Answer 1

I was getting the exact same error. In my case the culprit was a NuGet package. It had added an app.config file to the project and it was confusing VS. I removed the app.config file and it solved my issue.

I got the solution at Iris Classon's site.

Answer 2

Playing with this issue for 3 days, tried every suggestions, nothing works. Until now!!!

The solution was this for me:

• renew developer licence
• build and deploy solution in Release mode (after this step it still not worked, but VS installed some packages in rpi)
• start VS remote debugger with default account (http://:8080/#Debug%20settings)
• configure remote device with Universal authentication mode (VS2017 -> Project settings -> debug -> target device: remote machine, authentication mode: Universal (unencrypted protocol))

...and now I can sleep.

Hope it helps somebody.

Answer 3

this can happen when the application signing key (.pfx file) is missing.

Try the following:

• Open the Package.appxmanifest file in Visual Studio
• Go to the register "Packaging"
• Select [Choose Certificate…]
  • Select the test certificate using [Configure Certificate…] [From File…], or create a new one using [Configure Certificate…] [Test Certificate…]
  • When using a test certificate, ensure that it is in the .gitignore file. There should be an entry like !**\*_TemporaryKey.pfx to include the key in Git.
    • Note: The certificate for release build should only be available to the build server and not included in Git.
• Rebuild the project

This happened to me once too, but the deleting build directories advice fixed it. I assume that this is only one project since it's a Hello World app; otherwise I would ask if you deleted build directories from all projects in your solution.

You can also try running "Clean Solution" from the BUILD menu in Visual Studio.

I'm sorry...it's horrible if this is happening on a clean install as you describe.

Answer 5

Because of Two things i resolved this issue.

1. Basically, we just need to delete the bin\Debug and bld\Debug folders in our projects. Those contents will be regenerated by Visual Studio when you rebuild project.

2. Just Restart the Visual Studio. And Clean Build and Rebuild the solution and RUN it.

Hope this helps.,

Increasing the revision number of the package worked for me
