Including "Microsoft.TypeScript.MSBuild" in a project breaks Typescript compile on save

TypeScript Version: 3.2.0-dev.201xxxxx
Tested, bug still present.

Descriptions and Steps to reproduce

Including the latest version of the Nuget package "Microsoft.TypeScript.MSBuild" in a project breaks Typescript compile on save. However, it is required to have your Typescript files generated during a dotnet publish.

Reproduced in Visual Studio Professional 2017, Version 15.8.6.

1. Create new "ASP.NET Core Web Application" project in Visual Studio 2017.
2. Choose "Web Application (Model-View-Controller). Do not configure for HTTPS.
3. In the wwwroot directory, create a new .tsx file - click wwwroot directory | add | new item | Web | Typescript JSX file.
4. The properties of the new file show "Package Action" is "TypeScriptCompile".
5. Enter some simple TypeScript in the new file, for example "var x: number = 5;". On save, the file is automatically compiled.

---

6. Perform a "dotnet publish" on the command line in the root directory of the project. The .tsx does not get compiled as part of the publish.

---

7. Add the line "" to an ItemGroup in the .csproj of the project.
8. The properties of the .tsx file added earlier no longer show a "Package Action".
9. Edit the .tsx file - it is no longer compiled on save. It is still compiled though when you build the project.

---

10. Perform a "dotnet publish" on the command line in the root directory of the project. The .tsx now does get compiled as part of the publish.

// A *self-contained* demonstration of the problem follows...
// Test this by running `tsc` on the command-line, rather than through another build tool such as Gulp, Webpack, etc.

Expected behavior:
Including the Microsoft.TypeScript.MSBuild package should not break compile on save.

Actual behavior:
Including the Microsoft.TypeScript.MSBuild package breaks compile on save.

Currently, compile on save in VS requires a matching version of the TypeScript language service to be installed on the machine. Would you try installing it from https://www.microsoft.com/en-ca/download/details.aspx?id=55258 and see if that fixes the issue?

Closing this as my understanding is this is working as intended.
