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:
System.Web.HttpException (0x80004005): Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode. ---> 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.

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.

You need to mark the type/s your pushing in to SessionState as serializable, with the [Serializable] attribute.
I recently have this strange issue with IIS. We have an ASP.NET website and recently it fails after an application pool recycle. When I stop the applicationpool, clear the "ASP.NET Temporary Files" and restart the applicationpool. It works again. When i manually recycle it, it breaks again. I can reproduce this every time. The big problem is that our web application recycles every night.
Can I in some way prevent the usage of these ASP.NET Temporary Files? Or how could i fix this issue.

I am developing a code first web app in Visual Studio 2012 Express.
I use this connection string in the web.config:
<add name="myContext" connectionString="Data Source=.;Integrated Security=True;Initial Catalog=cityKingMVC4" providerName="System.Data.SqlClient" />
I am using SimpleMembership.
I am trying to seed 1 administrator from Filters/InitializeSimpleMembershipAttribute.cs:
...
WebSecurity.InitializeDatabaseConnection("myContext", "Users", "UserId", "Email", autoCreateTables: true);
// A: Create Admin user
if (!WebSecurity.ConfirmAccount("admin#mydom.com"))
{
WebSecurity.CreateUserAndAccount("admin#mydom.com", "password");
}
// B: Create admin role if not exist
if (!Roles.RoleExists("Administrator"))
{
Roles.CreateRole("Administrator");
Roles.AddUserToRole("admin#mydom.com", "Administrator");
}
If I comment A & B it doesn't crash. If I don't I get this:
The "WebSecurity.InitializeDatabaseConnection" method can be called only once.
If I debug and put a breakpoint on 'WebSecurity.InitializeDatabaseConnection' - it only calls it once and there is no other code calling WebSecurity.InitializeDatabaseConnection anywhere.
If I debug - it crashes on a different line higher up in the file (standard SimpleAuthentication file):
LazyInitializer.EnsureInitialized(ref _initializer, ref _isInitialized, ref _initializerLock);
with this error:

The problem ...
is that InitializeDatabaseConnection calls WebSecurity.InitializeProviders internally, and this method is not thread-safe, then combine this with the fact that WebSecurity typically needs initializing from various places. This has implications as web applications are inherently multi-threaded environments ... and WebSecurity.Initialized and WebSecurity.InitializeDatabaseConnection are not thread-safe when used together - they create a typical race condition.
Seeding (for migrations) means that your WebSecurity can be initialized more than once as you may also need to initialise it in Global.asax.cs for deployments with seeding turned off, and your InitializeSimpleMembershipAttribute can potentially be called multiple times simultaneusly by http requests in live deployments etc.
Putting the initialisation code in multiple places also breaks your DRYness
The solution ...
Make sure your init calls are thread-safe, and only occur once per instance of an AppDomain. Use a thread-safe singleton class to do this; and reduce duplication of code.
Call the singleton's EnsureInitialize method from any/all of the following, as appropriate for your application:
Global.asax.cs (Application_Start method before anything else)
Migrations\Configuration.cs Seed method (before creating the users)
Filters\InitializeSimpleMembershipAttribute.cs (in the SimpleMembershipInitializer constructor after the context is initialised)
Here is a simple example singleton:
// Call this with WebSecurityInitializer.Instance.EnsureInitialize()
public class WebSecurityInitializer {
private WebSecurityInitializer() { }
public static readonly WebSecurityInitializer Instance = new WebSecurityInitializer();
private bool isNotInit = true;
private readonly object SyncRoot = new object();
public void EnsureInitialize() {
if (isNotInit) {
lock (this.SyncRoot) {
if (isNotInit) {
isNotInit = false;
WebSecurity.InitializeDatabaseConnection("MyContextName",
userTableName: "UserProfile", userIdColumn: "UserId", userNameColumn: "UserName",
autoCreateTables: true);
}
}

