Azure deployment error when trying to install dotnet-ef

Question

I am having trouble deploying my website to Azure due to an error with installing dotnet-ef. I have tried various versions using Nuget and the console, but I'm still unable to upload my app to the cloud. I'm following this tutorial https://www.youtube.com/watch?v=lL2y6AjSRss&list=PL5amK2cLXLjSnwJI5pYr6G_NaOvrN_dJP&index=1&t=551s&ab_channel=EvanGudmestad. How can I fix this issue so I can publish my website on Azure with database functionality?

Answer 1

The error is related to dotnet ef tools a set of extensions for CLI to do database stuff related to Entity Framework.

Every time you want to create a migration or update a database for example, you need to run dotnet ef ... command.

dotnet ef migrations add YOUR_MIGRATION_NAME
dotnet ef database update

These commands can be run by installing dotnet ef tools and you can do this by running this command on your terminal:

dotnet tool install --global dotnet-ef

If you already have EF Tools installed and want to update it, you can run the following command:

dotnet tool update --global dotnet-ef

And to check your EF Tools version you can run this:

dotnet tool update --global dotnet-ef

Given this context, you can do the following:

1. Verify your EF Tools Version
2. Install or update your EF Tools
3. Try your deployment again

In additional, you need the following packages added to your project:

dotnet add package Microsoft.EntityFrameworkCore.Design
