We have an internal NuGet repository for Our class Libraries. I've created a package MyPackage Version 1.0.0.0 which had a bug, so I pushed a New Version (or revision) of the package, 1.0.0.1.
Now, when I create a New Project and use the Manage NuGet Packages dialog, I get the latest Version (1.0.0.1) when I install the package. However, when I use the Package Manager Console for another New Project and type Install-Package MyPackage, I get Version 1.0.0.0 by default.
Why does this happen? I can't find anything in the NuGet documentation explaining why this happens, so it seems to be a bug in NuGet.exe.
Try running the Update-Package command.
The package is probably "cached" locally, and when you use the "Install", it only gets the cached version.
You can also verify this by going to:
(windows)
C:\Users\~MyUserName~\AppData\Local\NuGet\Cache\
OR (linux)
/Users/MyUserName/.nuget/packages/
(Replace ~MyUserName~ of course)
and deleting the package from there...then "Install".
(The idea being, if its not in the cache, it'll go back to the server to get it)
For information if anyone runs across this issue, it was a bug in 2.7 that has been fixed as of 2.8. Details at: https://nuget.codeplex.com/workitem/3684
Upgrading your client to 2.8 will fix the issue.

Intro
I am trying to create a project from the cloud using "UaaS.cmd".
I run it, fill the url and namespace and it start working. Then in the middle of the process I get the error:
Installing UmbracoCms.Core
The 'UmbracoCms.Core 7.6.5' package requires NuGet client version '3.4.4' or above, but the current NuGet version is '2.8.1.0'.
at NuGet.PackageWalker.CheckPackageMinClientVersion(IPackage package)
at NuGet.PackageWalker.Walk(IPackage package)
at NuGet.InstallWalker.ResolveOperations(IPackage package)
at NuGet.ProjectManager.Execute(IPackage package, IPackageOperationResolver resolver)
at Waasp.PackageInstaller.InstallPackage(String packageId, SemanticVersion version, String projectPath, String targetFolder)
But I have VS 2015 and VS 2017 installed. My Vs 2015 says that I have nuget version 3.5 installed and vs 2017 says that I have nuget v4.2.
What have I tried
I ran nuget in my cmd, but it was not a recognized so I've downloaded the latest version and have added it to my environment, so when I run cmd, go to the folder where I have my uaas.cmd file and type
nuget update -self
It tells me that I have nuget 4.2 and it is up to date. But when I try the uaas.cmd, the same error happens
I don't understand! where does it find 2.8.1.0?! why doesn't it take 4.2?
P.S: I also wrote on Umbraco forum, but I guess it is more related to the nuget client than umbraco
I wrote my question on our Umbraco too and it appeared to be their error :)
In case anyone ended up in the same situation as me:
This is the answer from Sebastiaan:
link to the topic
The problem is that UaaS.cmd does run nuget 2.8.1 in it (it's ILmerged into the waasp.exe it download).
I'm working on getting it updated but the v4 version of nuget.exe is missing some critical methods that we need to create the list of dependencies. So I'm looking into doing some trickery. Anyway, for now, just go into the .Core project and install Newtonsoft.Json and System.Threading.Tasks.Dataflow and then you should be fine!
Is it possible to use Cake to always get the latest version of a specific NuGet package? I know NuGet itself only allows you to set that at the base Nuget.config level. There are some internal packages that we would like to always get the latest version of (some of our database entities), while other internal packages we don't want to force a latest (our extensions package, for example). Right now we have to go through and manually update projects that rely on those packages, and I would like to automate those "always get latest" at build.
I don't see anything using any of the NuGet add-ins, but I am new to Cake so I'm hoping I am just missing something.
Has anyone had any luck using Cake to always retrieve the latest version on the feed for specific named packages, and just use the current packages.config version for the rest?
The short answer is that you can do anything that you want.
Cake out of the box will attempt to adopt established best principles for reproducible builds.
With the preprocessor directive, you could simply omit the version information, and Cake/NuGet will fetch the latest version. However, once downloaded to the tools folder, Cake/NuGet will not fetch it again. What you could do is add a custom step in your bootstrapper to clear the tools folder each time before build, and then the latest version will be downloaded each time.
Note: This is NOT a recommended approach, but rather something custom for your setup.
I installed paket from nuget in Nuget Package Manager Console with:
Install-Package paket
I then tried to run paket convert-from-nuget. It stalled out on a user prompt (it wouldn't let me type into the package manager console). My next thought was to run it from command line, but how to do so is not documented.
Just putting paket convert-from-nuget into a standard dev command prompt results in an error saying "paket" is not recognized.
How do I run paket from the command line or powershell, and how do you specify which solution to work against?
The way to setup paket in your repository is as follow:
1 Download a release of paket.bootstrapper.exe
This is a lightweight utility which obtains and updates paket.exe, pick stable release from official release page:
https://github.com/fsprojects/Paket/releases
2 create a .paket folder
md .paket
3 put the downloaded bootstrapper in this folder and invoke it
cd .paket
paket.bootstrapper
now you have an up-to-date paket.exe ready to ease your handling of dependencies.
4 convert from nuget
cd ..
.paket\paket convert-from-nuget
Please checkout the https://github.com/fsprojects/Paket.VisualStudio also for Visual Studio plugin to help you authoring paket.dependencies and paket.references file
Please also join https://gitter.im/fsprojects/Paket if you have any questions.
