title: How to pass variable into layout in .NET?
body: <p>My aplication have walls with notes. I wish to put on layout name of active wall. 
  How to do that?
  I know that on front-end I can use just @Model... but who sends this model? 
  Also better idea is store this information in session variable or create another property in user database?</p>
  
  <p>EDIT: I use .NET Core 1.1.</p>
