LINQ Single vs First
...ustomer = db.Customers.Where( c=> c.ID == 5 ).First();
This code above introduces a possible logic error ( difficult to trace ). It will return more than one record ( assuming you have the customer record in multiple languages ) but it will always return only the first one... which may work some...
Is Task.Result the same as .GetAwaiter.GetResult()?
... while Task.Result will throw an AggregateException. However, what's the point of using either of those when it's async? The 100x better option is to use await.
Also, you're not meant to use GetResult(). It's meant to be for compiler use only, not for you. But if you don't want the annoying Aggrega...

How do I sort a dictionary by value?
..., simplified here as:
from collections import defaultdict
d = defaultdict(int)
for w in text.split():
d[w] += 1
then you can get a list of the words, ordered by frequency of use with sorted(d, key=d.get) - the sort iterates over the dictionary keys, using the number of word occurrences as a s...
