Visual Studio 2019 TypeScript build erorrs after adding site.ts and then nuget package Microsoft.TypeScript.MSBuild

Question

In Visual Studio 2019 (v16.11.5) I added a site.ts file and some ts code. VS prompted me to install the nuget package Microsoft.TypeScript.MSBuild, which I did. Now on site.ts save site.js is produced just fine, however, now VS won't build the solution and produce a number of TS errors (see screenshot).

When I remove Microsoft.TypeScript.MSBuild the solution builds, but site.ts does not compile on save.

Any idea about what I'm missing (package/setting/other)?

I have a gulpfile.js which I guess could also handle the ts compilation.

Following https://docs.microsoft.com/en-us/visualstudio/javascript/compile-typescript-code-nuget?view=vs-2019 turns out I was missing a tsconfig.json file in project root.

I added this to the file:

{
  "compilerOptions": {
    "noImplicitAny": false,
    "noEmitOnError": true,
    "removeComments": false,
    "sourceMap": true,
    "target": "es5"
  },
  "exclude": [
    "node_modules",
    "wwwroot"
  ],
  "include": [
    "Scripts/site.ts"
  ]
}
