This library adds basic support for "Upsert" operations to EF Core.

Uses `INSERT … ON CONFLICT DO UPDATE` in PostgreSQL/Sqlite, `MERGE` in SqlServer and `INSERT INTO … ON DUPLICATE KEY UPDATE` in MySQL.

Also supports injecting sql command runners to add support for other providers

A typical upsert command could look something like this:

```csharp

DataContext.DailyVisits

    .Upsert(new DailyVisit

    {

        UserID = userID,

        Date = DateTime.UtcNow.Date,

        Visits = 1,

    })

    .On(v => new { v.UserID, v.Date })

    .WhenMatched(v => new DailyVisit

    {

        Visits = v.Visits + 1,

    })

    .RunAsync();

```

In this case, the upsert command will ensure that a new `DailyVisit` will be added to the database. If a visit with the same `UserID` and `Date` already exists, it will be updated by incrementing it's `Visits` value by 1.
