1. Have you ever installed dotConnect for PostgreSQL Professional Trial on your workstation before?

2. Make sure that datetime settings on your machine are up-to-date.

3. We have just sent the new Devart.Data.PostgreSql.key to your email. Replace your C:\ProgramData\Devart\dotConnect\License\Devart.Data.PostgreSql.key with the one attached.

1. No
2. I'm sure
3. Done - same problem.
It's .net core console app targeting .net core 1.0, code:

Code: Select all

        static void Main(string[] args)
        {
            string pgConnectionString = "my connection string";
            PgSqlConnection myConn = new PgSqlConnection(pgConnectionString);
            myConn.Open();//throws Devart.Common.LicenseException: 'Feature is not supported.'
        }

Try running your VS2017 via its Run as administrator context menu. Does this help?

Please copy C:\ProgramData\Devart\dotConnect\License\Devart.Data.PostgreSql.key to your project folder and add "license key = trial:C:/AbsolutePathToYourProjectFolder/Devart.Data.PostgreSql.key;" to the connection string. Does it work now?

1. Run your project in the debug mode, navigate to Debug > Windows > Modules and tell us the Version and Path values of Devart.Data.dll and Devart.Data.PostgreSql.dll loaded in the process of your application.

2. Specify the full stack trace of the exception.

3. Try running the compiled binary of your application (*.exe) via its Run as administrator context menu. Does this make any difference?

1. Try running the compiled binary of your application (*.exe) via its Run as administrator context menu. Does this make any difference?

2. Why are you using an outdated version (7.09.946)? Try the newest version of the package (7.9.980).

3. Does the issue persist with the newly created project? If yes, please upload a small test project with a compiled binary to ftp://ftp.devart.com (credentials: anonymous / yourEmail).

I have better idea - just make blank UWP app targeting build 10586 and let me know if you can establish connection with db.

UWP is not supported. There is no timeframe for this feature at the moment. We will notify you about the progress.
