i'm trying to migrate a project into my visual studio 2012.
On the Manage NuGet Packages, I have this issue:
"Some NuGet Packages are missing from this solution. Click to restore from your online package sources"... but when i click on the restore button, it appears this issue:
"an error occurred while trying to restore packages: Unable to find version '4.1.0-alpha-121112' of package 'Microsoft.AspNet.WebApi'. "
i'm using .NET Framework 4
How can i solve?
Thanks in advance....
The problem is that version '4.1.0-alpha-121112' of package Microsoft.AspNet.WebApi does not exist on NuGet.org. It is not available on MyGet from the ASP.NET Web Stack Nightly package source either. So NuGet cannot restore it since it is no longer available.
Looking at Symbol Source it looks like this NuGet package was at one point available from the ASP.NET Web Stack Nightly package source on MyGet but it no longer seems to be available. I suspect they have deleted the old packages from that MyGet package source.
Unless you can find the original NuGet package, you will either have to manually remove the NuGet package reference, by editing the project file and packages.config file, and reinstall a version that exists.
1) Make sure you upgrade to the latest NuGet.
2) Make sure you're doing package restore "The Right Way" http://blog.davidebbo.com/2014/01/the-right-way-to-restore-nuget-packages.html
That should resolve the issue.

In my solution, I have .NET Core and .NET Framework projects. I am facing the below error (which is a .NET Core project) while compiling the solution through Jenkins:
error NETSDK1064: Package IBM.Data.DB2.Core, version 1.3.0.100 was not
found. It might have been deleted since NuGet restore. Otherwise,
NuGet restore might have only partially completed, which might have
been due to maximum path length restrictions.
The Error Message is pretty self-explanatory. Try to restore the package by either right clicking on the solution and selecting "Restore Nuget Packages" in your IDE, or run the below command in the package manager console.
nuget restore YourSolution.sln
Alternatively, you can also install the package using the below command
Install-Package IBM.Data.DB2.Core -Version 1.3.0.100
Check for any error messages while restoring or installing packages, in case there are any file path issues.
I am working on a Ubuntu 18.04 environment using Visual Studio Code and .NET Core v2.2.
After including a few existing projects into a solution that I'm working on, I ran into errors when I tried to compile stating that the namespace "Microsoft.AspNet.Mvc" could not be found.
So, I added a package reference for the projects that were complaining by using the dotnet CLI:
dotnet add package Microsoft.AspNet.Mvc --version 3.0.20105.1
But now when I try to dotnet restore or dotnet msbuild the solution file, I'm getting warnings reporting that:
warning NU1701: Package 'Microsoft.AspNet.Mvc 3.0.20105.1' was
restored using '.NETFramework,Version=v4.6.1' instead of the project
target framework '.NETCoreApp,Version=v2.2'.
This package may not be fully compatible with your project.
I would like to figure out which package version of Microsoft.AspNet.Mvc I need to install in order to be compatible with .NET Core v2.2.
I realize that this is just a warning and using the .NETFramework v4.6.1 may be okay, but I have been debugging a very strange issue that is only happening on a Ubuntu environment, so I would like to determine whether package versioning is a problem.
I have tried Google searching to determine which version of MVC is compatible with .NET Core 2.2, but I have yielded any useful results.
Does anyone know the answer to this question? Or would you be able to point me in the direction of a source that can answer it?
I have a project in .NetStandard2.0 and this has to be used as a nuget in 2 projects, one in .NetCore2.2 and the other in .NetFramework4.6.2. Installing the nuget in .NetCore2.2 had no issues, but when I'm trying to install this package in the other project, I'm getting the following error -
Could not install package 'packageName'. You are trying to install
this package into a project that targets
'.NETFramework,Version=v4.6.2', but the package does not contain any
assembly references or content files that are compatible with that
framework. For more information, contact the package author.
I also tried changing the target framework of this project from .NetFramework4.6.2 to .NetFramework4.7.2, but I'm getting the same error. Am I doing something wrong?
I had opened the Framework project in Visual Studio 2015 and this was causing the issue on trying to install the nuget package which was created in .NetStandard2.0. It was successfully installed when I tried it in Visual Studio 2017.
I'm running into an issue where I cannot install NuGet packages, or update packages, even though I have been able to install those packages in the past.
With a clean solution, I can create an ASP.NET MVC project using .NETFramework 4.5.2 (I've also tried with 4.6.1).
Since I take the default authentication options (Individual User Accounts), the Microsoft Owin packages are all scaffolded in, including the core Owin package (which is a dependency of the Microsoft Owin packages).
If I add another project (I started with a basic Class Library, but for testing purposes also tried a MVC project without authentication), I cannot add any Owin-related packages, as the Owin 1.0.0 package fails:
PM> Install-Package Owin
Attempting to gather dependencies information for package 'Owin.1.0.0' with respect to project 'Core', targeting '.NETFramework,Version=v4.5.2'

For more information, contact the package author.

