I've installed the Silverlight 4 beta toolkit and created a new silverlight business application. Without making anychanges at all, when I try to look at the Mainpage.xaml in designer view I get the following error in the designer window:
System.Reflection.TargetInvocationException

Running the basic silverlight project results in IE crashing (unsurprising given the above errors). What is worse is that I loaded an existing Silverlight 3 app and tried to examine the Mainpage.xaml there and got the same error (help!).
I've now tried this on two compeltely different pc's and got exactly the same issue.
Any ideas?

I am trying to pass user variables into an SSIS script task to use them in the similarly structured following if clause:-
VariableY= Directory.GetFiles(Dts.Variables("User::VarX").Value.ToString,
"*.*", SearchOption.TopDirectoryOnly)
For Each VarZ In VariableY
If VarZ.ToString.Contains(Dts.Variables("User::Var1").Value.ToString) Then
localVar = 1
End If
However upon executing it throws and error of the a vague nature with the statement 'exception has been thrown by the target of an invocation'. Previously in the if clause, the values were being hard-coded in the contains() function, which executes smoothly. Any suggestions to solve this?

FYI I have tried ReadOnly _xml_datatable as New ReportsData_Employee.COATSEndASsignmentDataTable() and there was still an issue.
Any help is appreciated. Let me know if there is any other information you need.
Thanks.
You haven't initialized object properly. Here...
ReadOnly _xml_datatable As ReportsData_Employee.COATSEndAssignmentDataTable = New ReportsData_Employee.COATSEndAssignmentDataTable()
Should be
Private ReadOnly _xml_datatable As New ReportsData_Employee.COATSEndAssignmentDataTable()
Your real issue is

You need to look into constructor of COATSEndAssignmentDataTable. you have NullReferenceException in there. These two lines tell you exact location

Here are some tips you may find on web, in order to fix the problem:
Reinstall VSTOR
Disable other add-ins
Install framework 3.5 sp1
Fix error in the security configuration on the computer that is running the Visual Studio Tools for Office solution
Modify/Disable custom rule of a company's virus software, blocking the .net framework ability to create the 'shadow copy' version of the vsto .dll.
Turn on .NET programmability support http://sqlblog.com/blogs/davide_mauri/archive/2010/07/30/powerpivot-not-visibile-in-excel.aspx
Move the entire solution to .NET 4.0
I am handling the current state of my WP7 app in the OnNavigatedFrom and To events so that if the app is tombstoned OR they navigate to a different page it saves the state to the inbuilt PhoneApplicationService state.
I have a simple ViewModel which I dump to the state to make life easier. When navigate to a different page within my app, the state is stored fine and restores fine (ie. I assume it is serializing at this point). However, when I tombstone the app (i.e. Start button) I am getting an unhandled error with serialization and the stacktrace is not giving me any clues as to why it is failing.
I have tried wrapping the actual call in a try catch block to try and see what is wrong but it doesn't help - it's something that the runtime is doing different on tombstoning with my object than when it just stores it between pages.
Here is my code:
protected override void OnNavigatedFrom(NavigationEventArgs args)
{
appService.State["TournamentViewModel"] = tournamentViewModel;
base.OnNavigatedFrom(args);
}
protected override void OnNavigatedTo(NavigationEventArgs args)
{
if (appService.State.ContainsKey("TournamentViewModel"))
{
tournamentViewModel = (TournamentViewModel)appService.State["TournamentViewModel"];
}
base.OnNavigatedTo(args);
}
This is the error that is generated - I really can't figure out where the problem is - how can I debug this better?

Update: By trial and error I found the problem to be the AppBar, which does not seem to be serializable. I marked it with [IgnoreDataMember] and it now throws a more meaningful error on a different problem. I would still like to know if there are any easy ways of catching this info...
Rodney,
My understanding is that when you put an object in one of the two State Dictionaries (the one off of PhoneApplicationPage and the other off of PhoneApplicationServices) it does not immediately serialize or deserialize.
If you use the Page.State to store data, it serializes your state bag when you leave the page, and deserializes when you return to the page (rather than when you add or read an object from the state bag).
If you use the PhoneApplicationService.State, serialization happens when you tombstone and deserialization when the application is re-activated (though I'm not sure if this is tied to the PhoneApplicationService.Activated event or not).
Page.State, by the way, doesn't allow sharing data between pages. Saving to PhoneApplicationService.State does allow you to do so.
IsolatedStorage.AppSettings seems to handle deserialization problems silently, so I'm not sure when that happens. Serialization, however, occurs when you call Save().
James
Well, how does your ViewModel express the way in which it's serializable? Personally I tend to try to steer clear of potentially-intricate serialization: one fairly simple option is to give your ViewModel the ability to explicitly convert itself to/from XML, and then perform that step manually yourself, saving an XDocument (or its string representation) in the application state. That way it's easy to debug the serialization step, see the exact XML being generated etc.
Of course, the use of XML here is incidental - if you can easily put everything in a CSV string, that would be fine too. Anything that you can easily inspect in terms of the serialized form before putting in application state.
I realise this is side-stepping some of the supposed benefits of the "automatic" serialization, but I've run into enough hard-to-diagnose problems with automatic serialization of arbitrary objects that I don't think the benefits outweigh the drawbacks.

After adding some NHibernate goodness to a project, I had similar problems deploying because I forgot to update the web.config file on production. Once I defined the hibernate-configuration section, everything worked.
Also happened to me when I had an empty enum defined.
That you have a MappingException included in your stack trace is key. This implies either a problem with your class mappings, or your NHibernate configuration. It could also be that your database does not contain tables or fields defined in your class mappings.
To be more specific, you would need to provide additional information.
