Trying 30 day trial. Get "Devart.Common.LicenseException: Feature is not supported."

[johanrex]

I have created a .NET Core console program with the below code:

Code: Select all

using System;
using Devart.Data.Oracle;
using System.Diagnostics;

namespace consoledevart
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Before");

            string connStr = "Data Source = oraclexe; User ID = testuser; Password = secret;";

            using (OracleConnection conn = new OracleConnection(connStr))
            {
                conn.Open();
                var cmd = conn.CreateCommand();
                cmd.CommandText = "select * from user_tables";

                var reader = cmd.ExecuteReader();

                reader.Read();
                string col = reader.GetString(0);

                Console.WriteLine("From view: " + col);
            }

            Console.WriteLine("After");
        }
    }
}

I have added a licenses.config file to the project and set the "Copy to Output Directory" to True. It has the following two lines:

Code: Select all

consoledevart.dll
consoledevart.exe

I have added a licenses.licx file to the project with this single row content:

Code: Select all

Devart.Data.Oracle.OracleConnection, Devart.Data.Oracle

I use the .NET Core 1.1 target runtime. The program works correctly on Windows. When I copy the published folder to a docker container running CentOS Linux I get the following error:

Code: Select all

What is causing the "Devart.Common.LicenseException: Feature is not supported" error? My goal is to evaluate if our organisation can use dotConnect for Oracle on a CentOS/redhat docker container.

I solved the issue by adding the string "license key = trial:/absolute/path/to/Devart.Data.Oracle.key;" to the connection string. I don't find this anywhere in the documentation. It was only in a post in this forum. Please add it to the documentation.

Thank you for confirming the fix.

The documentation is updated. It will be uploaded (available in public) soon.
