Error_27_Error occurred in deployment step 'Activate Features': Operation is not valid due to the current state of the object. RRS feed

  • Question

  • I created a SharePoint 2013 farm solution project in Visual Studio 2013 (running on the same machine where SharePoint 2013 server is running) with event receiver.  I added web.config at project root level to store connection string (I'm working off external SQL DB) and got the following error during deployement:

    Error 27 Error occurred in deployment step 'Activate Features': Operation is not valid due to the current state of the object.

    When I commented out the ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString; the error went away.  Am I missing something or not supposed to add my own App.config to SharePoint project solution?
