Microsoft.TypeScript.MSBuild 2.0.3 - Painful when switching branches because it says the file is locked

[demyte]

TypeScript MSBuild Version: 2.0.3

Expected behavior:
The package files are not locked by VS or MSBuild so that when switching branches to another branch without this package or with a different version of this package we dont have to close VS to get a clean repository.

Actual behavior:
When we switch branches from a branch with this in place to one without it or with another version, the files are locked and we have to close Visual Studio down to release the locks.

I found an obscure way of solving this, using the environment variable MSBUILDDISABLENODEREUSE=1 to stop the MSBUILD.exe tasks being left open by VS.
