Visual Studio 2019: Not showing Typescript Intellisence

1.For now, the default Typescript SDK is 3.6, so if you have early SDK versions like 2.x, I suggest you install corresponding TypeScript SDK extensions here. And according to this document:

If your TypeScript version is less than 3.1, please Disable dedicated syntax process under Tools > Options > Text Editor > JavaScript/TypeScript > Language Service and restart Visual Studio (from the same command prompt).

You can follow it if the TS version you use is less than 3.1.

2.Or you can try updating to TS 3.6 which is default in VS2019.

Note: Please make sure you're opening the Solution/Project instead of single typescript file.
