Does packages.config have to be in the project folder? - visual-studio

Trying to tidy up my file structure, I moved packages.config to a subfolder. Only to discover it was not being picked up by Nuget any more.
Is it possible to move the file or is it hard-coded into VS that it must be in the same directory as the project file?
Googling doesn't give me an obvious answer, I just get general information on packages.config's purpose.

Does packages.config have to be in the project folder?
You cannot move that packages.config file into any other sub folder except the project's root folder.
Also, I agree with thatguy.
Packages.config nuget management format allows packages.config file be in the root directory of the project and nuget and msbuild will be able to recognize this file and manage the nuget packages in your project. That's its mechanism.
So my suggestion is that you should move it back to the project's root directory. And so far, this is the only way to ensure that you successfully manage packages using packages.config.
Besides, if you still want your request to come true, I suggest you could suggest a feature request on our User Voice Forum(click suggest a feature). And The Team will consider your request carefully and I hope they will give you a satisfactory reply.

If used, packages.config is typically located in a project root. It's automatically created when the first NuGet operation is run, but can also be created manually before running any commands such as nuget restore.
This is from the packages.config reference. Although it states that the configuration file is typically located in the project root, there is no indication on any requirements for moving it. Therefore, it might be a limitation of the Visual Studio Nuget package manager that expects the packages.config file in the project root. I have never seen any official documentation or a working example of moving this file without breaking the package manager.

How do I load code into a specified directory using Nuget?

I have the situation where our code base is like so:
/Gui/
/Product1/
/Calc engine/
/Core/
/Product2/
All of these projects are loaded into a Global solution file in Visual Studio.
I want to extract Core to it's own repo and allow different branches of this repo to load different versions of it. I cannot just use references to the binaries as engineers want to be able to debug the core code when running the Products so I have to be able to bring the entire Core codebase in.
Originally, I intended to use git submodules but I am investigating whether Nuget might be a better solution. I have removed /Core/ to it's own repo and created a Nuget package of the Core directory (it contains about 20 different C# projects).
Is there a way I can input this Nuget package into the Global Solution? It would need to put the code into the same directory as it used to rather than a package director.
Is there a way I can input this Nuget package into the Global Solution? It would need to put the code into the same directory as it used to rather than a package director.
You can change the Package Management to "Pakcage.config" in Options\Nuget Package Manager. The package will be stored in solution directory.
and right-click the solution in solution explorer then click "Manage Nuget Packages for Solution"

This project references NuGet packages that are missing on this computer (TFS)

I'm using TFS for the first time and attempting a build. I'm getting the error:
This project references NuGet package(s) that are missing on this computer. use NuGet Package Restore to download them.
I realize that there are many similar posts on StackOverflow and I've searched through quite a few of them. What I've gathered is that the two boxes under Package Restore in Package Manager Settings should be checked (but that this is also irrelevant now because they're checked by default). I verified that mine were both checked anyway.
The next piece of advice I considered is deleting the /packages folder from the Source Control version of my application. There is no packages folder there OR in my local (pre migration to TFS) version of the application. Instead, there's a ../packages/ folder (up one level) from the application folder. It seems that, at some point, I've opted to store the packages for all of my applications in the same folder? If so, where is this setting and what do I need to change it to either in my local version or in Source Control Explorer?
Thanks!

Nuget Reinstalling Packages - updating incorrect packages folder

In my projects folder root, I have a packages folder that is utilized by various web applications at C:/Projects/packages. All application references that point to this folder work fine.
However, with a new application, when I pulled the latest code, all references expect the packages folder to live at the solution level - C:/Projects/CompanyName/Apps/SolutionFolder/packages.
When I pull latest, this folder is not included (it's never checked in to subversion) so I have missing references when I first open a project up. However, when I try to build, it doesn't pull the latest for these packages and of course, doesn't compile. When I run Update-Package -reinstall, it will update the packages IN C:/Projects/packages, and it WILL NOT create the packages folder at the solution level.
I've confirmed that I have the packages.config in each project in the solution and that each project expects that the assemblies will be housed in the packages folder at that level. What's weird is that after I run the -reinstall, these hintpaths in the project files will actually point to the C:/Projects/packages folder and the assembly references will resolve...but only for 3rd party packages and NOT for our in-house built packages.
Does anyone know why this occurs? The solution has been to get a copy of the packages folder that a coworker is using and paste that into the solution folder but that doesn't solve the problem if it occurs again.
Per #MattWards link I checked the nuget.config file in appdata, which specified this C:/project.packages path. After removing this setting and building my solution, the packages folder was added to the solution level and everything worked.

