pkg version must be specified as below, then it works.

dotnet add package Microsoft.EntityFrameworkCore.Sqlite --version 2.2.6
dotnet add package Microsoft.VisualStudio.Web.CodeGeneration.Design --version 2.2.3
dotnet add package Microsoft.EntityFrameworkCore.Design --version 2.2.6

Hello, @junk123321

Thank you for your feedback.

We are actively reviewing your comments and will get back to you soon.

Kind regards,

Hi team,
In the last comment the user makes a suggestion on the code
best

[guardrex]

Hi @CeciAc!

Looks like a tooling bug to me because the version has been optional. Either that or the 🧀 moved and they changed the command syntax. Perhaps, it should be opened as an engineering issue before changing anything that we have. We have ~20 instances of the command around the docs without specifying a version. cc: @Rick-Anderson If so, we'd ask here 👉 https://github.com/NuGet/Home/issues

[guardrex]

Side question for you @junk123321 ... you're sure that you don't have a global.json file (or nuget.config) around in the directory tree at or above the project? If so, that might foul the package discovery.

btw-- What SDK version are you using?

[guardrex]

One more thing comes to mind @junk123321 ... you might be in a broken package cache state. Try executing this command to nuke the package cache ...

dotnet nuget locals --clear all

... then try the command from the topic again (without the version) and see if it works.

[Rick-Anderson]

This can fail for several reason as @guardrex mentions. This is not a doc bug. Given we have thousands of customers reporting success on this, it's almost a certainty this is not a bug.

Another two commands have similar problems.
dotnet add package Microsoft.VisualStudio.Web.CodeGeneration.Design
dotnet add package Microsoft.EntityFrameworkCore.Design

Follow the suggestions of @guardrex and do some searching on SO to figure out what you've done wrong.
