When using Paket from context menu, VS2017 becomes unresponsive

[fourpastmidnight]

Description

On more than one occasion, using the Install option in Visual Studio 2017 causes Visual Studio to become completely unresponsive, with the only alternative being left to force kill the VS process.

Repro steps

1. Open a solution which contains Paket references
2. Open one or more code files from a project containing a paket.references file.
3. Right click the paket.dependencies file and choose Install.

VS 2017 hangs. For example, see the git-tfs project here on GitHub.

Expected behavior

Visual Studio 2017 doesn't hang.

Actual behavior

Visual Studio 2017 hangs

Known workarounds

Don't open any project code files for projects containing a paket.references file when you need to perform any Paket operations on the solution.
