vscode does does not respect tsconfig.json configuration for ts files

[hadson172]

• VSCode Version: 1.47.2
• OS Version: Windows 10

Steps to Reproduce:

1. Open empty folder
2. Create .ts file
3. "Go to project configuration"
4. Configure tsconfig.json file
5. Go to back to the .ts file, repeat step 3 (should navigate to the file, but instead it shows popup :
   

Second approach to the same problem:

1. Open empty folder

2. Create two files: first.js and second.ts

3. Type const a = 1000 in first.js and const a = 2134123 in second.ts (the values, modifier does not matter)

4. Configure tsconfig.json with allowedJs: false
   

5. There shoud not be re-declaration error message in ts but it is:
   

Third example of the same problem:

1. Create two files - first.ts and second.ts
2. Change property in tsconfig.json to modules: "none"
3. VScode helps with imports when it should not

So why tsconfig.json is not respected?

Does this issue occur when all extensions are disabled?: Yes/No

The solution for that is to restart once or few times vscode. Then it points to proper tsconfig.json file. In case of presence of jsconfig.json and tsconfig.json only tsconfig.json is taken into consideration. VSC docs does not state anything about required restart after creation of file :/

Edit: Looks like that in case of modules, still getting re-declaration error message (even if vs code point to right file):

This works for me on VS Code insiders

Did you save the tsconfigs? It won't actually be written to disk or used by typescript until you save it.

Created new project and configuration file i am getting:

As you can see on the screenshot everything is saved.
After restart: (as you can see now it recognized method flatMap from esNext (so it read configuration) but it required restart

Modules:
As you can see i see in the configuration file modules enabled. So there should not be duplication error message but there is: (and it reads configuration properly)

Here's what I see in VS Code insiders on windows (there is a ~2sec delay after saving the config file before the error goes away):

The second error is expected. If your files does not use any imports or exports, then it is treated as being part of the global scope

Still having the issue. Is there any way to debug this problem or see detailed logs?
About second case. If all files are included agree. But if i include only one of the files in tsconfig.json and the other one is excluded i should not be getting collision errors this is my understanding at least.

Edit: Looks like that if i will create project + project configuration in one visual studio code run(iteration) there is a lot of problem with properly reading and refreshing content of configuration file. Like target version, files/included excluded etc. After one restart everthing works properly.

Problem persists. Opening a folder with VScode, a .ts-file delivers 191 errors, after first edits jumps to 591 errors without any changes to the code. Seems tsconfig is not used anymore after first edits.

TSconfig.json seems to be ok:

{
  "compilerOptions":
  {
     "outDir": "./dist",
     "allowJs": true,
     "checkJs": true,
     "module": "ES2015",
     "target": "ES2015"
  },
  "exclude": ["node_modules", "**/node_modules/*", "dist"]
}

TSC is not installed !
