Visual Studio not opening TypeScript *.ts files?

Question

When I try to open a TypeScript file, my cursor goes busy for a bit, then nothing happens; the code window doesn't open.

What could be the problem?

Answer 1

I'd installed the Qt Visual Studio Tools extension for Visual Studio 2017. This associated *.ts files with the QT Linguist file format and editor.

To fix the problem, I right-clicked a *.ts file, navigated to the Open With dialog, and defaulted TypeScriptEditor as the program to open the file.
