I am facing this problem a while. Sometimes (just sometimes) i am getting ThreadAbortException in Page_PreRender of one my aspx pages.
this is so odd, i get it sometimes in somedays. I am using SQLite with NHibernate in an asp.net website hosting in a shared webhost.
The exception is :
System.Threading.ThreadAbortException: Thread was being aborted.

do you have any idea ??
It's possible that your code took too long to execute (because of too much data, or because SQLite is waiting for another thread's lock on the database).
Try increasing httpRuntime's executionTimeout in the web.config.

This error was happened on-and-off when executing the asmx service in background schedule job in production server. In my localhost it work fine. I had try to solve this thread abortion issue by adding System.Web.HttpContext.Current.Server.ScriptTimeout to 90 seconds and longer when process the background job but it still persist. The thread abortion sometimes might occur in different stage but mostly occurs in below stack trace.

Getting "Unable to serialize the session state" error, where I'm trying to store HttpSessionState object in Session. Below is my code which is causing issue. Since HttpSessionState is not serializable class and trying to put into session.
Public Shared Property CurrentSession As HttpSessionState
Get
Return TryCast(HttpContext.Current.Session("CurrentSessionObject"), HttpSessionState)
End Get
Set(value As HttpSessionState)
HttpContext.Current.Session("CurrentSessionObject") = value
End Set

You need to mark the type/s your pushing in to SessionState as serializable, with the [Serializable] attribute.
When I run the following code :
var db = Database.Open();
var contact = new Contact() {FirstName = "Mark", LastName = "Rendle"} ;
db.Contacts.Insert(contact);
I get an error :

Error on my part.
Another Library I am using requires classes to have fields opposed to properties.
I was coding against the fields not properties.
I have an ASP.NET webservice that is making use of Entity Framework 4.0.
When I run one of the methods on the WebService locally, it is throwing the following exception:
System.InvalidOperationException: There was an error generating the
XML document. ---> System.InvalidOperationException: To be XML

Any idea?

There is problem with the XMLSerializer you are using to serialize the WCF request across the wire. Any IEnumerable class in your object graph should have a public add method. See some details here

I am trying to move my app to out-of-proc session state and can't find which session object is failing to serialize - the YSOD stack trace is unrevealing.
Is it possible to view the objects, or at least the types of objects, currently stored in session state of a running application? Short of attaching a debugger to a running app, and having its source code available, I don't know if this is possible.
I'm using Alachisoft NCache, so here's their stack trace, though it's not helpful:

Actually your exception tells you exactly what it is: You have a UserControl that is being placed into the Session somewhere and it is not marked as serializable.
---> System.Runtime.Serialization.SerializationException: Type 'System.Web.UI.Control' in Assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable.
Update
You can put some code in a page OnLoad (or similar) that simply iterates the session and dumps that out, it's not too difficult:
foreach(var key in Session.Keys)
Response.Write(String.Format("{0}: {1}<br/>", key, Session[key]);
That's not going to identify the exact code/page but it should give you some search criteria.
