Running F# Hello World from VS Code

Question

I ran the canonical F# Hello World program by

dotnet run

It works. Now, I want to run it from VS Code, pushing F5 from the editor window showing Program.fs . In launch.json I have

"program": "${workspaceFolder}/HelloWorld/bin/Debug/netcoreapp3.1/HelloWorld.dll",

where HelloWorld is the project directory which is a child of the directory where the solution file resides. This file exists.

Upon hitting F5 I get

Could not find the task 'build'.

How can I configure VS Code to run my F# program with F5?

A search for

tasks.json f#

revealed

and that answers my question: when the dialog box with the

Could not find the task 'build'.

message pops up, I should choose

Configure Task

and in the pop down window

Create tasks.json file from template

and then the

.NET Core

template. Afterwards, F5 works to build and run the F# program.
