Test is a console application, target framework is .net core 3.1, and I have added PublishSingleFile to the project file, but I can't find the publish button in the context menu.

Answer 1

Hi @Shingo Oscar

Thank you for reporting it in Microsoft Q&A.

I created a C# console project to test, the ‘Publish’ button is available.

You can try to re-install C# workloads, repair and update Visual Studio.

You can also run devenv /safemode command to start Visual Studio without any extensions, you can refer to this document.

Sincerely,
Peng

I solved this by updating the .vbproj file. I had to add the Project Type Guids to the "PropertyGroup" tag. <ProjectTypeGuids>{349c5851-65df-11da-9384-00065b846f21};{F184B08F-C81C-45F6-A57F-5ABD9991F28F}</ProjectTypeGuids>. In this case GUID 349c5851-65df-11da-9384-00065b846f21 is for ASP.NET MVC 5 and F184B08F-C81C-45F6-A57F-5ABD9991F28F for VB.NET. Have a look at GitHub List of GUIDS. Multiple Guids can be added, separated by a semicolon.
