How to fix the problems with the package manager console in Visual Studio 2017

So – you’re getting the following problem

The following error occurred while loading the extended type data file: Microsoft.PowerShell.Core, C:\Windows\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(3763) : Error in type “System.Management.Automation.FormatViewDefinition”: Exception: The getter method should be public, non void, static, and have one parameter of type PSObject.

For some reason this just started happening after the last Visual Studio 2017 update

Update – 5/29/2018 – make sure to leave VS Code open while you open Visual Studio 2017 – the problem does recur after every restart for some reason.

First – locate devenv.exe.config in the C:\Users\WarHorse\AppData\Local\Microsoft\VisualStudio\15.0_YOURIDENTIFIER directory

Open that file in VS Code

paste the following in with the other dependent assemblies
