MS CRM 2011 First Connection

Question

I am having a trouble with Microsoft Dynamics CRM 2011. I would like to get a first connection in C#. I have all information to connect the CRM. I can do this on the browser.

Also I should add/remove a new record (if user fill contact form and press the button, I should add him to the CRM successfully).

Is there any clear and understandable example? I found something that confused my mind.

you can connect to CRM like this:

put this in your app-config to the "connectionStrings"-Tag:

<add name="MyAppConfigString" connectionString="Url=http://myserver:5555/myorg;Domain=mydomain; Username=myuser; Password=mypassword"/>

this is how to add a contact to CRM 2011/2013

var connection = new CrmConnection("MyAppConfigString");

using (var service = new OrganizationService(connection))
using (var context = new OrganizationServiceContext(service))
{
    var contactRecord = new Entity("contact");
    contactRecord.Attributes.Add("firstname", "Peter");
    contactRecord.Attributes.Add("lastname", "Jackson");

    context.AddObject(contactRecord);
    context.SaveChanges();
}

to delete a record, simple use this:

service.Delete("contact", myRecordId);

to retrieve a record you could use linq:

var query = context.CreateQuery("contact");

var result = query.FirstOrDefault(r => ((string) r["lastname"]) == "Jackson");

if(result != null)
{
    var recordId = result.Id;
}
