How do I restart the Task Runner within visual studio?

I have a gulp task to convert my .less file to css. This works fine until there is a syntax error in the less file. This causes gulp to crash and the Task Runner Explorer stops and I can't restart it. I have to unload/reload the project to change a syntax error.

Any ideas how to restart the Task Runner Explorer?

Tasks can be started and restarted any time. Non-terminating tasks, like "watch" tasks, can be started multiple times and will run in parallel, unless terminated. One way to start a task is to double click on it in the list. There is also a "run" command in the context menu.

Terminating a task

I had this same question today, but for other reasons. Apparently closing the associated console window terminates the task.

Task Runner prompt to terminate a process

I remember in some older version of Visual Studio I had to open Task Runner Explorer manually, otherwise the tasks would not start.

Regarding syntax errors

To save yourself from the trouble of restarting a task, add some type of error handling. There are probably more solutions to this, but I used this one. Here's a shorter version:

const gulp = require('gulp');
const plumber = require('gulp-plumber');
const lessCompiler = require('gulp-less');

const lessFiles = 'Styles/**/*.less';
const compileLessTaskName = 'compile-Less';
gulp.task(compileLessTaskName, function () {
  return gulp.src(lessFiles)
    // Calling plumber at the start of the pipeline. In case of error, this stops
    // the task without killing the whole process.
    .pipe(plumber(function (error) {
      console.log(error.message);
      this.emit('end');
    }))
    .pipe(lessCompiler())
    .pipe(gulp.dest('wwwroot/css'));
});

gulp.task('watch', function (asyncCallback) {
    gulp.watch(lessFiles, [compileLessTaskName]);
    asyncCallback();
});
