Edited Issue: TypeScript: Add Existing as Link causes build errors [863]

Using the March DEV build.

Create two Node.js TypeScript projects in a single solution. In the first project add a new TypeScript file and create content. In the second project do Add Existing Item, navigate to the TypeScript file in the first project, and do Add As Link. When I do this I get 471 compile errors, all in node.d.ts. If I Add instead of Add As Link (which will make a local copy of the file) the compile errors go away.
