Visual Studio Error - Cannot find name 'Record'

Question

I am working on an ASP.NET project with c# in Visual Studio 2015 and I came across an error in the file index.d.ts. The error messages are Cannot find name 'Record' and Cannot find name 'undefined'.
I saw that would be some error related to Typescript, but I don’t know what exactly. Can I get a help? Thanks already.

Answer 1

Updates Typescript to a more up-to-date version.
