Outputted program functions on my computer but not other user's computer


I've created a program that connects to Google firestore and I gave it to my friend. This program is meant to synchronize one or more character sheets together however when my friend tries to run the program nothing appears to happen.

I've tried:

  • Giving him all the files that are located in the bin\Release folder
  • Using dependencies nothing comes up
  • Installing VC redistributables
  • Installing a fresh windows install on a virtual machine
  • Checking for a settings file.

A list of things found in bin\Release

It looks like I need to somehow authenticate sessions on other computers due to the at Google.Apis.Auth.OAuth2.DefaultCredentialProvider+ line. In addition to that the at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(System.Threading.Tasks.Task) line worries me because this is a release version.

Anyway if it is an authentication issue how do I go about fixing it?

I reached out to Firebase support to see if I can get any light on the subject. To be able to run a C# application using the firestore library I would need an unimplemented feature. Something that would still allow the program to run and have a login function. Currently, this feature is implemented when creating mobile apps and web apps but not C# apps. However, it seems like it will be added in the future.

Subject: RE: Case ******34: Allow a program to run on other computers without an environment variable

Hi *****,

Thanks for reaching out!

I'm Joel, and I'll be happy to assist you here.

I'd like to let you know first, that the official C# Admin SDK doesn't support the Realtime Database nor Firestore yet. You can check the support here.

Now, you might be referring to the GOOGLE_APPLICATION_CREDENTIALS environment variable to authenticate your application with Firebase.

Firebase is oriented towards mobile applications mainly and Web applications also have their space. In order to manage different aspects of these applications, the Admin SDK came to light, but it is oriented to work on servers (to be used in admin apps.), and that's why identifying your admin app with Firebase is necessary; to accomplish project management tasks.

You can build web apps or mobile apps to make the most out of Firebase services. But unfortunately, complete support for C# isn't provided yet. The team is already working on this feature request, but for the moment it's ...[not] there yet.

Please let me know if you have more questions.

Cheers, Joel

As is documented here, and is mentioned in the support email, you need to use GOOGLE_APPLICATION_CREDENTIALS.

Firebase support is talking about the Firebase SDK, but you're using the Google Cloud library, which does support local authentication.

To make it work locally, you need to follow the auth documentation, which I'm assuming you already did.

Your friend, to make it work, will have to do the same steps with their service account, and then you'll have to update the permissions on your Firesotre (according to these docs) to give your friend's service account the right access.

There are additional authentication options, and all are compatible with the Google Cloud libraries, which you're using.
