Sequential GUIDs

[caleblloyd]

• Adapt Sequential GUID generation to work on MySQL
• Re-work of initial PR MySQL 顺序Guid算法更新 #258
• Must take into consideration if GUIDs are stored as binary (OldGuids=true) or char(36) (OldGuids=false)

Still need to add tests before we can merge

Interesting.. What would I have to do to make advantage of this? We already use char(36) as column type for our GUIDs. Would this affect existing data?

Edit: I guess this is about https://docs.microsoft.com/en-us/ef/core/modeling/generated-properties?

This only affects GUIDs that are part of the primary key that have not been set. It will set them automatically, no data annotation needed.

This happens right now, except the generated GUID is optimized for SQL Server, and not MySQL.

@kagamine, nice to see that this one has been merged. May I ask for a new nuget beta build, would love to play with it?
