How to fix "The project doesn't know how to run the profile ConsoleREPL" in Visual Studio?

Steve S 11

I'm trying out PowerFx using the instructions on this page: https://powerapps.microsoft.com/en-us/blog/power-fx-open-source-now-available/

I installed the community version of Visual Studio 2022 on Windows 10. I cloned the repository for PowerFX Host Samples and built the ConsoleREPL solution. Worked fine. When I select "Start Debugging" I get a popup that says "The project doesn't know how to run the profile ConsoleREPL".

Please advise how to fix. I'm an experienced developer on other platforms, but not on Windows and have never used Visual Studio.

I've got the same issue. I'm trying to process an equation called "collatz conjecture" but I get the same error message. I've tried cutting out the code except for literally just a Console.ReadLine() but I still get the error. so I know it's not my code. if there is a fix someone let me know.

I'm using version Microsoft Visual Studio Community 2022 Version 17.5.3 and have the same bug: "This project doesn't know how to run the profile WSL and command WSL2." I tried Installer Repair and Modify and so on. The only method that works is to recreate Console App. . But after closing and opening solution bug returned. Please let me know if it can be fixed

The "project doesn't know how to run the profile..." error appears to be related to the Development Tools for .NET option in the .Net desktop development installation of Visual Studio 2022. It should be possible to resolve the problem by modifying the VS install to add this component. I'm not sure what else this component is affecting so it seems like MS might need to promote it from "optional" to "included".

This is not working

The following shows the launch settings I have for a Roslyn Generator project and using Visual Studio 2022.

You can take a look at the project here on github.

I have added the workloads as well as follows.

This didn't work for me, but updating Visual Studio to 17.4.3 after installing Development tools for .NET did fix it.

I had the same error message but the unknown component was MSIX in WinUI 3. Well, MSIX is VS development so I added that component. That didn't do it completely. I had installed Windows App SDK previously. I went into the VS Installer and it wasn't checked under individual components so I checked that. Then I had to change Configuration Manager so Deploy was checked. Then it worked. Hope it helps someone.

The tooling on WinUI is a bit raw right now. Hopefully, it gets fixed soon. Love it other than that.

Hi @Steve S ,

Welcome to Microsoft Q&A forum.

Sounds like a potential issue, if you try to repair Visual Studio, will Visual Studio 2022 work?(Visual Studio Installer > find Visual Studio 2022 > click More > click Repair > wait for VS complete repairing)

Feel free to let me know the result.

Best Regards,
Tianyu

I repaired VS as you suggested. There is no change in the behavior when I tried to run ConsoleREPL

Hi @Steve S , I noticed that this issue or similar issue is/should be a potential issue, for instance: The project doesn’t know how to run the profile… So, please try to update VS 2022 to the latest version and clone the project to another directory then try to rebuild and run the project again.

If this issue still persists, I suggest you directly report it on Developer Community.

Repairing and rebooting resolved this issue. I would check both.

I changed my account to administrator and created a new app. Now it opens the console.

I thought this was in "Account Settings" but it's not.
Would you please elaborate on where exactly we need to go to change the account to Administrator?
Thanks in advance

I did that to no avail :(
I thought I had included the .NET Desktop Development workload during the installation, but I am not totally sure. How can I confirm it?
The ironic part is that I am getting better results from the VScode app that was installed as part of Unity.
