I'm trying to add AutoMapper as a dependency to a project using NuGet on Visual Studio Premium 2012, but it fails.
It says:
Operation failed
'AutoMapper' already has a dependency defined for
'Microsoft.CSharp'.
I'm able to add other dependencies.
I'm using the last version of the package manager for VS 2012:
NuGet Package Manager 2.8.60318.667
Any ideas what should I check?
The problem is that your NuGet Package Manager is too old. You need NuGet 2.12 since this supports the newer .NETStandard frameworks that the AutoMapper 5.0.1 NuGet package is using.
The AutoMapper has a group dependency which specifies a target framework of .NETStandard. Since your version of NuGet Package Manager is too old it does not recognise this target framework and converts it to an Unknown target framework and you end up with duplicate frameworks since there .NETStandard is used a few times in that NuGet package. This causes the error:
'AutoMapper' already has a dependency defined for 'Microsoft.CSharp'
Unfortunately NuGet 2.12 is not available for Visual Studio 2012 but is available for Visual Studio 2013.
So either you need to update to Visual Studio 2013 or above, or you will have to use the older AutoMapper NuGet package which does not support .NETStandard.
Seems to be a problem with the current version of automapper:
AutoMapper 5.0.0 Tuesday, June 28, 2016
I tried with the previous version and it works:
PM> Install-Package AutoMapper -Verbose
Install-Package : 'AutoMapper' already has a dependency defined for 'Microsoft.CSharp'.
At line:1 char:16
+ Install-Package <<<< AutoMapper -Verbose
+ CategoryInfo : NotSpecified: (:) [Install-Package], InvalidOperationException

PM> Install-Package AutoMapper -Version 4.2.1
Installing 'AutoMapper 4.2.1'.
Successfully installed 'AutoMapper 4.2.1'.
So, if you can't update NuGet Package Manager, the answer is:
PM> Install-Package AutoMapper -Version 4.2.1
I ended up needing to update NuGet.exe that was included in the solution to be able to build NuGet packages by running:
nuget.exe update -self
I had the same issue on VS2013. I had to update to VS2013 Update 5 and get the latest nuget distro for VS2013 at
https://dist.nuget.org/visualstudio-2013-vsix/v2.12.0/NuGet.Tools.vsix
Once that was done, I rebooted Visual Studio. After that I was able to use the Automapper 5.0.2 package
Go to Visual Studio > Tools > Extension and Updates
Find Updates in left accordion menu, Go to Visual Studio Gallery.
You will find a update for Nuget.
Update the nuget package and try installing or builing the project.
Thanks,

An other workaround if you're stuck with VS2012 and the old Nuget version:
Find the Cache folder of VS 2012's Nuget Package Manager (with Tools - Options - Nuget Package Manager)
Open AutoMapper.5.x.x.nupkg with your favorite Zip Tool
Modify the file AutoMapper.nuspec - I simply deleted all dependencies except .NETFramework4.5
Add the cache folder as a Nuget source (also in Tools - Options - Nuget Package Manager)
Install Automapper either with the console or the GUI but make sure to choose first the newly added cache folder as package source.
Of course, the next version of Automapper probably needs to be adapted, too, in order to install it.
This looks like a mismatch between the .NET version used by the Automapper package and your project. Can you confirm the .NET version that your project is using?
Automapper 6.0.2 - nuget 2.8.8 gives this error. Needed to update to 3.4.4 to get this working.
Removed both CSharp and AutoMapper. Installed CSharp (4.0.0.0) first and then added Automapper (6.1.1.0). This resolved the problem for me.
I observed this exact problem when opening a project with Visual Studio 2010.
After opening with VS2017, I was able to install AutoMapper without any error.

having spent the better part of two days on this, time to get some help.
I am reworking our CI build, and have a VS2017 solution which was on .net 4.6.1, using packages.config style nuget refs, and TeamCity was using the NuGet runner v3.4.4 to restore the packages. It was originally build probably using VS2008 or 10, then converted to 2017 in 2018. Someone checked in the packages directory and it's been that way for years.
Time to bring it up to more modern standards. I converted the projects to use packageReference, and now am using msbuild and the restore;build target to restore my packages and build the solution. Works well EXCEPT for this one package.
Even in VisualStudio 2017 15.8.7, the build (which does the restore of course) is failing to restore the smtp-impostor package using a packageReference with the following error:
NU1202: Package smtp-impostor 2.0.8 is not compatible with net461 (.NETFramework,Version=v4.0). Package smtp-impostor 2.0.8 supports: netframework40 (.NetFramework 4.0,Version=v0.0)
I can't get Google to find a single useful post when searching for "netframework40".
If I use nuget3.4.4 CLI, it works fine (it seems to call msbuild 4.0). If I use nuget 5.6 CLI, I get the error message; it's using the msbuild that comes with Visual Studio 2017.
I see a lot of posts on how to get nuget to use a different version of msbuild, but I don't see how to tell msbuild to use an earlier version of nuget!
I have tried:
retargeting the solution to v4.0 - same error occurs - first part of error just changes to net40
setting the ToolsVersion in the csproj file tag to 14.0
Setting the PlatformToolsVersion property in the csproj file to 14.0.
No dice.
I really don't want to stay with packages.config for this project (and an extra CI build step) nor checkin the single DLL for the package into my repo. It's looking more like I'll jsut have to scrap the packageReference upgrade and stick with the old style nuget runner package restore.
Anyone ever seen this? Any ideas where "netframework40" comes from and why newer nuget can't match it with net40?
Thank you in Advance!
Newer versions of NuGet.exe can't resolve framework match when
restoring older packages (net40, netframework40)
The issue is that this nuget package smtp-impostor 2.0.8 is not compatible with the new PackageReference format and has nothing to do with Nuget V3.4.4 or Nuget V5.6.x.
Actually, the package was published on 2011 and the new package management format PackageReference was used since VS2017.
Besides, the author did not make any changes to the package to accommodate the new Packagereference. And I faced the same issue in my side.
Suggestion
As a workaround, you have to use packages.config to install this nuget package rather than PackageReference.
Since VS2017, VS adds the new PackageReference nuget management format and for your old VS2008, it uses Packages.config.
Or you could contains the author of the nuget package to change it.
I am trying to build a web site using .net framework core with entity framework core. I created a web project using the ASP.NET Core Web Application (.net core) template with Visual Studio 2015 Professional (update 3). Then I used Nuget to add the Microsoft.EntityFrameworkCore.Tools to the solution.
When I compiled the solution, I got this dependency error - "NU1001 The dependency Microsoft.EntityFrameworkCore.Tools >= 1.0.0-preview2-final could not be resolved". I googled the topic but couldn't find the solution. How can I fix this??
For those who may run into this problem, you would need to right click on the References and click Restore Packages. That solved the problem.
Have you added the following nuget Packages sources in your nuget package?
https://dotnet.myget.org/F/aspnetcore-ci-dev/api/v3/index.json
You can do so in Tools > Nuget Package Manager Settings > Packages sources
Also, what is your SDK version?
It should be "1.0.0-preview2-003131".

I had the same problem, this work for me:
Install-Package Bootstrap
"As of v3.0.1.1 the Twitter.Boostrap package will begin redirecting users to the Bootstrap package managed by the Outercurve foundation. The reason for this move is pretty simple. Bootstrap is a cleaner namespace since the project dropped the twitter name a few releases ago and Bootstrap now officially ships with the Visual Studio 2013 ASP.Net templates. So to avoid confusion on which release is "official", we've agreed to redirect everyone over to the new Microsoft maintained namespace."
http://chriskirby.net/bootstrap-nuget-package-moving-to-outercurve/
https://github.com/sirkirby/twitter-bootstrap-nuget/issues/22
I encountered the same error with both VS 2010 and VS 2012. The suggested solution did not solve the problem, but I did notice that the NuGet Package for Bootstrap is dated Nov 1, 2013 (yesterday). The new package has version number 3.0.1.1 and it lists a dependency of Bootstrap version 3.0.1 or higher. It appears there is an error in version 3.0.1.1 of this package with a circular reference in the dependency. Look for version 3.0.1 by the same authors.
I am assuming you are using Visual Studio 2012. In VS2012 new MVC4 projects are loaded with jquery 1.7 by default. But Bootstrap 3.0.1 has a dependency on jquery 1.9 or higher
So first run
update-package jQuery
and then
install-package twitter.bootstrap
I had the same problem. After I updated NuGet Manager, it solved by problem. To update NuGet Manager, you can to Tools -> Extensions and Updates
I had the same problem when installing Bootstrap 3.0.1.1. It does look like it is looking for 3.0.1 for its dependency. I at the end installed 3.0.0 with no problem.
I had this same problem that brought me to this question. In Package Manager I searched for bootstrap and there were several results returned.
I clicked on the on at the top of the list and tried to install this one (version 3.0.1.1) and received the error reported in the original question. The ID of this package is Id: Twitter.Bootstrap
There was another Bootstrap package listed with version 3.0.2 with Id: bootstrap
I installed the second one v. 3.0.2 and this installed without any issues.
Taken from fontawesome:
"The folks at Outercurve have taken over support for the Twitter.Bootstrap package now being called simply bootstrap.
More info here http://chriskirby.net/bootstrap-nuget-package-moving-to-outercurve/"
It would seem to me that the redirect to the new Microsoft maintained namespace is causing this to happen.
My Problem perfectly solved
Try
Install-Package Bootstrap
Instead of
Install-Package Twitter.Bootstrap

Just try update vs2012 !I resolved it!
I updated VS2012 to VS2013. It resolved the problem
I also had the same issue. But resolved when updated the Nuget Manager and tried again after that.
I have recently installed the Latest Win8 OS (RTM) and installed MSVC 2012 RTM as well (I also have MSVC 2010 installed as I am porting from Win7 Phone to Win 8 Tablet and need to refer to the old code (not sure if this may affect outcome)). I need to install Entity Framework in MSVC 2012 and when I look at the NuGet Package Manager it tells me version 5.0.0. is available. However it never installs correctly, it says it has installed successfully then, says it can't and uninstalls it. I have tried using the NuGet Package Manager and the PM console, the results from the PM console are below :

What is going wrong? pls help.

You are adding EntityFramework package to Windows 8 Application or class library project (= to Metro application). That is not supported. You must use full .NET Framework 4.5 (= desktop application, web application, etc.) to use Entity Framework.
I had this problem. This is what I did:
From the package manager console:
PM> Uninstall-Package EntityFramework -Force
This threw an error. I then went to the "packages" folder under the solution folder and removed the Entity Framework subfolder. I then ran
PM> Install-Package EntityFramework
And then right-clicked my project where I wanted to install EF and installed it from the NuGet dialog.
I am trying to use NuGet to add SignalR and Raven to a new ASP.Net MVC 4 project.
If I do SignalR first, then try to add Raven I get the following error:
Install failed. Rolling back... Install-Package : Already referencing
a newer version of 'Newtonsoft.Json'.
If I install Raven first, then SignalR I get:
Install failed. Rolling back... Install-Package : Updating
'Newtonsoft.Json 4.5.7' to 'Newtonsoft.Json 4.5.8' failed. Unable to
find a version of 'RavenDB.Client' that is compatible with
'Newtonsoft.Json 4.5.8'.
I thought NuGet was meant to handle this sort of thing?
How can I get them both added?
It appears that RavenDB.Client has an exact-version constraint on Newtonsoft.Json = 4.5.7, while SignalR has a more relaxed constraint of '4.5.4 or higher' (actually a constraint imposed by one of its own dependencies, SignalR.Server).
I managed to get your above scenario working with some manual tweaking:
Created new MVC4 project
Opened up packages.config and added an 'allowedVersions="[4.5.7]"' attribute to the Newtonsoft.Json package entry
Opened the package manager console (View... Other windows... Package Manager Console) and ran update-packages to pull in latest code for all default dependencies (takes a while)
Again in package manager console, ran install-package RavenDB.Client
Finally in package manager console, ran install-package SignalR
I tried a few combinations of ordering the above but it wasn't liking it - the thing that let it work seems to be the manual editing of packages.config to lock the version of Newtonsoft.Json to 4.5.7 so that subsequent installs don't trash the referenced version.
We ran into this exact issue, but ultimately pulled in the Raven assemblies manually (so we could target a specific version).
Something that we came across is that it is possible to force Nuget to install a package using the command line tools:
How to install an older version of package via NuGet?
I ran into the same issue, but instead decided to install an older version of SignalR. Version 4.0 (February 2012) has a dependency on NewtonSoft >= 4.0.7, and this installs correctly with RavenDB already installed:
Install-Package SignalR -Version 0.4.0
I got the same problem with Raven and the standard MVC template. I wanted the latest version of Newtonsoft.Json so I solved it differently.
I checked what dependencies RavenDB Client had and then installed the latest version of them first Newtonsoft.Json and NLog
I then installed the packet in the Packet manager Console with the -IgnoreDependencies flag.
Install-Package -Id RavenDB.Client -IgnoreDependencies
That worked fine. (I am taking a calculated risk that RavenDB is not compatible with the latest Newtonsoft.Json at the moment. But I am a Daredevil)