How do I reference instead of copy js files from a Nuget package at build time in TeamCity?

I've got a packages.config file checked into source control. This specifies the exact version of the Nuget dependency I want. We have our own NuGet repository. We are creating these NuGet packages ourselves.
<packages>
<package id="Dome" version="1.0.0.19" targetFramework="net45" />
<package id="Dome.Dojo" version="1.0.0.19" targetFramework="net45" />
</packages>
These packages have some JavaScript files which when you add the Nuget package as a reference in Visual Studio are copied to the Scripts folder in the project.
I don't want to check these JS files in to source control, I just want to check in the packages.config file.
When my project builds in Team City (or when I build in Visual Studio after a fresh checkout) it doesn't copy the JS files from the NuGet package. There's a question here explaining a similar problem:
NuGet package files not being copied to project content during build
But, the solution in the answer to that question doesn't work for me; that solution uses ReInstall, which is problematic because it can automatically upgrade the version in the packages.config file (say if a dependency is specified as a >=).
The whole point of this is that I want to be able to checkout a revision from my source control, and build that version with the right dependencies AND I want to use the nice packaging features of NuGet. So, I don't want any "automatically update to the latest version during the build."
There's an issue against NuGet (http://nuget.codeplex.com/workitem/2094) about NuGet files not restoring content files. And it's Marked as Closed By Design.
Thinking about how this works a little more, it appears to me (but I'm not 100% sure) that for assemblies NuGet has a different behaviour - it doesn't copy them into the project, instead it references them from the location in the packages folder. It strikes me that js files in the NuGet package should be referenced analogous to how dlls are referenced.
Is there a way to construct a NuGet package so that it references the JS as links in the project (in a similar way to how you can add an existing File as a Link in VS)? And would this solve my problem?
If not then I'll take the advice given by Jeff Handley when closing ticked Nuget Issue 2094 mentioned above:
The option you'd have is to create a new console executable that
references NuGet.Core, and you could build a supplemental package
restore for your own use that copies package contents into the
project.
Writing my own command line tool to copy the contents does seem like I'm pushing water uphill here - am I doing something fundamentally wrong?
The underlying problem here is Visual Studio's relatively poor support of JavaScript projects and JavaScript's lack of built-in module loader.
For C#, when you install a package it adds a reference in your .csproj file to the assembly on disk. When you build, MSBuild knows to copy the thing referenced to the bin directory. Since you aren't checking in your bin directory, this all works great.
Unfortunately for JavaScript, the build system isn't nearly as matured and there aren't well defined guidelines for NuGet to follow. Ideally (IMO), Visual Studio would not run web sites directly from your source directory. Instead, when you built it would copy the JavaScript files, CSS and HTML files to a bin directory from which they would be executed. When debugging, it would map those back to the original JavaScript or TypeScript files (so if you make a change it isn't to a transient file). If that were to happen then there is now a well-defined build step and presumably a well-defined tag for JavaScript files (rather than just "content"). This means that NuGet would be able to leverage that well-defined MSBuild tag and package authors could leverage the NuGet feature to do the right thing.
Unfortunately, none of the above is true. JavaScript files are run in-place, If you did copy them to bin on build Visual Studio would do the wrong thing and editing from a debugger would edit the transient files (not the originals). NuGet therefore has no well-defined place to put files so it leaves the decision up to the package author. Package authors know that the average user is just going to be running directly from source (no build-step) so they dump files into the source folder where they must be checked in to version control.
The entire system is very archaic if you are coming from a modern ecosystem like C# where someone took time to think these things through a bit.
What you could do is create an MSBuild task that, before build, would go through all of your packages, look for content, and copy that content to the desired location. This wouldn't be terribly difficult, though would take a bit of work.
Also, package authors could include a build-task that does this in their package so that before-build all of their content was copied local. Unfortunately, if only some package authors do this then you end up with weird fragmentation where some packages need to be committed to version control and others do not.
When a package is installed into a project, NuGet in fact performs these operations,
Download the package file from source;
Install the package into the so called packages folder, which is $(SolutionDir)\packages by default;
Install the package into the project, which consists of adding references to DLLs, copying content files into the project directory etc.
When a package is restored, only the first two steps are executed. Projects will not be touched by nuget package restore. Which is why the js files in your project will not be "restored".
The only solution for now is to check in the js files in your project.
If you are the owner of the package then you could use the nuget package i've created to be able to have a folder called "Linked" in the package and have a simple Install.ps1 and Uninstall.ps1 (one liners) to add every file in the nuget package's linked folder as existing to the project.
https://github.com/baseclass/Contrib.Nuget#baseclasscontribnugetlinked
I didn't try out how publication treats linked files, the problem is debugging the Project, as the JavaScript files will be missing in the directories.
If you are using git as source control you could try my nuget package which ignores all the nuget content files and automatically restores them before building.

