Error: 'Package restore failed rolling back package change for' while running Scaffold-Dbcontext in Entity Framework Core 7.0.14

Question

Hello,

I'm working on a project using .NET Core 7 and encountering an issue when running Scaffold-DbContext with Entity Framework 7.0.14. The error message I'm getting is "there was an error running the selected code generator package restore failed rolling back package chanse for." I'm seeking guidance on resolving this issue in the context of .NET Core 7.

Versions I'm using:

• .NET Core 7
• Entity Framework 7.0.14
• Project GitHub link: GitHub Link

If anyone has encountered a similar problem or has suggestions on how to address this, I would greatly appreciate any help. Thank you.

I attempted to generate a DbContext using Scaffold-DbContext in Entity Framework Core 7.0.14 within my .NET Core 7 project. I expected the command to execute successfully and create the necessary DbContext based on my database schema. However, during the process, I encountered an error

There was an error running the selected code generator package restore failed rolling back package change for

Despite multiple attempts, I couldn't resolve this issue. Seeking advice on resolving this error in the context of .NET Core 7 and Entity Framework Core 7.0.14

 public class ApplicationDbContext : IdentityDbContext
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
        {
        }
        public DbSet<Category> Categories { get; set; }
        public DbSet<Product> Products { get; set; }
        public DbSet<ProductPrice> ProductPrices { get; set; }
        public DbSet<OrderDetail> OrderDetails { get; set; }
        public DbSet<OrderHeader> OrderHeaders { get; set; }

    }

Answer 1

There is no version 7.0.14. I updated the others to 7.0.11, but it still didn't work. But when I upgraded my project to .net 8, it worked but I started getting other errors. I need to make the project with .net7

Answer 2

Did you address this problem? I also have this problem and don't know how to address

Answer 3

I have resolved it by using .NET CLI described in the document. https://learn.microsoft.com/en-us/aspnet/core/security/authentication/scaffold-identity?view=aspnetcore-6.0&tabs=netcore-cli#scaffold-identity-into-a-razor-project-without-existing-authorization-1

For example, I'm using an existing db context

dotnet aspnet-codegenerator identity --dbContext MyDbContext

Please be noted that the target framework and version of all packages should be the same (6.x/7.x/8.x)

Answer 4

I'm using VS2022 (17.9.6) and just had the same issue.

I updated the NuGet packages.

I cleaned the solution

I cleaned the project

I did a rebuilt on the solution and how it's working again. Hope this might help someone else in future as all other solutions I tried didn't work for me
