Get-Package does not work with NuGet, but works when called by Install-Package ?

[Jaykul]

For example, note in this trace that the second call to Install-Package correctly detects the package is already installed, but there's no way for me to get the information from the installed package (e.g. what source it came from), and the output of Install-Package doesn't even have the install location.

This is wrong ...

PS> $Package = @{ 
    Name = "Newtonsoft.Json"
    ProviderName = "NuGet"
    Source = "https://www.nuget.org/api/v2"
}

PS> $Options = @{
    Destination = $PWD
    ExcludeVersion = $true
    PackageSaveMode = "nuspec"
    Force = $true
    Verbose = $true
}

PS> Install-Package @Package @Options
VERBOSE: NuGet: Installing 'Newtonsoft.Json 7.0.1'.
VERBOSE: NuGet: Successfully installed 'Newtonsoft.Json 7.0.1'.

Hi Jay, Get-Package for nuget requires a destination parameter. That's why it didn't work. Have you tried Get-Package -ProviderName nuget -Destination ?

[Jaykul]

I definitely included the same Destination.

If you look at my sample code, you'll see I provided it the exact same parameter hashtable as I did to Install-Package (except that I had to remove the Source parameter).

Hi jay, sorry for overlooking that. We actually had a fix for this issue (just hasn't been released yet). Also, in the last community meeting, we have communicated to the community that we are rewriting our own nuget package provider so that it will run on nano server. We remove the PackageSaveMode option from the new nuget provider, will this affect your existing scripts?
