I cloned .NET 5 project, which should be working (unfortunately, I can't provide the project so you could reproduce the problem). I didn't change anything, I just wanted to build it, however, I am getting this error when restoring packages (although the project itself is on different disk, I found out that this is "global-packages" folder):
Could not find a part of the path 'C:\Users\me\.nuget\packages\microsoft.aspnetcore.azureappservices.siteextension\5.0.5\content\store\x64\net5.0\microsoft.extensions.configuration.environmentvariables\5.0.0\lib\netstandard2.0\Microsoft.Extensions.Configuration.EnvironmentVariables.dll'
However, I don't think it is a problem with this particular dll, as my colleague cloned the same project and he is getting the same error, but with different library.
This is what I've already tried doing:
Clearing all nuget cache
Checking "automatically check for missing packages during build in visual studio"
Updating everything I could (VS, nuget..)
Running VS as Administrator
Checking package sources (yes, nuget.org is there)
Adding "add key="repositoryPath" value="$..\..\packages"" into the nuget.config file - this didn't actually create the package folder in the defined path
Clean/rebuild/... everything
I think, that the problem will be in some setting, but I have no idea, where to look :/
Use the command dotnet restore
instead of
dotnet nuget

My CruiseControl.NET build server is not able to restore the nuget packages of my projects. According to some websites it should be enough to set the environment variable EnableNuGetPackageRestore to "true" and restarted Cruise Control after that, but that didn't help in my case.
What else can I do?
Do i need to install something that "enables" Nuget?
I noticed I have a .nuget folder in C:\Users\MyUser\ but I don't have this folder on the build server. Is this required? Who created that on my pc? Visual Studio?
Without seeing the project config, I am assuming you are using either a Microsoft Solution or project, and are building from that using the msbuild task in CC.net. If so, your Solution needs a .nuget folder structure (in the same location as the sln/prj file there needs to be a .nuget folder, inside that folder, you need a NuGet.Config and a NuGet.exe as well as a NuGet.targets).
This should be automatically added to your solution if you right click on it inside visual studio and select "Enable nuget Package Restore".
You can find more information # Nuget Documentation. There is quite a few ways to skin this cat, but, based on your initial statement, you are just missing the .nuget folder in your Solution, and once added it should just work. Otherwise, you have to look at pre-build tasks, and that gets a little more detailed than is usually necessary.
What can I do to fix this build? Entity Framework was added to this project via NuGet.
All projects compile without issues on local system. But the build fails on Visual Studio Online.
By turning on Diagnostic logging, I am able to trace to this warning which makes my builds failed:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets(1605,5): warning MSB3245: Could not resolve this reference. Could not locate the assembly "EntityFramework.SqlServer". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.
DO NOT right-click the project and chose "Enable NuGet Package Restore". This is the "old way" of doing package restores as per the Nuget Docs.
Package restoration should happen as part of the build process by default. If it's not (which seems to be the case), you've got a different problem, but there's not enough information to say what.
I am able to resolve this error simply by right clicking at the solution in Solution Explorer and select Enable NuGet Package Restore.
That adds a few more files to my solution and modify a few project files. The build server can then restore the packages at build time and is happy in the end.
So, the error I'm getting when my build server builds my project is:
Package restore is disabled by default. To give consent, open the
Visual Studio Options dialog.
I'm aware of what this error means and how to resolve it. The problem is I cannot change anything on the build server - my company won't allow it. Additionally, creating an environment variable called EnableNuGetPackageRestore and setting it to true is not an option because that involves modifying the build server.
My question is: is it possible to simply check all of the NuGet packages that are part of a solution into source control so then the build server won't have any reason to go out and re-download them? If so, then perhaps you could explain why this error is still happening, when I've verified that all of the NuGet packages (.nupkg) are in the packages folder in source control:
Second Question: Forgive my ignorance, but what is the reason for the "package restore" feature? Is it to ensure that each package is up to date with the latest version of that package? It seems to me that this "feature" should be a setting that shouldn't hinder building a project on a build server. In my mind, if we want the build server to look for newer packages, then sure, do it, otherwise if I have all my packages in source control and we tell the build server somehow to NOT look for newer packages, that sounds reasonable to me.
So, my situation specifically was I downloaded the source code for the actual Nuget site (to create an internal implementation of Nuget in my company), and when I tried to deploy it, that's when I got the error above.
