We want to use latest SDK and ability to run against net6.0 tests. It looks like the pool issue with VS 2022 has been resolved on the AppVeyor side so: yay! That solves everything cleanly with no installs.
Simplifying and improve build speed.
- Decreases builds from 8-13 minutes down to ~2 minutes (while running more tests)
- Moves to SQL Server 2019 on AppVeyor
- Moves the 2 longest running tests with params to `[FactLongRunning]`
- Bumps tests up to `netcoreapp3.1`
- Also fixes .Contrib tests
- Moves to `Build.csproj`
- Simplifies `build.ps1`
- Removed defunct `build.sh`
- Nukes `IsAppveyor` (moves to environmental variable overloads)
- Builds now work in Linux/macOS
This is a branch cleaning up old `#if` clauses, `.csproj` bits, Linux build compatibility, and a few other tid-bits (broken out by commit).
In general: we're on 3.0 tooling and all previous cruft has been removed.
Adding a dapper specific feed, for much easier pushing to NuGet. When
they implement Ctrl+Click in the UI this won't be necessary...or we
break down and automate it finally. Depends on signing plans later.