The scaffolded project is using .NetFramework 4.5.2, and already has Owin version 1.0.0 working without a problem.
Similarly, Respond is included by default. The default version is 1.2.0.
I can use NuGet Package Manager to upgrade to version 1.4.1 without a problem. But if I try to upgrade to the latest stable, 1.4.2., I get the exact same errors as I do for the Owin install.
A coworker has a copy of the same project via source control, and he is also running VS2015. He can update to Respond 1.4.2. without a problem.
Another coworker duplicated every test I tried without running into any issues.
Even odder, I was able to add Owin and its dependencies to a .NET Class Library project this morning (but I couldn't upgrade to the newest Respond release). But after deleting the solution, and starting a new one, I started encountering my problems with a variety of packages.
I believe I found the solution.
I tried flushing my user cache and even uninstalling and reinstalling Visual Studio (deleting any AppData files that seemed related), but the problem persisted.
However, clearing the data in C:\Users\<<UserName>>\.nuget\packages has resolved the issue.
I'm getting the following error in NuGet while trying to install package Microsoft.AspNet.Server.IIS
Attempting to resolve dependency 'Microsoft.AspNet.Loader.IIS.Interop (≥ 1.0.0-alpha4-10330)'.
Attempting to resolve dependency 'Microsoft.AspNet.Loader.IIS (≥ 1.0.0-alpha4-10330)'.
'Microsoft.AspNet.Loader.IIS' already has a dependency defined for 'Microsoft.AspNet.FeatureModel'.
How to resolve it?
UPDATE:
Also, I'm getting the following:
Attempting to resolve dependency 'Microsoft.Framework.DependencyInjection (≥ 1.0.0-alpha4-10326)'.
'Microsoft.Framework.DependencyInjection' already has a dependency defined for 'Microsoft.Framework.ConfigurationModel'.
This was resolved by installing the latest NuGet Package Manager:
https://visualstudiogallery.msdn.microsoft.com/4ec1526c-4a8c-4a84-b702-b21a8f5293ca
Don't forget to restart Visual Studio.
I fixed a similar issue in my solution by:
Opening up a command prompt
Navigating to the .nuget folder in my solution
Running nuget update -self
This upgraded the copy of NuGet.exe that was in my solution from 2.8.0 to 3.4.4, which fixed the 'X' already has a dependency defined for 'Y' error that was stopping it from downloading SSH.NET automatically before building.
(If your solution doesn't have a copy of NuGet.exe in it - and it might not - then you should try the solution in TN's answer instead)
I tried the update, but it did not work for me. Helped:
Uninstall NuGet => Tools => Extensions and update => Installed
Install NuGet
Reload Visual Studio
I faced this error on outdated version of Visual Studio 2010. Due to project configuration I was not able to update this version to newer. Therefore, update of NuGet advised above did not fix things for me.
Root reason for the error in this and similar situations is in dependencies of the package you try to install, which are not compatible with .NET version available in your project.
Universal solution is not obligatory update of Visual Studio or .NET but in installation of older NuGet versions of the same package compatible with your system.
It is not possible to tell for sure, which of earlier versions will work. In my case, this command installed the package without any NuGet updates.
Install-Package X -Version [compatible version number]
I was getting this issue on our TeamCity build server. I tried updating NuGet on the build server (via TC) but that didn't work. I finally resolved the problem by changing the "Update Mode" of the Nuget Installer build step from solution file to packages.config.
I was getting the issue 'Newtonsoft.Json' already has a dependency defined for 'Microsoft.CSharp' on the TeamCity build server.
I changed the "Update Mode" of the Nuget Installer build step from solution file to packages.config and NuGet.exe to the latest version (I had 3.5.0) and it worked !!
Go to the link https://www.nuget.org/packages/ClosedXML/0.64.0
Search your NuGet packages
See the all version of related packages
Install the lower version of packages
In my case I had to delete the file NuGet.exe in the Project folder/.nuget and rebuild the project.
I also have in NuGet.targets the DownloadNuGetExe marked as true:
<DownloadNuGetExe Condition=" '$(DownloadNuGetExe)' == '' ">true</DownloadNuGetExe>
Hope it's helps.
The only solution that worked for me was to uninstall nuget completely from Visual Studio 2013 and then install it again with the obligatory restart of VS in between.
Go to Tools.
Extensions and Updates.
Update Nuget and any other important feature.
Restart.
Done.
In a project using vs 2010, I was only able to solve the problem by installing an older version of the package that I needed via Package Manager Console.
This command worked:
PM> Install-Package EPPlus -Version 4.5.3.1
This command did not work:
PM> Install-Package EPPlus -Version 4.5.3.2
