When I try to run my Windows Store app, it won't, and shows me this:
..."does not support the contract specified"? What contract? I'm not implementing any contract; I assume it means the Settings contract or some such, but I'm not doing any of those yet.
I went to the Help page suggested, and it says, in part, "To diagnose these errors
There are no sure ways to fix these errors. Use these techniques to diagnose the problem."
The first suggestion is:
Open Event Viewer (on the Windows Start menu, search for Event Viewer.) In Event Viewer, navigate in the tree to the Application and Services Log\Microsoft\Windows\Apps folder.
Filter the view to event Ids: 5900-6000
Examine the log and see what occurred.
Windows 8.1 only brings up web pages when I search for "Event Viewer"
Actually, I did write a utility to catch event logs, and I ran that. I found these:
***Type: Error

But where is "Microsoft-Windows-TWinUI/Operational log"?
The second suggestion on the Help page was:
Use the native debugger
Configure the project to run under a native debugger.
In Visual Studio, set the Debugger Type to Native Only on the Debug (Debugging in C++ and JavaScript) page of the property pages of the start-up project.
Look at the exceptions being thrown by looking at the output window. You might want to configure the debugger to stop when these exceptions are thrown.
I did that, but it gave me no more information than previously - nothing at all displays in the Output pane.
What could be the cause of this?
UPDATE
Just to update the progress:
Based on Iris Classon's suggestions, I went to Control Panel to see if my app was installed so that I could uninstall it, but it's not in that list.
If I search for the app by typing its name, it tries to start up - its splash screen displays, but goes no further than that.
I went to Program Files\WindowsApps, and when selecting it got, "You don't currently have persimmons to access this folder, click continue to continually get access"
That leads me to "You have been denied permission to access this folder; to gain access to this folder, you will need to use the security tab"
Click the "security tab" link takes me to that tab, and a "For special permissions or advanced settings, click Advanced"
I do so.
That takes me to a Permissions tab, which says, "You must have Read permissions to view the properties of this object; Click continue to attempt the operation with administrative permissions"
I then selected (one at a time, as that is all it allows):
Trusted Installer : Full control
System: Read, Write, and Execute
System: Full Control
Administrators: Read & Execute
But so far, none of that seems to do anything good.
UPDATE 2
This problem has just "gone away" today; I don't think it was anything I did. I added a UserControl, tried running the app again, and now it runs - I don't see that error message. However, I do see a seemingly unrelated one. (at least I got further).
I just had this problem on a fresh install of Windows 8.1 on my laptop. I'm not sure which one of these steps solved it, but until somebody can give you a more exact answer here is something to try as I am sure you are keen on coding.
Only Store Apps run from VS gives that error, other Store apps work fine.
I first of all changed permissions on my WindowsApps folder under Program Files and made sure that I had full access to the folder and sub folders. Restarted the laptop, still no luck.
Then I set up an admin guest account (just something I tend to do for when I need to record tutorials- so not related to trying to solve the error). Out of curiosity I tried to create and run the same Windows Store App and got an error that another user had installed the app. Strange, how was it installed if it gave me the error that it couldn't activate the app on the main account?
I logged back in as the main user and uninstalled the application (which was showing up as installed), and I can now run any Store App from VS without problems.
Not sure this is an answer since I'm not sure what made it work, but give it a try and hopefully somebody else can clear this us up. I'll investigate further, but I'm on a train right now with poor WiFi connection :)
Best of luck!
I had the same scenario, here are the steps I did to resolve:
I tried to create packages, chose not to associate with the store.
It said that the certificate is expired, I created a new test certificate.
I created the test packages successfully.
Tried to run the project from VS and it finally ran.
I believe all of this had to do with the certificate. very frustrating and time wasting issue.
I also had the same problem and following steps fixed it. Hope it will help some one else.
Open the appxmanifest file
Go to "Packaging" tab
Select "Choose Certificate" and select "Pick from certificate store" and select your cetificate and click on ok
I created a simple Vaadin 6 application. By right clicking that project in eclipse i created simple custom widget and try to run. Error occurs which says
Failed to load the widgetset:/testcomapp/VAADIN/Widgetsets
com.example.testcompapp.TestcompappWidgetset.nocache.js?1409642685672
this error is in the form of alert box on browser. No error in Eclipse's Console.
I don't know what is wrong with it. I haven.t write a single line by myself
Note: I am using VAADIN 6
I got an answer for my question. Hope it will help anybody of u. This error will be removed by compiling the widget by pressing ctrl+6. Very easy solution
I have created a small app for Windows Phone 8. When I run it I get the following error:
((System.Windows.Application)(this)).MainWinndow threw an exception of type System.NotSupportedException at System.Windows.Application.get_MainWinndow()
I have searched for a solution to this but not much information out there.
My main page is called WelcomePage.xaml which is the first page that gets loaded and when exception is thrown during test on emmulator, but I'm not sure if that is the problem or even how to check if it is. My thinking being that I changed the name of MainPage.xaml to WelcomePage.xaml and this has maybe upset something.
Any ideas how I would go about solving the above problem, apologies I'm new to VS and Windows Phone C#?
J
Have you checked WMAppManifest.xml file in Properties path?
In the Application UI Tab, the Navigation Page should be changed to WelcomePage.xaml but not MainPage.xaml.
I'm working on an Android/iOS app using Adobe AIR. The app appears to work normally both inside Flash Pro and real devices except for the following test:
Do Publish Preview inside Flash Pro.
Close the preview window.
The error appears in the Output panel:
Error: Error #1503: A script failed to exit after 30 seconds and was terminated.
at [*code location is a for loop inside writeExternal() of a class saved to a Shared Object*]
Test Movie terminated.
This happens with AIR3.4, but not AIR3.2. I did a lot of code checking, tracing, etc. but still can't figure out what's wrong. Any suggestions?