The Chocolatey package modifies the PSModulePath envivornment variable. I've observed that sometimes that modification isn't picked up until the system is restarted (or at least not until the user logs out and back in again). In the meantime, you can import the module using:
Import-Module <path-to-packages>\Paket.PowerShell\Paket.PowerShell.psd1
The packages path is usually something like C:\Chocolatey\lib. OTOH, re-reading your question, are you referring to the Nuget inside of Visual Studio? If so, that downloads from NuGet.org and that pkg puts paket.exe in $(SolutionDir)\packages\Pakget.1.18.5\tools\paket.exe. Your version number may varying.
Unfortunately the fact that PowerShell V5 introduces Install-Package (which downloads from Chocolatey by default) is going to get a little confusing vis-a-vie the NuGet Package Manager Console's Install-Package in Visual Studio.
VS 2013 fails to restore a package - the package contents are not materialized - although VS/nuget appears to think that it did restore the package successfully.
If I manually uninstall and re-install the same version of that package, it works as it should.
A bare-bones repro can be downloaded as a zip. This repro has a
single solution with a
single project with a
single file, "packages.config", specifying a
single package, "breeze.edmbuilder -version 1.0.4", containing a single file, edmbuilder.cs
single folder, "App_Start", contains nothing but
the .csproj says it should have "edmbuilder.cs" which is ok because
it WILL have "edmbuilder.cs" when the package is restored.
When I build, VS reports that "edmbuilder.cs" is missing ... and indeed it is missing.
However, the package was downloaded; I know this because the build produces a "packages" folder that contains "Breeze.EdmBuilder.1.0.4" wherein I see that "edmbuilder.cs" is present and in the right place.
When I issue the command install-package breeze.edmbuilder -version 1.0.4, nuget reports
'Breeze.EdmBuilder 1.0.4' already installed. NugetRestoreFail already has a reference to 'Breeze.EdmBuilder 1.0.4'.
There is nothing wrong with this package AFAIK. For when I uninstall-package breeze.edmbuilder and then reinstall with install-package breeze.edmbuilder -version 1.0.4, the install works and the missing edmbuilder.cs appears in the "App_Start" folder where it belongs.
The failure is repeatable in place.
close the solution
delete edmbuilder.cs from "App_Start"
delete the "packages" folder
optionally delete the .suo and bin and obj directories
re-open the solution and re-build
You'll get the same failing behavior ... and the same ability to manually uninstall and reinstall.
FWIW, removing the reference to edmbuilder.cs from the .csproj has no effect.
No matter what I do, I have to manually uninstall and re-install the package.
WTF!
p.s.: I am using VS 2013 Update 2 RC. I doubt that the "RC" matters as this problem came to my attention from a customer. You never know.
p.p.s: This is not about the build failing and I don't care that this solution would never run. What you see here is a stripped down version of a real app that would have worked. The only question is "why no restored file?"
Package Restore is NOT the same as installing a package. What you are seeing is by design. It simply downloads any missing packages in the packages folder. No more. No less.
Package Restore was added so you wouldn't need to commit the packages folder to source control.
It is expected that you would install a package then commit the changes made to your project files as well as any files that may have been added like your edmbuilder.cs, essentially anything inside your project folder. You would exclude the packages folder.
Now when you get the source from source control everything would be present except for the package files. Package Restore would download those and now your working copy is complete.
See NuGet's Restore Package insists on specific package versions
Is this stupid or what?
Thanks to #Kiliman for explaining that my horrible experience is "by design".
So how do you actually get the content you thought was being restored? Do you install each package one at a time. That's insane.
I was going to observe that there is no nuget equivalent of an npm install that would fetch all the packages you need ... when I discovered that there actually IS an almost-equivalent. It's just not obvious and I wonder how many people know it exists.
It's a two step process:
FIRST restore the missing packages ... THEN
Issue the command: Update-Package -Reinstall
This re-installs all packages in every project in your solution.
If you only want to re-install for a specific project, try:
Update-Package -ProjectName 'YourProjectName' -Reinstall
In both procedures, the -Reinstall switch strives to install the exact versions of the packages spelled out in your package.config ... and not newer "updated" packages which may or may not work for your project (but see the documentation for exceptions).
Read about update-package -reinstall in the official nuget documentation entitled, "Reinstalling Packages and its Pitfalls".
Do not miss the cautionary remarks. Clearly this technique is but an approximation of what you'd expect from other package managers.
Good luck, peoples.
I have an install.ps1 script in my NuGet package. This script runs both during a new install (after all the files have been copied) and during an upgrade.
I want to show a Getting Started page during a new install, but for an upgrade I want to show the Release Notes.
I found this great answer that tells how to open a URL and it works great. But I am stumped on trying to tell the difference between a new install and an upgrade.
The best solution I have come up with so far is to add a Release Notes link to the top of the Getting Started page, but that is something that could easily be missed by upgraders, and is an unwanted distraction for new installers.
I don't think it's possible to know if the current operation is install or upgrade. When NuGet upgrades a package, what NuGet does is basically uninstall the existing package and install the new package.
I suppose you could do something with install.ps1 that "dirties" the project in some way on the first install, which you will not clean up with uninstall.ps1. Maybe insert a dummy file into the project (outside of the normal NuGet handling, so the file won't get uninstalled automatically) or add some other dummy element to the project file. Then, when you see those "leftovers" from a previous install (which were purposely not cleanly uninstalled), you will know that you are installing an upgrade.
