TableValuedParameter not working

[bsagal]

When running a query with a parameter object containing TVP field an exception is thrown. The same code without the [DapperAot] attribute workes as expected.

Code to reproduce:

using System.Data.Common;
using Dapper;
using Microsoft.Data.SqlClient;
using Microsoft.Data.SqlClient.Server;

var db = new SqlConnection(args[0]);

await db.BulkInsert(Enumerable.Empty<SqlDataRecord>());

public static class Utils {
    
    [DapperAot]
    public static Task BulkInsert(this DbConnection connection, IEnumerable<SqlDataRecord> values)
        => connection.ExecuteAsync("INSERT INTO table SELECT * FROM @values",
                                   new { values = values.AsTableValuedParameter("dbo.ValuesType") });
}

Received exception:

System.ArgumentException: No mapping exists from object type Dapper.SqlDataRecordListTVPParameter`1[[Microsoft.Data.SqlClient.Server.SqlDataRecord, Microsoft.Data.SqlClient, Version=5.0.0.0, Culture=neutral, PublicKeyToken=23ec7fc2d6eaa4a5]] to a known managed provider native type.

Thanks. We need some additional work for this, which is already in progress but incomplete; so - yes, thanks for report - it helps prioritization; will get this landed ASAP
