XAF 21.2.4 wizard creates a .Net 5.0 project.
To use migrations with EF Core the docs are here,
Initially I tried
PM> Install-Package Microsoft.EntityFrameworkCore.Tools
However that gave
Install-Package : NU1202: Package Microsoft.EntityFrameworkCore.Tools 6.0.1 is not compatible with net5.0 (.NETCoreApp,Version=v5.0). Package Microsoft.EntityFrameworkCore.Tools 6.0.1 supports: net6.0 (.NETCoreApp,Version=v6.0)
At line:1 char:1
+ Install-Package Microsoft.EntityFrameworkCore.Tools
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Install-Package], Exception
+ FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand
So I used Manage Packages For Solution to install the version 5
The latest version of 5 caused a build error. I found that I had to use version 5.0.0.0 of the tools to be compatible with the code generated by the wizard.
PM> Add-migration one
Caused
Your startup project ‘Dtg.Blazor.Server’ doesn’t reference Microsoft.EntityFrameworkCore.Design. This package is required for the Entity Framework Core Tools to work. Ensure your startup project is correct, install the package, and try again.
Thus I also added the tools to Blazor Server project and tried again.
This time I got
PM> add-migration one
Build started...
Build succeeded.

Looking at the code the Wizard generated I see this is expected.
