When the `ts.Project` creates the language service plugin (in this case, the Angular Language Service), it sets the project's language service to the new language service returned by the plugin create: https://sourcegraph.com/github.com/microsoft/TypeScript@b12af0fa2bbd4b015e59adcfb49988cea7f919a1/-/blob/src/server/project.ts?L2035-2044 The project may be reloaded in response to various events, such as a change to the tsconfig file, which then recreates the plugin. When this happens, the language service that gets passed to the plugin `create` function will not be the typescript language service, but rather the previous instance of the new language service returned by the last call to `create`. This commit ensures that subsequent calls to `create` for the `NgLanguageService` plugin for a project after the first call are able to retrieve and hold on to the _TypeScript_ language service. fixes https://github.com/angular/vscode-ng-language-service/issues/1923 PR Close #51912
