I have encountered the following error several times and I am sure that I will continue to encounter it in the future.
Unable to activate Windows Store app. The activate request failed with error ‘This app failed to launch because of an issue with its license. Please try again in a moment.’
If you come across this error when you fire up Visual Studio, you may end up doing a lot of things to try to resolve the problem. Several that come to mind are:
- Re-starting Windows
- Re-starting Visual Studio
- Modifying your package manifest
None of these actually fix them problem. It turns out that the majority of time that you encounter this problem is because you have already installed the solution into start screen. I would recommend that anytime you encounter this error, that you always first uninstall the application from the start screen and then try to run it from Visual Studio again.
Hope this helps…
I am excited to be presenting with my friend Brian Hitney tomorrow night at the Charlotte Enterprise Developers Guild.
Here is a summary of what we will be presenting:
Windows 8 opened up a whole new set of possibilities for application developers in terms of how their applications can interact with the underlying operating system, with other applications as well as with the users. Specifically this includes the ability to utilize Contracts (search, share, settings) to give the impression your application is ‘one’ with the operating system as well as creating live Tiles to allow your application to communicate with the users even when the application is not running. In this session we will take a look at how you can use Contracts and Tiles to provide your application a great user experience and make your users feel truly engaged.
Hope to see all of you there!
Congratulations to Thomas Griffin and Chris Bordeman for winning a free copy of MVVM Survival Guide for Enterprise Architectures in Silverlight and WPF.
Hope enjoy the book!
I am very excited to announce our next Windows 8 DevCamp series! I will be speaking with Brian Hitney.
Join us this Friday, Oct 5th, from 9am – 1:30pm
Here is a summary of our event:
By popular demand, we’re continuing the Windows 8 DevCamp series! We want to make sure your app is ready for primetime, so at each DevCamp, we’ll dive into a specific feature and then go hands on with your app, or using our reference app.
In this DevCamp, we’ll dive into Tiles and Notifications using our Contoso Cookbook reference app. Live tiles are essential to adding an interactive experience to your application, and we’ll show you how to update live tiles either through a local background task, through the application itself, or have Windows 8 poll a service to update its content. We’ll also show how to leverage the Microsoft Push Notification service to push notifications down to users. Applications can also create secondary tiles that allow you to deep link to specific content or pages within your app. We’ll also spend a few hours going hands on to ensure the best experience for your app!
You can registere here. Hope to see you there….
I wanted to follow-up on the presentations I gave during the Windows 8 DevCamp in Charlotte. Here are the slides from the two presentations:
Here is a link to the source code for ContosoCook:
I found a sample of Contoso Labs based on the Release Preview. If you want to use the HTML labs be sure to follow these steps required to get the code to work based on the RTM:
As you are doing your development, be sure to adhere to the UX guidelines for Windows Store apps here. You can download PDF of this here:
Finally and probably the most important is the full set of code samples for developing Windows 8 applications:
Thanks to all who came out and are interested in doing Windows 8 development!
Hope this helps…
Recently, I have been playing with a lot of sample code on Windows 8 development and I have ran into a couple of issues while trying to get the demos or code that I have written on another computer to run. As soon as you try to run the application, you get the following exception:
Error: DEP0700: Registration of the app failed. An internal error occurred with error 0x80073D05. See http://go.microsoft.com/fwlink/?LinkId=235160 for help diagnosing app deployment issues.
Here is a screen shot of the same:
If you haven’t worked a lot with Windows 8, you may not where to look as far as correcting this error. If you take a look at the package.appxmanifest file in Visual Studio 2012 and go to the Packaging tab, you will see the following:
I discovered that if you change the certificate associated with the application, you can fix the problem. Simply click on the “Choose Certificate…” button and you will see the following pop-up:
Next click on the “Configure Certificate…” drop-down and chose “Create Test Certificate…” and you will see the following pop-up:
Once you have done this, you should be able to run your application successfully.
- I read another post, that mentioned that if you log-out and log back in, you can then run the application without any issues.
- I found this post on the msdn forums that mentioned if you changed the package identity, things would work. However, according to here, your package name is unique to your Windows Store developer account and I don’t think it is a good idea to change it.
Hope this helps…
I am excited to be presenting September 8, here in Charlotte for the Windows 8 DevCamp! It is going to jam packed with great content and information to get you up to speed for delivering excellent apps to the Windows app store. Here is a quick snippet of what we are going to cover:
Windows 8 Overview and the Windows Store
Haven’t seen Windows 8 or know what it takes to get an app in the Windows Store? We’ll cover that here. Drink your coffee because this first session will dive quickly into Windows 8, the platform, the changes, and the Windows Store, allowing you to monetize applications in a number of ways from in app purchases to subscriptions to trials.
Cookbook I: Design Templates and Style
In this session, we’ll talk about the design principles for Windows Store applications — controls, color, typography, and general guidelines to follow to deliver the best user experiences. We’ll also dive into the development choices and tooling support available. We’ll begin with the built in templates and show how we can quickly scaffold a data-driven application called the Contoso Cookbook.
Cookbook II: Data, Contacts, and Settings
You’ve seen the Cookbook. But, how do we leverage data? How do we expose our data to allow users to search and share from the app? We’ll explore these options in this session, from storing data, retrieving data via a web service using an in app purchase, to implementing search and sharing contracts, we’ll look at the code that makes this possible. We’ll also show how to store data locally, as well as roam preferences that can follow a user automatically as they log in to different devices.
Cookbook III: Application Bar, Tiles and Notifications
We’ve got the Cookbook well under way; now it’s time to add some polish. We’ll look at using the app bar for common tasks, and spend time talking about leveraging “live tiles” to create an up-to-date, engaging tile for your application. We’ll also look at using Notifications, and how applications can run either background agents for various tasks, or be notified from a remote service using the Windows Notification Service.
Hands On: [Your App Here]
Now it’s your time. We’ll work in breakouts and 1:1 as necessary to get the tools and environment set up and provide guidance for building out your app. Have an app already underway? We can test, review and provide feedback against store certification requirements. As time permits, we’ll cover additional features, and talk further about the certification process. And if your app isn’t quite ready yet, that’s fine! We’re here to give you the kickstart to building your app, and we’ll be here to make sure it’s done by October 26th.
Be sure to register now as space is limited! Look forward to seeing you there and having some great Windows 8 sessions!
I had a great time presenting in Raleigh for the Windows 8 DevCamp!
As promised, I wanted to post a couple of references that you might find helpful in developing Windows 8 applications:
- Migrating apps from Consumer Preview to Release Preview
- Migrating apps from Release Preview to Windows 8 RTM
- Windows 8 Modern Style Apps
- Memory Game
- White papers for Metro style apps
- Downloads for Metro style app development
- Windows 8 Keyboard Shortcuts
Also, I have uploaded the port of the XNA Platformer game for Windows 8 in HTML here. This version targets the Windows 8 RTM.
I had a great time and hope you all enjoyed it as well…
Last night the question was asked at to where a developer could go to look at sample WPF line of business applications. Pete Brown has a blog post that allows you to download the “Book Of WPF” which I highly recommend. Also don’t forget that Visual Studio 2010, Expression Blend, and WebMatrix were also written in WPF.
Here are some other WPF applications that I thought you might like:
Hope this helps…
I had a great time speaking at the WNC .NET Developers Guild last night.
Here are the slides and code for the presentation I made on Windows 8 and building Metro applications. We had a great turnout!
Thanks to everyone who came out and have a very Merry Christmas….