Should .nuget folder be added to version control?

With newer versions of NuGet it is possible to configure a project to automatically restore NuGet packages so that the packages folder doesn't need to be included in the source code repository. Good.
However, this command adds a new .nuget folder and there is a binary there, NuGet.exe. This can also be re-created automatically by Visual Studio and so it doesn't feel correct to add that to version control. However, without this folder Visual Studio won't even load the solution properly.
How do you people deal with this? Add .nuget to source control? Run some command line script before opening the solution?
This post is old, you should not be using solution level NuGet package restore anymore. As of version 2.7+ there is an option in the NuGet setup to automatically restore packages on build.
So the .nuget folder can be deleted and the option removed from your projects.
http://docs.nuget.org/docs/reference/package-restore
UPDATE: With the release of NuGet 4.x and .NET Standard 2.0, when you use the new csproj format you can now use package references, ironically reintroducing the dependency on msbuild to restore packages, but now packages are a first class citizen of msbuild. The link above also makes mention of the PackageReference, but the following announcement details it better:
https://blog.nuget.org/20170316/NuGet-now-fully-integrated-into-MSBuild.html
And the NuGet 4.x RTM announcement, which ironically isn't as useful:
https://blog.nuget.org/20170308/Announcing-NuGet-4.0-RTM.html
UPDATE 2: Apparently with VS2017 you can even use package references with classic csproj projects, but they aren't backwards compatible anymore, and there have been some problems with restoring package sub-dependencies. I'm sure that will all be resolved.
#Richard Szalay's answer is right - you don't need to commit nuget.exe. If for some reasons Visual Studio does not automatically download the nuget.exe, make sure you have the following set to true in the nuget.targets file:
<!-- Download NuGet.exe if it does not already exist -->
<DownloadNuGetExe Condition=" '$(DownloadNuGetExe)' == '' ">true</DownloadNuGetExe>
Close the VS solution, reopen it and build it. Visual Studio should download nuget.exe automatically now.
According to this thread, the .nuget folder should be version controlled.
You need to commit .nuget\nuget.targets, but not nuget.exe. The targets will download the exe if it doesn't exist, as long as you change DownloadNuGetExe to true in nuget.targets
Although I usually don't like the idea of adding exe's to source control, I would suggest that source control should contain anything that is required in order to open, build and execute the project.
In this case it sounds like the .nuget folder is a required dependency. Therefore it ought to be under source control.
The only question left, that you need to research, is how NuGet is going to react if that folder is marked read-only, which TFS will do once it has been checked in.
Update:
I did a little more research on this as I've never used NuGet before. http://blog.davidebbo.com/2011/03/using-nuget-without-committing-packages.html
I would suggest that probably what you want to do is make NuGet a requirement that has to be installed on every developers workstation.
Further, you should place in source control the batch file required to get a workstation ready to start editing the project. The batch file is going to run the commands necessary to get and install the dependency packages.
Beyond that I'd say you might want to contact NuGet directly to ask them how, exactly, this is supposed to work.
Now that nuget supports package restoration we're looking at it more closely.
We use Subversion for source control, and my initial thoughts are that .nuget should be added to our repository, but added using svn:externals so that it points to a single location.
That way we can automatically push out new versions to all developers and projects. For projects on release branches, rather than HEAD, we can specify the revision of svn:externals reference if we want to leave nuget alone.
We have a lot of projects, so it also means not duplicating nuget.exe multiple times in the repo.
We have the nuget.config file in the folder, as it has the references to our internal Nuget server, using the Package Sources area:
https://docs.nuget.org/consume/nuget-config-settings
Apart from this reason, you should let Visual Studio handle the downloading of packages.
