LicenseException with PgSqlAlerter on .net core 2.0

Post by evk » Wed 24 Jan 2018 12:34

I create PgSqlAlerter like this in .NET Core 2.0 application running on linux (CentOS 7):

Code: Select all

    _dbListener = new PgSqlAlerter(new PgSqlConnection(cs), _syncItemName);
    _dbListener.Alert += OnDatabaseNotification;
    _dbListener.Error += OnDatabaseListenerError;
    _dbListener.Stopped += OnDatabaseListenerStopped;
    _dbListener.Start(); 
    
Where `cs` is connection string with "License Key" parameter with valid (non-trial) license key. This connection string works for regular database queries, but doesn't work with `PgSqlAlerter` which gives the following exception in `Start`:

Unhandled Exception: Devart.Common.LicenseException: Feature is not supported.
at d.le.clv.Vld(Int32 pe)
at Devart.Data.PostgreSql.PgSqlAlerter.Start()

Is PgSqlAlerter not supported on .NET Core or is it something different?

Thank you for your report. We have reproduced the issue and will notify you when it is fixed.

As a workaround, please call conn.Open() before using PgSqlAlerter. This will avoid a license check by PgSqlAlerter.
