How to use Type Script 1.8 in Visual Studio 2017 for legacy project

Question

I have recently installed visual studio 2017 and tried to run my project in it. It is causing TypeScript error. I think VS 2017 is using Typescript 2.1.5 but my application was writted for TypeScript 1.8.

How can I make VS 17 use TypeScript 1.8. I already have VS 2015 and the solution is working fine on it. But I really want to use 2017(without making changes to code)

The odd thing is: The TypeScript version mentioned in .csproj is 1.8

<TypeScriptToolsVersion>1.8</TypeScriptToolsVersion>

But if I edit the .csproj the TypeScriptToolsVersion to something else and then back to 1.8, the solution compiles properly. However, after consecutive compiles, the TypeScript resurfaces.

I noticed the compile errors disappeared when you "force" a downgrade of TypeScript by applying nuget package Microsoft.TypeScript.MSBuild.1.8.11.

That way the solution/project seems to use the package version instead of the built in version.
