quartz_jobs.xml is parsed with error in xml document (x,y)

I'm trying to install quartz.net 2.2.4 and run a helloworld simple job. But I'm not able. quartz_jobs.xml is not parsed. It is obviously read but quartz fails to parse it. Log gives me the following error each time I try to launch scheduler in my console application.

ERROR | Error scheduling jobs: Error in xml document (2,2)

jobs.xml is a valid xml. moreover any other valid xml will give me the same error. If i try to feed quartz with invalid xml it shows something like

ERROR | Error scheduling jobs: Element XXX is missing an end tag

Please advise.

Here is app.config

<configSections>
<section name="quartz" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089" />

My quartz_jobs.xml

Here is Console Application Main

    static void Main(string[] args)
    {
            ISchedulerFactory sf = new StdSchedulerFactory();
            IScheduler sched = sf.GetScheduler();
            sched.Start();
     }
