Does not work with OleDbConnection

Good morning everyone.

I figured out that Dapper.Contrib does not support OleDbConnection, that because, for example on the Get function of SqlMapperExtensions.cs do:

var type = typeof(T);

            if (!GetQueries.TryGetValue(type.TypeHandle, out string sql))
            {
                var key = GetSingleKey<T>(nameof(Get));
                var name = GetTableName(type);

                sql = $"select * from {name} where {key.Name} = @id";
                GetQueries[type.TypeHandle] = sql;
            }

            var dynParams = new DynamicParameters();
            dynParams.Add("@id", id);

the "@" notation is not supported on OleDb, for my example I need to operate bot SQL Server and MS Access DB and OleDBConnection is the only way to accomplished both connection

There is a plan to support OleDbConnection "?" notation?

Start in SqlMapperExtensions.cs at the Get function and trace how SQL and DynamicParameters are constructed. Examine how the @id parameter is handled for SQL Server and what must differ for OleDbConnection's ? notation. Done means the reported SQL Server and MS Access/OleDbConnection use cases are supported without regressing existing behavior.
