Entity Framework Core | dotnet ef dbcontext scaffold | Could not load assembly of project

I want to scaffold a SQL Server and output to a project.

I have a solution with 2 projects:

  • Project 1: "Scaffolder" .NET 6.0
  • Project 2: "Scaffolded" .NET Standard 2.1

They both have these dependencies

  • Microsoft.EntityFrameworkCore 5.0.0
  • Microsoft.EntityFrameworkCore.Design 5.0.0
  • Microsoft.EntityFrameworkCore.SqlServer 5.0.0

I want the scaffolded data in project Scaffolded.

In the solution folder I run this command:

dotnet ef dbcontext scaffold "<MyConnectionString>" 
       Microsoft.EntityFrameworkCore.SqlServer 
       --startup-project Scaffolder --project Scaffolded --output-dir Models --force

I get this output:

Build started...
Build succeeded.

Could not load assembly 'Scaffolded'. Ensure it is referenced by the startup project 'Scaffolder'

Why do I get this error?

I run Entity Framework Core .NET Command-line Tools 5.0.2

Solution

  • Just use EF Core Power Tools - but upgrade to EF Core 6, EF Core 5 is no longer supported.
