System.Net.Http.HttpClient' does not contain a definition for 'PostAsJsonAsync

Error: 'System.Net.Http.HttpClient' does not contain a definition for 'PostAsJsonAsync' and no extension method 'PostAsJsonAsync' accepting a first argument of type 'System.Net.Http.HttpClient' could be found

Solution: 
You need to add a reference to
System.Net.Http.Formatting.dll
This can be found in the extensions assemblies area.
A good way of achieving this is by adding the NuGet package System.Net.Http.Formatting.Extension to your project.

Ok, this exception "A collection with cascade="all-delete-orphan" was no longer referenced by the owning entity instance" can happen with NHibernate if you have an entity with a list of other entities with the .Cascade.AllDeleteOrphan() mapping. If you clear the list by assigning it a new List<entity>(), this exception will appear. Instead clear the list by using the .Clear() method.
