How to restore the Intro of a package by nuget

It has always been simple to use the nuget package. Recently, if you want to toss about something, you need to parse the nuget package yourself. The user specifies the name and version of the nuget package, and then parses the corresponding nuget package and adds a reference to the project. So I want to figure out how the nuget package is restored and how to find the nuget package that has been downloaded locally.

Reference to the Nuget package

For dotnetcore projects (not counting previous project.json projects, only projects like * .csproj are discussed), they all use the new project format, the PackageReference pattern.

Example:

For dotnet framework projects, if the PackageReference package format is the same as above, and if it is in the traditional packages.config package format, there will be a packages.config file containing the referenced nuget package. Example of the file content:

This paper mainly explains the form of dotnetcore, which is PackageReference.

Restore of nuget package

After the nuget package is downloaded for the first time from nuget.org or your own package source, it will be stored in a local folder, and the next time you need the same version of the package restore, it will be obtained directly from the local package. This saved folder is part of the nuget configuration. You can find some changes to the location where nuget saves the packages folder by default on the Internet, but these articles are very similar. It only gives a solution, but it does not say why, and the basis for doing so is not explained. In fact, this solution adds a default nuget configuration file and modifies the location where the nuget package is saved.

Nuget configuration default configuration

Nuget will have some default configurations. You can refer to the official document: https://docs.microsoft.com/en-us/nuget/reference/nuget-config-file#config-section

There is a globalPackagesFolder configuration in the nuget configuration, which is used to specify the default location where the nuget package is saved. The default location on Windows is% userprofile%\ .nuget\ packages, and the default location on Linux/Mac is ~ / .nuget / packages. You can use the nuget.config or NuGet.Config configuration file to modify the default save file. In addition, you can also configure NUGET_PACKAGES to modify the location of the default nuget package by way of environment variables.

Default profile

Default configuration file for nuget, official document: https://docs.microsoft.com/en-us/nuget/reference/cli-reference/cli-ref-config#options

The location of the default configuration file on Windows is% AppData%\ NuGet\ NuGet.Config, which is also the most common solution used to modify the default location of nuget packages on the Linux/Mac. Most of them are ~ / .config / NuGet/NuGet.Config, and some may be ~ / .config (related to the system version).

This configuration file is not available by default on Windows. After adding this default configuration file, it will work globally.

Create the default configuration file% AppData%\ NuGet\ NuGet.Config, and then configure globalPackagesFolder in this configuration file to modify the default nuget package save path
