ASP.NET core db2 connection issue

I am trying to connect IBM db2 server in VS 2017 in ASP.NET Core application but it is throwing error as

Unable to load DLL 'db2app64.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

My connection string is:

var mycon = "Server=10.64.0.30;Database=Gbgeorr;User Id=FORMSCAPE;Password=******";

DB2Connection db2 = new DB2Connection(mycon);   //error throwing here 

if (db2.IsOpen == false)
  db2.Open();