Once I had done this, my case of the error you mention disappeared, not to be seen again.
Footnotes
The singleton class also keeps your code DRY, which is especially useful during early stage app development if you need to later change the configuration of your WebSecurity.InitializeDatabaseConnection as it will only be in one place (end edit)
I also keep the SimpleMembershipInitializer clean, and instead seed my users along with the common seeding in Migrations\Configuration.cs Seed method. This helps with testability of seeding through my migrations by keeping everything in one place. I use unit testing to make sure we can always go up and down the migrations tree, so this makes it easier to do that.
However the location of your seeding code won't matter, it is more just making sure that, globally, you have initialised WebSecurity only once within your AppDomain, and that any call to InitializeDatabaseConnection is thread-safe.
Add this code to Global.asax.cs. This will makes sure that your database is always Initialized before any other executions. Also make sure its the first registration in Application_Start()
if (!WebSecurity.Initialized)
WebSecurity.InitializeDatabaseConnection("DefaultConnection",
"UserProfile", "UserId", "UserName", autoCreateTables: true);
Get rid of Filters/InitializeSimpleMembershipAttribute.cs or just comment the code inside, in case you would like to go back to it.
Remove [InitializeSimpleMembership] at the top of AccountController.cs
Also if you haven't already enabled migrations, i would encourage you do so. That way, you can do your seeds in Configuration.cs created inside the Migration folder when you run Enable-Migrations
If it is already initialized then make sure your first call:
if (!WebSecurity.Initialized)
{
// Do the initialization first.
}
// The rest of the code
This way you'll be sure that you don't repeat the initialization process.
Do you also have the InitializeSimpleMembership attribute on your AccountController class? (this is the default). If so, you are initializing twice.
To make sure that the WebSecurity.InitializeDatabaseConnection is not called twice just use the WebSecurity.Initialized to check if it was already called. This blog post provides detailed instructions on seeding and customizing SimpleMembership. There is a series in this blog on using SimpleMembership and I would also recommend looking at decoupling SimpleMembership from your ASP.NET MVC Application. You can get the complete source code for these examples here.
I have an MVC application and it has essentially two stacktraces, im wondering why there are two of them though?..

One is a stacktrace of an inner exception.
It looks like you first got a MissingMethodException, with reason
No parameterless constructor defined for this object.
That caused an InvalidOperationException, with reason
An error occurred when trying to create a controller of type 'PteDotNet.Web.Controllers.BlogController'. Make sure that the controller has a parameterless public constructor.
So apparently your BlogController needs a parameterless constructor.
I'am not completely sure, but It looks like the Root Cause:
The MissingMethodException is fired first, then the InvalidOperationException gets fired, because of the first Exceptin
The InvalidOperationException is the exception thrown, but it is thrown as a result of a MissingMethodException and this exception is included as the InnerException of the InvalidOperationException. The InvalidOperationException explains what went wrong but looking at the InnerException you can see where the failure was triggered in the first place.
When you evaluate ToString() on an exception with an inner exception you get stack traces of all nested inner exceptions to help you understand the problem. A common mistake is to use ex.Message + ex.StackTrace for diagnostics purposes but you loose information about inner exceptions. Unless you want to hide this valuable information you should always use ex.ToString() when logging exceptions.
In the MVC framework there is code similar to this:
try {
// Will throw MissingMethodException if there is no parameterless constructor.
var controller = Activator.CreateInstance(type);
...
}
catch (MissingMethodException ex) {
var message = String.Format("An error occurred when trying to create a controller of type '{0}'. Make sure that the controller has a parameterless public constructor.", type);
throw new InvalidOperationException(message, ex);
}
So instead of getting a MissingMethodException which might confuse you, you get an InvalidOperationException with a nice explanation. This is an example of best practice when it comes to exception handling.
I've added a custom attribute ("custom_contacttype") to the Contact entity. This attribute is of type picklist which is comprised of seven values. I'm developing using Advanced Developer Extensions for Microsoft Dynamics CRM against CRM 4.0. After I set the value for this attribute and call SaveChanges() I get "Object reference not set to an instance of an object." error. I've been battling this one for a while. What am I doing wrong? Below is my code:
var crm = new CrmDataContext(context.Connection);
var saveContact = crm.GetEntities("contact").Where(p => p.GetPropertyValue<Guid> ("contactid") == contact.Id.Value).Single();
saveContact.SetPropertyValue("custom_contacttype", 2, typeof(Picklist));
crm.UpdateObject(saveContact);
crm.SaveChanges();
Trace Log from CRM Server:

Looking at the stack trace, the error is actually being thrown in a plugin, not in the code you have pasted above. Look at this line in particular:
Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.
at AccessCRM.PluginUtilities.GetStringValueFromProperty(Property p)
at AccessCRM.ChangeLogContactData.Execute(IPluginExecutionContext context)
You'd need to post up the code for that plugin for us to have another look.
Alternatively use Remote Debugging to debug this yourself.
