My intellisense for NuGet doesn\'t show up. Or maybe there is some kind of shortcut for it ?
I don't think the intellisense is what you expect, as in a dropdown with a list of available options.
From this page, it appears you have to hit tab in order to get command completion.
Not sure where you refer to intellisense. The answers above apply to the PowerShell console, which is tab completion.
If you refer to intellisense for the *.nuspec file, you only need to have the correct XSD and XmlNs declaration to get intellisense for the NuGet manifest xml file.
The NuSpec package might help you achieve this with ease.
Simply Install-Package NuSpec
