* Fix warnings, improve performance
`QueryResult.Items` is now a `IReadOnlyList` so we don't need to
allocate a new `Array` when we have a `List` (and `Items` shouldn't need to
be mutable anyway)
* Update Providers .csproj to latest C#
* Remove extra newline from DtoService.cs
* Remove extra newline from UserLibraryService.cs
* Remove some unused variables
* remove duplicate "using .." by sorting and deduping the list
* Remove things that already exist in the parent class (in one case I moved some documentation to the parent)
* EntityBodyData and and NextSearch were never set (only read), removed
* _timeout was never read, subsequently _timer became unused. part of a TODO timeout functionality that was not implemented yet
Add Argument*Exceptions now use proper nameof operators.
Added exception messages to quite a few Argument*Exceptions.
Fixed rethorwing to be proper syntax.
Added a ton of null checkes. (This is only a start, there are about 500 places that need proper null handling)
Added some TODOs to log certain exceptions.
Fix sln again.
Fixed all AssemblyInfo's and added proper copyright (where I could find them)
We live in *current year*.
Fixed the use of braces.
Fixed a ton of properties, and made a fair amount of functions static that should be and can be static.
Made more Methods that should be static static.
You can now use static to find bad functions!
Removed unused variable. And added one more proper XML comment.
