Find() and FindAsync() techniques on typeDbSet (That is what)db.Items is). Include() provides aDbQuery hence; objectFindAsync() is not offered. UseSingleOrDefaultAsync() to act similarly toFindAsync() (The difference is that it won't first check the context to determine if the entity already exists; instead, it will proceed directly to the database.)
Jun 5, 2015 · The difference is in a syntax. Find and FindAsync both allows to build asynchronous query with the same performance, only.

May 5, 2015 · Any time that you need to do an action on a remote server, your program generates the request, sends it, then waits for a response. I will use SaveChanges() and SaveChangesAsync() as an example but the same applies to Find() and FindAsync(). Say you have a list myList of 100+ items that you need to add to your database. To insert that, your function would look something like so:
