NativeScript CLI 7.0. and Angular Compiler requires different TypeScript versions

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 7.0.6
• Cross-platform modules: v7.0.0
• Android Runtime: v7.0.0
• iOS Runtime: v7.0.0
• Plugin(s):

Describe the bug
While updating / migrating my project to v7 typescript will get set to version 3.9.7 to be complaint for v7.
This leads to an issue when starting the application.

ERROR in The Angular Compiler requires TypeScript >=3.4.0 and <3.6.0 but 3.9.7 was found instead.

When now downgrading "typescript": "3.5.3", we will receive an error message that the application is not compatible anymore.

splash34$ tns debug android
The current application is not compatible with NativeScript CLI 7.0.

Run 'ns migrate' to migrate your project to NativeScript 7.

Alternatively you may try running it with '--force' to skip this check.

To Reproduce
Setup project with following dependencies:

"dependencies": {
    "@angular/animations": "10.1.0",
    "@angular/common": "10.1.0",
    "@angular/compiler": "10.1.0",
    "@angular/core": "10.1.0",
    "@angular/forms": "10.1.0",
    "@angular/http": "^7.2.16",

  }

Expected behavior
Start application after upgrade with emulators.

Commencez par les versions des dépendances dans package.json et reproduisez l’échec avec tns debug android. Examinez la vérification de compatibilité de CLI et le chemin ns migrate afin de déterminer comment NativeScript CLI 7.0.6 gère les exigences liées à Angular Compiler et TypeScript ; la tâche est considérée comme terminée lorsqu’un projet correctement migré peut démarrer sans erreurs de versions en conflit.
