After installing Articulate on a new project, when I tried to load the 'Settings' section within the Umbraco back-end I start getting this error:
System.NullReferenceException: Object reference not set to an instance of an object.
--- End of stack trace from previous location where exception was thrown ---
After a lot of head scratching, uninstalling plug-ins and e=installing I was able to figure out the issue was a dependency injection issue. Within my project, I was using Autofaq and the Articulate assembly needs to be registered within the DI set-up code, otherwise, it errors.
To register articulate with Autofaq within your DI set-up, you will need to add some code similar to the snippet below:
var assembliesToRegister = new
var builder = new ContainerBuilder();
builder.Register(c => UmbracoContext.Current).AsSelf();
foreach (var assembly in assemblies)
After registering Articulate with the RegisterApiControllers, when you rebuild your solution, the error should go away.
