Cross platform Xamarin Forms project in Visual Studio and Visual Studio for Mac. The project references Akavache. Akavache has a dependency of akavache.sqlite3. I have made a custom change to a DLL in the akavache.sqlite3 repo and built the DLL locally, and would prefer not to have to switch the whole Akavache package tree over to a custom build for all the Akavache dlls and dependencies. So essentially...would like to continue referencing the NuGet package like normal but "substitute" one DLL on the fly. Or something equivalent like that!
But it needs to be portable too. At first I used a post build copy command to overwrite the "standard" dll that gets put in the TargetDir. That works in the sense that it copies to TargetDir, but for Android copying the DLL into the TargetDir does no good. The DLL is already incorporated into the APK in the TargetDir instead. So it would need to happen some other way. Same basic issue if you used MSBuild instead of a post build command line.
Any thoughts?
FWIW, my current workaround is to copy the DLL over top of the cached NuGet package location. But the problem with this approach is anytime the cache would get cleared/updated it needs to be reapplied. That's also not an obvious step to do, or easily automated, when another developer want to get set up on their machine.
Any .nupkg files are just ZIP files with some metadata, so you can change at the contents. The NuGet Package Explorer should make it a little easier to view the contents.
The NuGet Gallery (e.g. https://www.nuget.org/) has a "Download" link on the left hand side, otherwise just install the package into an empty project and then take a peek.

I've added Autofac library using NuGet and I see it in my references as shown below.
But when I check the properties [F4] of Autofac by clicking on it, it shows empty property box in Visual Studio.
Also, I don't see Autofac folder under packages folder.
I see only Package reference in .csproj file. Then how does it locates the DLL? Where is the actual DLL? I see it's automatically coming inside BIN. How does it come?
Main Issue: Locally I'm able to build the solution but same solution fails on TFS build agents. It's unable to find the NuGet reference. So where can I find DLL references? or how to push it to TFS?
As #magicandre1981 already explained, with PackageReference style package referencing (as apposed to package.config-style, also see this for more background on the differences, in case you didn't know), the packages are not located in a per-solution packages-folder, but in a central one (by default %USERPROFILE%\.nuget\packages). Albeit you can easily change the location using the NUGET_PACKAGES environment variable (which also works as a TFS Build variable, because they are provided as environment variables to build steps).
Furthermore, inside Visual Studio you see no path, because the actual path to the DLL is determined at build time. You can see part of that path in your <project-dir>\obj\project.assets.json file (which is generated during the restore target/operation), but the full path you will only see in the MSBuild logs (for example when actually calling the csc.exe executable/C# compiler or during ResolveAssembyReferences-task).
Note that for .NET Core, i.e. "SDK style" projects, the path is actually shown in properties (as are the actual DLLs in a node underneath the "package" node.
One can only assume that the integration of PackageReference in "old" projects is not fully done yet (if ever).
For comparison a PackageReference in an "old" / non-SDK-style project:
You use the new Package Reference where the NuGet files get get stored into a cache:
Solution-local packages folders are no longer used – Packages are now
resolved against the user’s cache at %userdata%\.nuget, rather than
a solution specific packages folder. This makes PackageReference
perform faster and consume less disk space by using a shared folder of
packages on your workstation.
Assume you are using TFS 2015, the NuGet Restore task name should be NuGet Installer which under Package when you add tasks.
So, if you have installed Nuget in the build machine, then you can use the task directly.
You can also custom nuget.exe for TFS 2015 build -- Just specify the Path to NuGet.exe
You can refer to Mummy's blog- Custom nuget.exe for TFS 2015 build for details.
Add a NuGet Restore task to your build so that the packages are restored.
We have a set of functionality that was previously in a regular dll file, but that is now in a Nuget package. Naturally, we want to pull it using Nuget instead of having to download and update the dll:s manually. All projects are handled in VS 2013, so we have access to it through the package manager.
Now, we need to go over all the projects in the source tree to update the reference to be a nuget reference instead of the old dll reference.
You can do this on a solution level using the package manager, but since there are several dozens of solutions and well over a hundred projects I'd rather not do it manually.
Is there a way to automate this? That is, to iterate through the source tree, find every .sln file and update the references in its underlying project files?
You can probably do it by writing a small C# program. Install NuGet.Core and NuGet.VisualStudio package to the program to use functions in nuget.core.dll and nuget.visualstudio.dll, plus some DTE functions.
I have a project with a few front-end frameworks obtained via and managed by Nuget (Twitter Bootstrap, jQuery, jQuery UI ...).
I want to keep the files in my project, but remove them from Nuget's grip (I don't like the way Nuget organizes these files).
When I un-check the project for a library Nuget removes all the files it had installed, unless I've editted them (e.g. I over-wrote bootstrap.css with a customized version from getbootstrap.com).
As I do this from time-to-time, instead of backing up the /Content and /Scripts directories and adding back in the relevant files after removing the library from Nuget, I'd like to be able to dissociate all files of a particular library from Nuget at once without removing them from the project's directories. Is that possible, by either the GUI or the console?
I don't know if this issue is specific to a version(s) of Visual Studio, but mine is VS 2012
Can you elaborate for the part of "I don't like the way Nuget organizes these files"? If you remove NuGet from the picture, the good things that it does for you (detection of package updates, automatic package restore etc.) will be gone.
If you absolutely need to do this, one possible hack would be deleting packages.config from the project.
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.

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.

I need to copy standard component DLLs into a standard folder defined in every VS2012 project when the project is opened. We're not allowed to store DLLs in Subversion so I need to reload this folder every time a developer opens the project/solution. I'm looking for an automation solution that will pull DLLs from a centralized location and copy them into the developer's solution. I looked at Visual Studio Extensions but it seems like an awful lot of work just to copy a couple of files. Are there any other hooks in VS2012 (and hopefully VS2010) where I can code simple PowerShell scripts to copy these files?
It turns out AntHillPro has it's own functionality for storing common DLLs and loading them into folders in your Solution before building. It's not as elegant as an MSBuild pre-build task but it fits in with the model followed by our Java builds with some slight tweaking.
Why you just do no use Nuget? Adding nuget reference and enable nuget restore on build will do exactly what you need. You can create nuget repository as shared folder.
