MariaDb ConfigureServices.AddDbContext() broken in alpha-2

[seagull22]

Steps to reproduce

Add this statement to your ConfigureServices() method in Startup.cs:

services.AddDbContext<myDbContext>(opts => 
{
    var connStr = "your-value-here";
    var version = new ServerVersion(new Version(10, 5, 5), ServerType.MariaDb);
    opts.UseMySql(connStr, mySqlOptions => mySqlOptions.ServerVersion(version));
});

The issue

The above code compiles and runs well in alpha-1, but in apha-2 it won't compile.

compiler error message:
Startup.cs(49,31): error CS0144: Cannot create an instance of the abstract type or interface 'ServerVersion' 
[Server.csproj]
Startup.cs(50,69): error CS1061: 'MySqlDbContextOptionsBuilder' does not contain a definition for 'ServerVersion' and no accessible extension method 'ServerVersion' accepting a first argument of type 'MySqlDbContextOptionsBuilder' could be found (are you missing a using directive or an assembly reference?) [Server.csproj]

See this breaking change: #1233
Further discussion can also be found at #1088 (comment) and the following posts.

Both references contain all the common ways to set the new mandatory serverVersion parameter.

In short, for your specific case, using MariaDbServerVersion instead of ServerVersion would be a viable option.

Thanks, I got it working. I didn't see the breaking changes earlier, or I would not have troubled you.

@seagull22 No worries. We are thinking about making the options to choose from easier discoverable.
