Uninstall and Install JQuery.UI.Combined package is so slow in a project with AutoT4MVC

[Tim Lovell-Smith]

This may be a AutoT4MVC bug, or nuget bug, either way it would be great to get it fixed.

This is NuGet 2.5, VS 2012 Update 3 2013, and AutoT4MVC 1.0

Basically It seems like the policy of running on item added/removed/saved is having some unwanted consequences when the project file is having many items added/removed at once by nuget.

When I do Uninstall-Package of JQuery.UI.Combined, see that it takes a looong, long time, attach debugger and break at random I see a call stack with:

Hey,

Can you please try updating to the latest version of AutoT4MVC (1.2.0). You should be able to update directly from the Extension Manager.

This exact situation used to be a big problem, but in the last release I added throttling of the events so it will wait to start running the template until a second after the last event (item added/removed) has fired and will only run once per burst of files.

Cheers
