Description

Title: ABP CLI 10.5.0-rc.4 generates project with wrong EF Core Design dependency

Environment:

• ABP CLI: 10.5.0-rc.4
• .NET SDK: 10.0.301
• dotnet-ef: 10.0.9
• OS: Windows 11
• Database: SQL Server

Steps to reproduce:

1. Install ABP CLI 10.5.0-rc.4.

2. Create a new project using abp new.

3. Run:

   dotnet list package --include-transitive

4. Observe that:

   Microsoft.EntityFrameworkCore.Design 8.0.0
   

   is resolved transitively even though the project targets .NET 10 and uses EF Core 10 packages.

Symptoms:

• dotnet ef migrations list throws:

  System.TypeLoadException:
  Method 'Identifier' in type
  'Microsoft.EntityFrameworkCore.Design.Internal.CSharpHelper'
  from assembly 'Microsoft.EntityFrameworkCore.Design, Version=8.0.0.0'
  does not have an implementation.
  

• DbMigrator fails during seeding with:

  Invalid object name 'AbpSettings'
  

Workaround:
Adding the package explicitly fixes the issue:

dotnet add package Microsoft.EntityFrameworkCore.Design --version 10.0.7
dotnet restore

After adding the explicit reference:

• dotnet ef migrations list works correctly.
• DbMigrator completes successfully.

This isn't really ABP-specific — it comes from a packaging change in Microsoft.EntityFrameworkCore.Tools. Starting with 10.0.6, the Tools package only declared a net8.0 dependency group with Microsoft.EntityFrameworkCore.Design >= 8.0.0. On a net10 project there's no matching group, so NuGet falls back to that one and resolves Design down to 8.0.0 — and the 8.0.0 Design assembly is exactly what throws the TypeLoadException you hit. The EF team tracked it in dotnet/efcore#38124 and fixed it in dotnet/efcore#38210, shipped in 10.0.9 (Tools now has proper net8/net9/net10 groups).

For your existing project, bump Microsoft.EntityFrameworkCore.Tools to 10.0.9 and restore — Design resolves back to 10.0.9 and both dotnet ef and DbMigrator work again. Your explicit Design 10.0.7 reference does the same thing, so either way is fine.

One more thing: the project was generated with the old abp CLI, which is legacy now. New projects are created with the new ABP CLI (Volo.Abp.Studio.Cli), and its templates already reference Microsoft.EntityFrameworkCore.Design directly, so they don't run into this at all:

dotnet tool install -g Volo.Abp.Studio.Cli
