I have a created a very, very simple BLAZOR app for testing purposes. Its Visual Studio 2022 with .Net9.0. With ADD> "Docker support" I let Visual Studio 2022 create the DOCKER file. When I try to run it, I get: "The project doesn't know how to run the profile with name 'Container [Dockerfile] and command 'Docker'". My first guess was that DOCKER extension is not added. Hence I went to EXTENSIONS > BROWSE and searched DOCKER. This resulted in some "random" results like "Captain Docker", which I installed. The result is the same though. I had DOCKER Desktop running while I was doing all these. In Windows 10, I have WSL2. Please help.

I found the answer to this in: https://learn.microsoft/en-us/answers/questions/1343108/nuget-error-nu1101. Follow the answer provided by: Tianyu Sun-MSFT. The origin of the problem comes from "NuGet Error NU1101". The solution states: you need to add another valid package source for VS to find the specific packages.

Please click Tools > NuGet Package Manager > Package Manager Settings > Package Sources > check if nuget. package source has been added. If it hasn’t been added, please click the “Add” button on top right corner > change the Name to nuget. and the Source to https://api.nuget./v3/index.json > click Update > click OK, then rebuild your project.

Thank you all.
