Overview

When attempting an upgrade of NPM, the following error appears in the Configuration Wizard:

Method not found: 'System.Data.Entity.ModelConfiguration.Configuration.PrimitivePropertyConfiguration
System.Data.Entity.ModelConfiguration.Configuration.PrimitivePropertyConfiguration.
HasDatabaseGeneratedOption(System.Nullable`1<System.ComponentModel.DataAnnotations.Schema.DatabaseGeneratedOption>)’

Environment

NPM version 12

 

Cause 

The cause of this is a number of files in the Orion Installation Directory didn't get correctly upgraded.

 

Resolution

  1. Open the installation directory (default C:\Program Files (x86)\Solarwinds\Orion).
  2. Remove the files EntityFramework.dll and EntityFramework.SqlServer.dll. Back them up to a location outside of Program Files.
  3. Run > appwiz.cpl.
  4. Select Solarwinds Orion Core Services 2016.1.
  5. Repair and run through the Configuration Wizard.
