error TS5023:Build:Unknown compiler option ‘listemittedfiles’. Apparently, the problem was related to a strange option switch used by the Visual Studio 2015’s MSBuild task: , which has been introduced in TypeScript 2.0 and shouldn’t be used with earlier versions of TypeScript such as the one he was using to compile my project, which was 1.7.5.

error TS5023:Build:Unknown compiler option ‘listemittedfiles’. Apparently, the problem was related to a strange option switch used by the Visual Studio 2015’s MSBuild task:
When strictTemplates is true, Angular 9 and the Ivy compiler verify that hero is a valid model of type Hero, and that the properties on that model ( hero. id and hero. name) are also valid. "Angular 9's Ivy compiler and the strict template check finds errors that Angular 8 could not detect." Should We Use Strict Templates Now?
strictTemplates is a parameter for the angular compiler.
In your tsconfig.json: move the parameter inside angularCompilerOptions
"angularCompilerOptions": {
...,
"strictTemplates": true,
...
}
Angular >= 9 is necessary.