What I had to do was:
Delete the .nuget folder.
Within your file system (not via Visual Studio), modify the .csproj files (delete where it said <packageRestore>true</packageRestore>, as well as where it imported the project that had nuget.targets in the line - just do a "find" for "nuget.targets", and delete all lines that have an import.
Save your .csproj file changes.
Check in your changes into TFS.
Deploy your solution.
I am building an MVC4 web application with VS2012 professional with NuGet Package Manager version 2.2.31210. I have multiple projects in my solution, all sharing various packages I installed using NuGet. One of my projects is an MVC4 web application where I am using packages such as bootstrap, jquery UI, etc, all installed using NuGet.
When I clone a fresh copy of my entire solution from my repository and build my MVC4 project, the package restore feature seems to be working: it creates the packages directory under the solution direcotry and populates it will all the versions of the packages I expect to see. However, the content files do not get copied to the appropriate places in the MVC app directory. The weird thing is that it does create directories for the content, but does not copy the content files themselves.
For example, I am using the Twitter Bootstrap package which appears in the packages/Twitter.Bootstrap.2.2.2. In the MVC project a directory called bootstrap (containing css, img, and js directories) gets created in the Content directory. But, no css or js files are copied into those directories!
Does anyone have a clue what magic incantation I must utter to get the build to copy these content files from the NuGet packages directory?
This is a very common issue we are all having. I've created an MSBuild Task NugetContentRestoreTask that will do this trick for you. Run the following command in the Package Manager Console:
Install Nuget Content Restore MSBuild Targets
PM> Install-Package MSBuild.NugetContentRestore
The only thing left is to call it from your BeforeBuild Target with something like this:
Project File Targets
<Target Name="BeforeBuild">
<NugetContentRestoreTask SolutionDir="$(SolutionDir)" ProjectDir="$(ProjectDir)" />
</Target>
You can take a look at the source repo and find it on nuget.org
Additional Content Folders
This nuget only includes the default folders scripts, images, fonts, and content, it is not a recursive directory includes. For additional content subfolders - you must assign the property AdditionalFolders.
<Target Name="BeforeBuild">
<NugetContentRestoreTask SolutionDir="$(SolutionDir)" ProjectDir="$(ProjectDir)"
AdditionalFolders="less;sass;common" />
</Target>
I have found a workaround, but it is ugly. By executing the following command in the NuGet Package Manager Console: Update-Package -Reinstall all the files are indeed copied to their proper places within the Mvc project Content and Scripts directories.
Unfortunately, this is risky because you are likely to end up with the wrong versions of certain packages. For example, in my case after the command finishes executing (which takes quite a while by the way), I end up with jQuery version 1.4.4. This is way old, and I assume it must be an explicit dependency of some other package that is being updated. So it appears that the order in which the packages actually get updated by NuGet is significant (it does not appear to parse the entire dependency tree for all packages and pick only the latest versions from the union of all dependencies, which seems like it would be the preferred behavior). Rather, as the command executes I see it replacing the jQuery package several times with different versions as it works its way through all the packages and their dependencies, only to end up with a very old version.
A similar approach is the execute the Update-Package -Reinstall command explicitly for each package that is causing my problem, but this is incredibly tedious and error prone.
The NuGet Package Restore feature should yield the same result as manually executing the Install-Package or Update-Package -Reinstall command for a package, but it does not.
I don't like to have the thirdparty JavaScript files under source control either. Thats why I've followed Jeff Handley advice in http://nuget.codeplex.com/workitem/2094 to create a solution my self. I didn't go the executable way, but created a nuget solution level package which does the trick.

It's tied to git, as it automatically updates the .gitignore file.
Short description:
Ignore nuget content files in git:

I've written a blog post describing how to use it.

In Visual Studio 2015 Update 1, they now support contentFiles. The caveat with this is that it only works in projects that use project.json.
In reference to the problem that you are having, there is a good blog post that explains why you see this behaviour: NuGet Package Restore Common Misconceptions.
For my projects it turned out that content files work with PackageReferences only:
Existing project with nuget references via packages.config
Installed NuGet package with content files
Build project
No content files in output directory
Conversion of packages.config to PackageReferences
Build project
Content files have been copied to output directory
IDE is Visual Studio 2017. The project is an application project which means it is in the old csproj format.
