I've been getting this error whenever I open a serialized file (binary) created an older version of the application (before I was working here). It looks like this:
Exception:
"Exception has been thrown by the target of an invocation." System.Reflection.TargetInvocationException
Inner expection:

You just don't seem to get enough info from the error. How do you go about debugging an error like this?

I have code in my Facade layer to make calls to active directory
activeDirectoryUserCache = new MyFacade()
.GetActiveDirectorySearchResults(MyEnum.MemberCategory.User);
This call works fine in my local machine. But when the same is deployed to DEV server, it throws the following exception.

As I understand the active directory call works with the Principal Objects and I believe they are not serializable by default and I cannot mark them as they are .net reserved objects. But what should I be doing in order to get rid of this issue?
I am using System.DirectoryServices.AccountManagement; namespace for AD Get users and groups calls.
So I get this exception from Telerik's RadGrid when using a custom DataSource but I have no idea what I am doing wrong. Any clues?

This error is happening due to some kind of (probably accidental) recursion. I'd suggest the following:
Look for something that triggers a redraw in your redraw code.
Look at your call stack when it fails and see where it is entering this endless recursion.

I have not changed any security configuration in the system. The specific account under which the assembly is loaded has administrative privileges. Any idea of what could cause this issue? I have run through the web extensively, but in vain.
I am developing a C# WPF project with an embedded SQLite Database. I have used SQLite before without problems but for some reason when I call:
SQLiteConnection conn = new SqliteConnection("my connection string");
However, when this code executes it displays the error
XamlParserException was unhandled
Cannot create instance of MainWindow.xaml defined in assembly 'MyProject', Version=1.0.0.0...
Exception has been thrown by the target of an invocation. Error in markup file 'MainWindow.xaml' Line 1 position 9.
At this position is the following code in the XAML file
<Window xmlns:my="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Input.Toolkit" x:Class="MySQLBackup.MainWindow"
I have set the project to be .Net Framework 3.5 so I do not understandw why I am getting this error and why it is saying it is an error in the XAML when it calls the SQLiteConnection in the class file.
Thanks for any help you can provide.

I've managed to resolve it. I think it was something to do with the user.config file that is created by the application. I deleted the user.config and then told visual studio to rebuild and then it seemed to work.
Thanks for your help
I'm writing a Visual Studio 2008 add-in and all was working fine, but few days, sometimes, there are strange errors about Serialization (unable to find assembly).
My addins compile work, and runtime too.
When open new instance Visual Studio, my addin fails when click menu option.
but then if open solution all works (few sometimes fails)
code:
private void AbrirFicheroMfa()
{
using (Stream containerStream = File.OpenRead(this.FicheroMFA))
{
mfaContainer = this.Deserialize(containerStream);
containerStream.Close();
}
}
public MfaContainer Deserialize(Stream serializationStream)
{
var formatter = new BinaryFormatter();
return (MfaContainer)formatter.Deserialize(serializationStream);
}
error:

any suggestions ?
update:
once I get this error:
SerializationException:
[A]COMPANY.LifeCycle.Mfa.MfaContainer
cannot be cast to
[B]COMPANY.LifeCycle.Mfa.MfaContainer.
Type A originates from
'COMPANY.LifeCycle.Mfa,

PublicKeyToken=null' in the context
'LoadFrom' at location
'C:\Projects\Addins\Mfa\COMPANY.LifeCycle.Mfa.dll'.

'C:\Documents and Settings\eprados\Configuración local\Datos de programa\Microsoft\VisualStudio\9.0\ProjectAssemblies\wi3h64z601\COMPANY.LifeCycle.Mfa.dll'.
I have an WinForms application and all is work. Serialization is ok.
For VS Addin, I have:
Addin.dll references
ComunDespliegue.dll and
LifeCycle.Mfa.dll
ComunDespliegue.dll references
LifeCycle.Mfa.dll
For WinForms app, I have:
UI.Client.dll references
ComunDespliegue.dll and
LifeCycle.Mfa.dll
The assembly reside in the addin directory alongside my addin. the type i'm serializing is serializable. The COMPANY.LifeCycle.Mfa.dll is the same.
Use Fuslogvw.exe to find out where the CLR looked for the assembly. There are two basic reasons. First is that you incremented the [AssemblyVersion] of the assembly in a recent update and are trying to deserialize data that was saved with the old version of the assembly.
The second is that it simply cannot find the DLL. There are but a few places where you can store an assembly so that it can be found when VS is running. Either the GAC or the PrivateAssemblies or PublicAssemblies subdirectory of Visual Studio's Common7\IDE directory.
