Smart Completion in lambda expressions not working

Hi! 

There is some extension method:

public static EntityEntries<TEntity> Entries<TEntity, TContext>(this TContext dbContext, Func<TContext, IEnumerable<TEntity>> entitiesFunc) 
 where TContext : DbContext
 where TEntity : class
 {
       return new EntityEntries<TEntity>(dbContext, entitiesFunc(dbContext));
 }

Now I'm trying smart completion:

Why no the suggest for lambda func?

I'm using VS 2017 + Resharper 2017

Thx
