I am getting the following error in Silverlight for one of the users. The target runtime is 4.1.10329.0 and the application is built using Silverlight 4. I don't happen to understand what may be the issue. Looks like it is trying to load something on LoadComponent and failing:

Open IIS on the server, go to HTTP headers, click on Mime Types, click “Add New” and add the following:

I am experiencing a problem at application startup from time to time on production machines. It doesn't happen every time the application starts, and apparently it only happens on reboot. The application is started from login, added to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run.
Apparently, the problem is more frequent when resetting the machine, than during a reboot. Starting the application manually after it crashes is successful.
The following exception is thrown during startup:
Initialization of 'System.Windows.Controls.TextBlock' threw an exception.
System.Windows.Markup.XamlParseException: Initialization of 'System.Windows.Controls.TextBlock' threw an exception. ---> System.InvalidOperationException: The calling thread cannot access this object because a different thread owns it.

As seen from the StackTrace, there is something going on while updating style cache. I haven't been able to reproduce this on my own computer. There are no threads involved here while starting the application, but there are a few AppDomains. The origin of the exception is not always the same, but it is exactly the same from Application.LoadComponent(Object component, Uri resourceLocator)
Because our application needs to find the configuration file from a different location than the executable (..\ProgramData....) depending on the OS, we use a separate AppDomain where we instruct it where to look for the configuration file, as we could not find any better solution of telling ConfigurationManager where to look for the file. It could of course, be related to this, though not necessarily. EDIT: ConfigurationManager.OpenMappedExeConfiguration Doesn't seem to work, as it won't refresh any user or application settings accessed through Properties.Settings.Default, etc.
Does anyone have any suggestions or recommendations on how to deal with this? Sorry I am not able to provide you with a sample to reproduce with.
That exception was because you are modifying a visual element from a thread that is not the visual one. I know this because in the first line of your exception it said:
Initialization of 'System.Windows.Controls.TextBlock' threw an exception. System.Windows.Markup.XamlParseException: Initialization of 'System.Windows.Controls.TextBlock' threw an exception. ---> System.InvalidOperationException: The calling thread cannot access this object because a different thread owns it.
All the rest of the exception doesn't matter. I think it is when you are loading the initial configuration, then you use other thread. The random behavior could be that some time you find the configuration before the TextBlock control is loaded, so this times the exception will no be thrown.
To solve this please take a look to this question, and the last answer that I give (the one that use the SynchronizationContext, that really works with WPF application that use several threads). If is not clear comment and I will write the solution here.
Hope this answer helps to find that random error, its are the worsts...
I'm not sure what is causing this exception but I there is a workaround to your problem.
Instead of creating a separate AppDomain just for loading a different configuration file, you could use ConfigurationManager.OpenMappedExeConfiguration which allows you to load any .config file from anywhere in your local file system.
You use it like this:
//Map the new configuration file.
var configFileMap = new ExeConfigurationFileMap() { ExeConfigFilename = #"c:\myOther.config"};
//Get the mapped configuration file
System.Configuration.Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configFileMap, ConfigurationUserLevel.None);
Use config.GetSection() to get specific sections for read-only use or directly the config object to change the configuration at run-time.
And you will not need the different AppDomain which will mean faster startup time :)
Getting rid of the extra AppDomain used to specify configuration file, and replacing it with the method specified in this link took care of the problem.

