I was recently in an air plane, writing code, when I realised that I needed to add a couple of NuGet packages to my code base. I was on one of those less-travelled flights in Europe, on board an Embraer E190, and as is usually the case on those 1-hour flights, there was no WiFi.
Adding a NuGet package typically requires that you're online so that the tools can query the relevant NuGet repository. You'll need to download the package, so if you're offline, you're just out of luck, right?

Fortunately, I'd previously used the packages I needed in other projects, on the same laptop. While I'm no fan of package restore, I know that the local NuGet tools cache packages somewhere on the local machine.
$ dotnet add package unquote Determining projects to restore... Writing C:\Users\mark\AppData\Local\Temp\tmpF3C.tmpinfo : X.509 certificate chain validation will use the default trust store selected by .NET.info : Adding PackageReference for package 'unquote' into project '[redacted]'.error: Unable to load the service index for source : No such host is known. (api.nuget.org:443)error: No such host is known.
Clearly the dotnet tool was trying to access api.nuget.org, which, obviously, couldn't be reached because my laptop was in flight mode. It occurred to me, though, that the reason that the tool was querying api.nuget.org was that it wanted to see which version of the package was the most recent. After all, I hadn't specified a version.
After looking around a bit, I found a subdirectory named AppData\Local\NuGet\v3-cache. This directory contained a handful of subdirectories obviously named with GUIDs. Each of these contained a multitude of .dat files. The names of those files, however, looked promising:
As you can tell, list_unquote_index.dat is much larger than list_unquote.dat. Since I didn't know what the format of these files were, I decided to look at the smallest one first. It had this content:
$ dotnet add package unquote --version 6.1.0 Determining projects to restore... Writing C:\Users\mark\AppData\Local\Temp\tmp815D.tmpinfo : X.509 certificate chain validation will use the default trust store selected by .NET.info : Adding PackageReference for package 'unquote' into project '[redacted]'.info : Restoring packages for [redacted]...info : Package 'unquote' is compatible with all the specified frameworks in project '[redacted]'.info : PackageReference for package 'unquote' version '6.1.0' added to file '[redacted]'.info : Generating MSBuild file [redacted].info : Writing assets file to disk. Path: [redacted]log : Restored [redacted] (in 397 ms).
This way I managed to install all the NuGet packages I needed. This was fortunate, because I had so little time to transfer to my connecting flight that I never got to open the laptop before I was airborne again - in another E190 without WiFi, and another session of offline programming.
I spend several hours each week on long-distance train journeys and often use the time to code, whether on a pet project or practising a kata or two. Large parts of this journey have patchy-at-best mobile data coverage, so tools with a reliance on a stable internet connection can cause problems. One of these tools is the NuGet Package Manager in Visual Studio.
Now that you have added the local package source, you will be able to use your offline local repository from within Visual Studio in the usual way, either via the Console or via the Package Dialog, by selecting it from the Package Source menu, without the need for an active internet connection:
It is worth noting here that if you downloaded any pre-release packages from nuget.org into your local repository they will not be displayed by default within either the Package Manager Console or GUI dialog. This is by design, however it can be overridden in the Package Manager Console through the use of the -IncludePrerelease flag. For more information, see the official documentation.

A NuGet package contains reusable code that other developers have made available to you for use in your projects. You can install a NuGet package in a Microsoft Visual Studio project by using the NuGet Package Manager, the Package Manager Console, or the .NET CLI. This article demonstrates how to create a Windows Presentation Foundation (WPF) project with the popular Newtonsoft.Json package. The same process applies to any other .NET or .NET Core project.
After you install a NuGet package, you can then make a reference to it in your code with the using statement, where is the name of package you're using. After you've made a reference, you can then call the package through its API.
To find a NuGet package, start with nuget.org. Browsing nuget.org is how .NET developers typically find components they can reuse in their own applications. You can do a search of nuget.org directly or find and install packages within Visual Studio as shown in this article. For more information, see Find and evaluate NuGet packages.
You can install a NuGet package into any .NET project if that package supports the same target framework as the project. However, for this quickstart you'll create a Windows Presentation Foundation (WPF) Application project.
To install a NuGet package in this quickstart, you can use either the NuGet Package Manager or the Package Manager Console. Depending on your project format, the installation of a NuGet package records the dependency in either your project file or a packages.config file. For more information, see Package consumption workflow.
After the Package Manager Console pane opens, verify that the Default project drop-down list shows the project in which you want to install the package. If you have a single project in the solution, it's preselected.
About Activities Feeds Studio uses NuGet feeds to install activity packages. These feeds can be handled in two ways in Studio: application level - feeds are configured from the Settings > Manage Sources tabproject level - feeds are configured from...
I'm setting up a new PC to do development on. Got VS 2019 Community Edition. I went to install Entity Framework Core, but couldn't. It cannot be found. All that I could find was "Microsoft Visual Studio Offline Packages". I searched on that term and came across this article on the archived MSDN forum on this topic. I tried adding NuGet, following the example on the link I have, using for the URL. It doesn't work. All I'm getting is errors like this:

I was hoping to get to that NuGet package, but never did. The issue is that when I open the Manage Packages for Solutions, then go to the Browse tab, nothing is there. No NuGet packages of any sort at all. It's just blank.
The DevExpress Unified Component Installer creates a local NuGet feed with DevExpress .NET Framework and .NET assemblies, and registers this feed in your Visual Studio 2019/2022 IDE as a package source. This is the easiest method to install DevExpress products (it does not require manual configuration).
Download the Unified Component Installer and install the registered or trial version of DevExpress products. The installation copies all NuGet packages to the C:\Program Files\DevExpress 23.2\Components\System\Components\Packages directory and configures a local NuGet feed for each installed Visual Studio version.
This step is optional and is required if you are adding, removing, or updating DevExpress NuGet packages manually. If you use DevExpress Project Wizards to create solutions, this step is not required (new projects will already contain necessary references to DevExpress NuGet packages).
The ability to find and install PowerShell modules from online sources like Nuget makes life for a Windows admin a smidge nicer. On the flipside, arbitrary trust of online package repositories and granting servers outbound internet access can be a nightmare for those tasked with protecting a network.
I was recently going through the process of installing the developer tooling I use on a fresh, new laptop. I installed the usual suspects like Visual Studio and Visual Studio Code as well as a few other tools I use often most of which can be found here. Once I was finished with installation, I launched Visual Studio and created a new ASP.NET Core Web API project. When attempting to build the solution I received the following NU1101 error for all of the package references telling me that the package restore had failed.
After modifying the file, I restarted Visual Studio and built the solution. It worked! I am now able to use the NuGet package manager to install packages and build project moving forward. Hope this helps others affected by this or similar issues!
PowerShell modules allow you to easily extend the capabilities of PowerShell by bundling together various cmdlets, functions, variables, etc., into a single package. Modules are incredibly useful for automating administrative tasks, scripting workflows, and boosting your productivity as a system administrator.
While most PowerShell modules are distributed via the online PowerShell Gallery repository, sometimes you may need to set up a module while working in an isolated offline environment with no internet connectivity. Offline PowerShell module installation comes up often when dealing with secured environments like government agencies or financial institutions.
In this comprehensive guide, we will explore step-by-step methods to install a PowerShell module in offline mode from a .nupkg file or extracted folder structure. Whether you are a beginner or an experienced PowerShell scripter, this guide aims to provide detailed instructions to suit all levels. 152ee80cbc
