processes (From all Users)
    • Manually deploy the .dll to the GAC
    • Do a Full Retract / Install w/ Powershell (not VS)
    • IIS Reset
    • If all that fails, create a new list and new Event Receiver
  • A couple questions. Manually deploy the .dll... are you talking about physically dropping the .dll into the GAC or the old school stsadm way? Do a full Retract/Install... Are the Deploy/Retract options given through VS not sufficient for development of ERs? – KidBatman Oct 16 '15 at 21:59
  • You may have to use GACUtil.exe or manually navigate to GAC_MSIL to delete it. On rare occasions, Powershell will deploy things that VS cannot – Michael Colbs Oct 19 '15 at 17:15
  • I had tried all still Its not working – Akshay Dattatray Nangare Aug 31 '16 at 11:34


protected void TestReceiver(string webUrl, Guid listGuid)

instead of

protected TestReceiver(string webUrl, Guid listGuid)