Can any one please help me to fix this error
This is a very generic error. You may want to look through your Event Log to see if there are other errors that occur at the same time more related to your specific module. Debugging the module to see what exception is coming from your module can also be helpful, rather than trying to unwind these stack traces that, more than likely, are going to be wild goose chases.
What often happens with DNN is that a module fails while loading, and then other parts of the skin and container fail because the module was never fully setup correctly. These are the NullReferenceException errors that you're seeing.
bdukes said the main things I would guess anyway keep the following problem in mind, too.
another reason for this problem could be a specific servertag used in a dnnwrapper.
for example if you are using telerik wrapper from dotnetnuke but placing telerik controls in this wrappers without having a refference on the telerik assambly.
example:
<dnncontrols:datepicker>
<calendar>
<SpecialDays>
<telerik:calendarDays />
</SpecialDays>
</calendar>
</dnncontrols:datepicker>
If you are doing this you will get a nullreference as you got. This Problem drove me crazy to find it so I decided to post it here.
I hope this will help you.
But at first I would suggest the way bdukes described (this is the normal way to go).
best regards
In which situation following error occurs?
Unable to cast object of type 'MyType' to type 'Castle.Proxies.MyType'.
UPDATE:
I got this error message while binding MyType.FindAllByProperty("col1", "foo"); to a GridView (exactly a Telerik's one: RadGrid). This error is not occuring every time, just sometimes. Here is markup of my grid:
<telerik:RadGrid ID="grdList" runat="server" AutoGenerateColumns="false" OnNeedDataSource="grdList_NeedDataSource"
OnUpdateCommand="grdList_UpdateCommand" AllowAutomaticUpdates="True" OnItemUpdated="grdList_ItemUpdated"

</Columns>
</MasterTableView>
</telerik:RadGrid>

This exception probably comes from the code trying to re-attach a proxied/lazy-loading entity to a session. The most likely API call to throw this exception with a newer NHibernate (I don't have problem with 2.1 but I do have problems with latest) is Session.Lock(obj, LockMode.None).
If the programmer of this component first evicts the entity from the ISession and then re-loads it (perhaps cached?) into another one by id, or performs ISession.Update this problem should go away until the NHibernate team has figured out the underlying problem.
I had a similar problem with EntityFramework 6.0.
I had migrated from an old version of EntityFramework that did not use proxies and had some code that created and attached new instances of the entity via new MyEntity();.
My solution was to use dbContext.MyEntity.Create(); instead so I only work with proxies. Something similar should be available for NHibernate if I recall correctly.
My error was:
Unable to cast object of type 'MyProject.MyEntity' to type
'System.Data.Entity.DynamicProxies.MyEntity_849E94C98E5E543D6DF5245252144E3EAC00131F811886276B6ABD991719D232'
We ran into the same issue with RadGrid having AutomaticInserts. After inserting an item it throw InvalidCastException: Unable to cast object of type 'MyDbModel.Role' to type 'System.Data.Entity.DynamicProxies.Role_...' in DataBind() at Rebind().
The issue was gone after I adapted the DataBinding to have an OrderBy().
I'm getting the error "Invalid URI: The format of the URI could not be determined" when customizing it. I've made several changes to the configuration files and UI, but I keep getting this error. It isn't logging it too in the event log nor the log files, which makes it very annoying to debug. So how do I figure out where the error is coming from? Is it with the URL that's pointing to the ReportServer2005.asmx file, or something else?

UPDATE: I've build a WPF app with no code behind, just put in a TextBox and a button and built it. When running this application I can see the same error in this user's machine. You can click on the button, and it works ok, but as soon as you press a key on the keyboard the application throws the same error. Should I reinstall the .Net Framework? Any other recommendations?
Original question:
I have a WPF app distributed via ClickOnce in an enterprise environment. Dozens of users are running my app without issues. However there's 1 single user who can't run the app. If I log-in in his machine I also get an error. The error for the user is the standard error message when any exception occurs. So I needed to remote-debug it.
The program loads without issues and it places the focus on a TextBox as soon as the TextBox looses the focus or the user presses a key, the program crashes.
I've attached my visual studio to the my application running on the problematic machine and I managed to capture the following stack trace.

I put all kinds of traces in the code and I am pretty sure that my code is not directly causing this exception. I do not have any KeyUp events in my code.
What do you suggest?
Thanks a lot
My Psychic Debugger says it's something to do with the tablet input service. Office tends to install weird versions of it, which cause problems. What version of Windows is it?
Paul, you gave me a great hint. The Windows language bar had handwriting and voice recognition options turned on. When I turned these options off my app works fine!
What's up with that??!?!?!?!
