Runtime Error while connecting HANA DB from VS Code


Dear Folks,

I am trying to connect SAP HANA instance from VS Code using .net 7.0.

I have installed .net7 SDK and SP

I am getting below error while creating HanaConnection object.

Exception has occurred: CLR/System.TypeInitializationException
An exception of type 'System.TypeInitializationException' occurred in Sap.Data.Hana.Core.v2.1.dll but was not handled in user code: 'The type initializer for 'Sap.Data.Hana.HanaConnection' threw an exception.'
Inner exceptions found, see $exception in variables window for more details.
Innermost exception System.IO.FileNotFoundException : Cannot find a matching libadonetHDB.dll with version 2.11.14 - check the location in the HDBDOTNETCORE or PATH / LD_LIBRARY_PATH / DYLD_LIBRARY_PATH environment variables

You may refer below code for reference.

using TestCode.Models;
using Sap.Data.Hana;
namespace TestCode.Controllers;
public class HomeController : Controlle{
private readonly ILogger<HomeController> _logger;
public HomeController(ILogger<HomeController> logger){
_logger = logger;
HanaConnection conn = new HanaConnection();
conn.ConnectionString = "connectionstring";
public IActionResult Index()
return View();
public IActionResult Privacy()
return View();
[ResponseCache(Duration = 0, Location = ResponseCacheLocation.None, NoStore = true)]
public IActionResult Error()
return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier });
