Update DLL reference - visual-studio

I wanted to update some DLLs used in my .NET project to the latest version and I've noticed that, if I replace the DLLs on the file system with their new versions, VS 2012 updates the DLL version number in the Properties window.
Is this some new feature of VS 2012? I don't remember seeing it in VS 2010 (I expected it would need more manual handling).
Is this working right, or should I remove and re-add the DLLs manually from the references, just to be sure?
Anyway, my project compiles and runs fine, so I guess it works...
EDIT:
I guess it works because the DLLs are not strongly named (http://msdn.microsoft.com/en-us/library/wd40t7ad.aspx)?
Perhaps I should re-add them if they were...
Inside the project file I saw it had the old version number, but in the properties window I saw the new one...
Thanks!

Easier option to refresh / reload references & types DLL (for example COM interop types) without re-adding all DLLs one-by-one is to reload all projects that reference it like this:

It's better to remove and re-add your references. You said it yourself that the project file was not up-to-date.
I am not sure if there is an add-on for VS that could make updating DLLs easier. If there isn't one, definitely someone should make one. Changing assembly references in large projects is a pain in the #ss.

What worked for me is - go to 'manage nuget packages' and update all.

Managing references as NuGet packages is significantly easier. You can view which references became out of date and choose which to update.
Downside: if you are not using the standard packages (available via NuGet.org) you have to manage your own NuGet repository.
You can manage your NuGet packages via GUI or console.
NuGet packages manager GUI

better option is to de refrence the dll and refrence again but make sure for safety purpse you keep the backup of your previous dll...

How to use a custom version of one DLL otherwise found in via referenced NuGet package?

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.

Confusion over NuGet in Visual Studio

Our VS2013 solutions contain a solution folder called .nuget, containing the files NuGet.config, NuGet.exe, NuGet.targets. What is the significance of this folder and what uses the files? Is it related to the "enable package restore" feature?
If I install or update a package (via the "Manage NuGet Packages" UI or package manager console), does this involve running the above NuGet.exe, or something else? VS is telling me that the NuGet Package Manager is up to date (via the Extensions and Updates dialog), however the above NuGet.exe is quite old. I've also found a very old NuGet.exe file in C:\Program Files (x86)\NuGet\. What uses the latter, and what are the implications of these exes being out of date?
The reason I ask is that we've been having problems with a couple of solutions over recent weeks. We can't update NuGet packages - the operation fails with the message "Error: An item with the same key has already been added". I'm trying to track down the cause, and wondering if these out of date NuGet.exe files might have something to do with it.
As far as I remember this folder is useless now with the latest nuget extension to Visual Studio. It was used before and was nothing but pain in the ass. I am not 100% sure about 2013, but in 2015 all works fine without it, so my suggestion is to update to the latest available nuget extension version and try to delete the folder, most likely everything will work.
Now packages go to current user folder, and use the config from %AppData%\NuGet\NuGet.config. For NuGet 2.6 or earlier, this setting was available in a project-specific .nuget\nuget.config file.
You can read more about it here.
So nuget is gradually getting better and easy to use without too much thinking of all this "magic" folders and stuff.

NuGet Package restore for website

I am trying to use NuGet Package Restore with VS2010 + Visual Sourcesafe. It is working partially for me.
Where this is coming from: NuGet not getting missing packages
My Solution2 has asp.net website[Project1 in above image] that has another nuget package installed. Now another developer opens the Solution2 via VS2010, the automatic restore works for Library projects in Solution1. It gets all missing packages for Library projects that is referenced in this Solution2 and I see them in Solution1/packages folder.
But for Website it says external dlls i.e. pacakages missing. The issue I think is because website doesn't have a .csproj file and so it doesn't know things needs to be restored.(http://nuget.codeplex.com/workitem/1663)
Making it work partially:
Added packages/repositories.config to website solution (What is a solution folder in visual studio)
Another developer goes to VSS and get that packages folder manually. Now when he builds the solution, the Package Manager Console prompts for restore i.e. has "Restore" button. On clicking it will bring the AjaxControlToolkit.
Questions:
- Is the above approach the only and best available for Websites?
When the developer clicks "Restore" button it brings packages for Library as well to Solution1/packages along with packages for nuget. Any reason why would it do that?
Any ideas on above issues?
Per you link, nuget doesn't support websites. If you really need to use Nuget, and let's face it, everyone does, then in my opinion the best approach is to switch your website over to a web application, at which point visual studio will create a csproj file for you, detailing the nuget packages that are contained in the project.
HTH
For adding Solution level "packages" folder with repositories.config to VS Solution Explorer, I created a Solution folder and added repositories.config.
That created packages folder in the SourceSafe when I checked-in the solution.
I also found someone pointing the same thing here.
Update: I think the newer nuget is restoring the packages. But one other trick for nuget to add the dll to the bin folder it to check-in the .refresh files for AjaxControlToolkit and its dependent packages.

VS2012 Solution Open scripting or automation

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.

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.
