Please help me with the Twilio package installation in Visual Studio. I get the following error message when I try to install through NuGet manager.
Attempting to resolve dependency 'JWT (≥ 1.3.4)'. 'Twilio' already has
a dependency defined for 'Microsoft.IdentityModel.Tokens'.
thanks to all am ok now I updated the nuget manager to the latest version
I have this problem in my web service:
Specified Web Pages version “3.0.0.0” could not be found. Update your
web.config to specify a different version. Current version: “2.0.0.0”
Install Microsoft.AspNet.WebPages nuget package by entering this line in package manager console:
Install-Package Microsoft.AspNet.WebPages -Version 3.0.0
Or find and install it using Nuget Package Manager.
Go to the Nuget Package Manager in Visual Studio Code. Search for Microsoft.AspNet.WebPages and update this package if you already have the latest one the you should try to downgrade one version previous.
Or
You can run the below command in Package Manager Console in Visual Studio:
Install-Package Microsoft.AspNet.WebPages
This will resolve the issue.
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 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:

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
I am working on an ASP.NET project in which I need to do simple HTML templating.
The prettiest solution seems to be RazorEngine, which depends on Microsoft.AspNet.Razor. However, when trying to install Microsoft.AspNet.Razor via Nuget, the following error message is shown:
Installing 'Microsoft.AspNet.Razor 3.0.0'. Successfully
installed 'Microsoft.AspNet.Razor 3.0.0'. Adding
'Microsoft.AspNet.Razor 3.0.0' to EBulkDBSManagementApp.
Uninstalling 'Microsoft.AspNet.Razor 3.0.0'. Successfully
uninstalled 'Microsoft.AspNet.Razor 3.0.0'. Install failed.
Rolling back... Could not install package
'Microsoft.AspNet.Razor 3.0.0'. You are trying to install this package
into a project that targets '.NETFramework,Version=v4.0', 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.
Any solution?
The latest RazorEngine 3.4.0 NuGet package depends on the Microsoft.AspNet.Razor 3.0.0 NuGet package which requires .Net 4.5
If you wish to use RazorEngine with a version of .NET prior to 4.5, then you will need to use the RazorEngine 3.3.0 NuGet pacakage.
You can install this using the package manager console with the following command.
Install-Package RazorEngine -Version 3.3.0