I ran into an issue recently with NuGet restore. I added a project dependency (in this case PostSharp) and then enabled restore. I checked in the source, but not the /packages directory (as I shouldn't needed to....right!). When TeamCity or another developer grabs the source and runs MsBuild, they receive the following error:
C:\TeamCity\buildAgent\work\e374975c0264c72e\ProjectName\ProjectName.csproj(70, 3): error MSB4019: The imported project "C:\TeamCity\buildAgent\work\e374975c0264c72e\packages\PostSharp.2.1.5.1\tools\PostSharp.targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.
The problem is, NuGet hasn't run yet to restore/download PostSharp or it's .targets file. This feels like a NuGet bug to me, but wanted to see if others have this same issue.
Anybody have this issue or know the resolution. Yes, I could check-in the /packages directory, but then why use NuGet at all?
Another approach is to modify the <Import> element in question, to make it conditional, e.g.:
<Import Project="$(CodeAssassinTargets)" Condition="Exists($(CodeAssassinTargets))" />
This depends on a new property defined in an earlier <PropertyGroup>. I usually add one at the top of csproj file with other "global" flags, e.g.:
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
<CodeAssassinTargets>$(SolutionDir)packages\CodeAssassin.ConfigTransform.1.1\tools\CodeAssassin.ConfigTransform.targets</CodeAssassinTargets>
<AutoParameterizationWebConfigConnectionStrings>false</AutoParameterizationWebConfigConnectionStrings>
<UseMsdeployExe>true</UseMsdeployExe>
</PropertyGroup>
Then in an appropriate target, like BeforeBuild, give a helpful error message:
<Target Name="BeforeBuild">
<Error Text="CodeAssassin.ConfigTransforms target is missing. It needs to exist at $(CodeAssassinTargets) in order to build this project!" Condition="!Exists($(CodeAssassinTargets))" />
</Target>
With these modifications, the project will load even if the nuget package restore has never been done. If auto package restore is enabled, the first build attempt should clear up the missing target issue, but if it does not, one manual package restore will.
#porterhouse91, have you checked your csproj file to make sure it has been set up with the appropriate build target?
I haven't yet tried the new built-in Package Restore feature, but I'm assuming it works at least somewhat like the previous workflows out there on the interwebs. If that's the case, enabling Package Restore in your solution only affects the projects in your solution at the time you enable it. If you've added a new project (having NuGet dependencies) to the solution since enabling Package Restore, you're gonna need to enable it again.
Another possibility: the previous workflows involved having a .nuget folder that you needed to check in to VCS, so you might need to check that in if it hasn't been checked in yet (if the built-in Package Restore feature does indeed use this approach).
BTW, if this answer is at all helpful, thank Stephen Ritchie -- he asked me to give it a shot for you.
I had a problem like this as well, but I was able to modify the .targets file in the source package to work around it. Basically, RestorePackages is a build target that runs when the project is built. Unfortunately, the package won't even load properly before the imports are satisfied. The only way I know to fix this is to include the .targets file as content and then change the BuildDependsOn property so it restores the packages before it runs your custom tasks.
<PropertyGroup>
<BuildDependsOn Condition="$(BuildDependsOn.Contains('RestorePackages'))">
RestorePackages;
CustomTarget;
$(BuildDependsOn);
</BuildDependsOn>
<BuildDependsOn Condition="!$(BuildDependsOn.Contains('RestorePackages'))">
CustomTarget;
$(BuildDependsOn);
</BuildDependsOn>
</PropertyGroup>
To be clear, this doesn't help with pre-built packages, but if you can build the package again yourself, you can fix it.
I ran into this same issue with Visual Studio 2012 and NuGet packages not checked into source control.
The error:
The imported project "\packages\Microsoft.Bcl.Build.1.0.7\tools\Microsoft.Bcl.Build.targets" was not found.
Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.
I found a msdn writeup on the situation that gave the following workarounds for grabbing a project from source control without the NuGet packages.
Stop using package restore and check-in all package files
Explicitly run package restore before building the project
Check-in the .targets files
I decided to go with option #2, however, NuGet currently (v2.6) does not include a way to install all packges from the packages.config file from within visual studio. Some searching revealed that you need to use the NuGet Command Line to execute the following command before opening Visual Studio (reference).
c:\path\to\nuget.exe install -o packages project-folder\packages.config
