Hi everyone, I spent lot of time trying to integrate Umbraco in Visual Studio. I think I solved most of the problems, but when I launch the debug I still get a Server Error:

Object reference not set to an instance of an object. 
  Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

 Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Source Error: 


 An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.  

Stack Trace: 



[NullReferenceException: Object reference not set to an instance of an object.]
   Umbraco.Web.UmbracoModule.BeginRequest(HttpContextBase httpContext) +34
   Umbraco.Web.UmbracoModule.<Init>b__8(Object sender, EventArgs e) +191
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +141
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +69

I cleaned the cache and cookies on IE already, and I am working on VS2015. Thank you everyone for the help!
