How to run Sql Scripts using MigrationBuilder up

I m trying to run sql scripts using 

public partial class RunMySqlScripts : Migration
    {
        protected override void Up(MigrationBuilder migrationBuilder)
        {

            //var sqlFilesFolder = Path.Combine(AppDomain.CurrentDomain.BaseDirectory.Substring‌​(0, AppDomain.CurrentDomain.BaseDirectory.IndexOf("bin")), "SqlScriptsUp");
            var sqlFile = Path.Combine(AppContext.BaseDirectory, "SqlScriptsUp"); migrationBuilder.Sql(File.ReadAllText(sqlFile));
        }

I keep getting this error when i run 

Update-Database

Access to the path 'D:\ARTSQLCORE\ARTSQLCORE\ARTNetCore\bin\Debug\netcoreapp2.0\SqlScriptsUp' is denied.

I m using ASP.NET Core 2
