ArgumentNullException: Value cannot be null. Parameter name: connectionString

So I posted it.

It happened to me twice this morning.

In my first thought, I said, "What?"

On my second attempt, I still got the same error.

And I said to myself, "What the f*?"

Then, finally I found that in my appSettings.json, I misspelled the ConnectionStrings to ConnectionString.

Now, I realize that too much coffee is not a replacement to lack of sleep and not an excuse for stupidity, lol!

Anyway, I'm just having fun working on my dotNet Core project 😁
