<panel title="Summary">

As they say in the advertisement, having Nuget manage your Packages and keep them up to date is practically seamless and automatic.

In reality...it's not.

But Nuget remains so much better than the older options that one has to grit one's teeth and bear with it.

## Background ##



## Process ##

### Via Package Manager Console ###

Use the powershell commands to do the updates:

Update all packages in solutiuons

    Update-Package

Update a single package

    Update-Package Elmah

Update a single project

    Update-Package -Project MyProject

Update a single project, with version.

    install-package Nab.wdms.PM.M01.Infrastructure.Data.Seeding XAct.Data.Db.EF -Version 0.0.650

> Watch out: it might be versioned...but it refers to is not...so XAct.Core (higher version) might get called in...


## Background ##

According to: http://blog.davidebbo.com/2011/05/thoughts-on-installing-and-updating.html what happens is more than just a copy/update of the project files.

* Add references to assemblies contained in the package
* Add references to framework assemblies in the GAC
* Add content files to an app (e.g. JavaScript files, code files, …)
* Add assembly binding redirects to deal with version incompatibilities
* Perform config transformations, typically to add settings related to the package
* Bring in tools that can then be run from Package Manager Console
* Run PowerShell scripts which can do arbitrary things by automating the DTE object model

>It explains why the Package Manager Console has a $dte reference -- it would be very hard to do the above from outside Visual Studio.
