Additional context When I try to re-install the ML.NET Model Builder 2022, it says this.

But when I go to extension list it does not show up there.

Maybe go check in VS installer to see if you can find model builder there?

It was installed on the machine and still is.

SS 1 (VS is up-to-date)

SS 2 (This looks suspicious: "Total space required 485 MB")

And it still does not appear in the new item list or is not created by VS 22 IDE for the Console App (C#)

I am also experiencing this issue.

@dansimon363 Can you try the following steps and let us know the results

• create an empty file with extension “.mbconfig” and see if you can double click and open it
• install model builder from gallery and see if it works

Thanks

Hi @LittleLittleCloud, thanks for your response. I created an empty file with the extension ".mbconfig" and this is what appeared:

I clicked OK and then this page appeared.

I was able to successfully train some data so it looks like this is a valid workaround for me. Thank you! 😃

In Extensions -> Manage Extensions, ML.NET Model Builder 2022 is not listed under Installed.

I can see it under Browse.

I get this message after clicking Install:

I originally installed the extension from here: https://marketplace.visualstudio.com/items?itemName=MLNET.ModelBuilder2022&WT.mc_id=dotnet-35129-website.

I tried using a console application that targets .NET Framework 4.7.2 and I don't see "Machine Learning Model (ML.NET)" item in the list. I also tried a different console application targeting .NET 8.0 as well and this produced the same behavior.

@dansimon363 Thanks for verifying the workaround. It means that the model builder is installed on your VS, it's just the new item dialog doesn't show .mbconfig item correctly.

We will try reproduce this error on our side and working on a fix for this bug.

[dansimon363]

You are welcome, sounds good and thank you.
