I created this package, I need it in a project but couldn't install it, this error appears:
Could not install package 'Mshwf.NiceLinq 1.0.9'. You are trying to
install this package into a project that targets
'.NETFramework,Version=v4.5', 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 don't know why this happen, in another project (Console) I changed the framework to 4.6 and other versions and it wasn't a problem, but this only happen in this project (MVC and Web API):
this is the nuspec file:
<?xml version="1.0"?>

Your package targets NETFramework,Version=v4.5.2. That means the assembly folder is lib\net452. You are trying to install the package to a higher framework (greater than 4.5) project. Create a project with framework 4.5.2 or rename the package's lib folder from net452 to the version which you want to target like net45 or net46.
You can target multiple framework too from a single package.
Edit your csproj file like this:
<TargetFrameworks>netstandard2.0;net45</TargetFrameworks>
Refer here: https://learn.microsoft.com/en-us/nuget/create-packages/supporting-multiple-target-frameworks
For a complete, up-to-date list of target framework names, refer to https://learn.microsoft.com/en-us/nuget/reference/target-frameworks#supported-frameworks
Go to the folder:
C:\Users\[username]\.nuget\packages\[package name]\1.0.0.4\lib
Rename the folder with the .net version of your project.
Suppose I am using .net framework 4.6.1 my folder name should be net461
You can install earlier version like : Install-Package AutoMapper -Version 7.0.1
The .NET Target Framework version is most likely too old. I have VS 2017 and my default Target Framework for a new .NET Framework project was 4.0. I initially tried to install the RestSharp package but it failed with an almost identical message as in this post 'Could not install package ...' However, when I went to Project | Properties | and Application I was able to change the Target Framework to .NET Framework 4.6.1 and then it installed fine.
In my case, I was trying to install the package into a WPF App (.Net Framework) while my co-workers prepared the package for .Net Core Project.
Try creating a .Net Core Project(or the type of the targeted project type) and install the packages same way:
Solution Explorer>Right click to Solution>Manage Nuget Packages for solution>Search for the needed package>Install
Checking this before other solutions may save time.
In my case, I was trying to insert a package of our own making that we put into our own Nuget feed, so I had access to the project.
This is what I did to clear the issue up. In the project solution window, click on the packages.config. In the properties window, change build action to "Content." After pushing it out to our feed again I was able to install it into the main project.
I had similar issue which i fixed by removing the packages.config(you can edit the file if you don't want to remove) file and then made sure both the package i was using was built using the same .net version as the Project i was using it in(for me the package was built using 4.6 while my console project was targeting earlier version of .net).
Update the Application .NET target framework could solve the problem. In my case, I'm installing EmguCv 4.2 package. I get this same error when trying to build with 4.5.1 .NET target framework. After updated the .NET target framework to 4.6.2, I can install the EmguCv 4.2 Nuget package successfully.
Try installing .net SDK here and then right-click on your solution/project and "restore nuget packages"
I had this problem with a package I had created and hosted on our own private nuget server, but even after trying others suggestions here such as making sure that the package supported the correct .net framework version, it still wouldn't work.
I got someone else to try and they managed to add it with no problem.
Today, messing around in VS's options, I found a fix for this:
Options -> NuGet Package Manager -> General -> Clear All NuGet Cache(s)
How to clear nuget cache in visual studio
Hopefully this helps someone who was as confused as I was :D
In my case I tried to install Itext7 package my project .NET framework was 4.5
I changed my project .NET framework to .NET 4.6.1 by using the following steps then I installed the package successfully :
1- right click the project and click properties
2- Under application tab change the Target framework to the required framework for your package
I could not install OpenTK package in .NETFramwork app but i had success with .NET Core project
Check the supported version from "C:\Users \ [username] \.nuget\packages
[package name]\1.0.0.4\lib".
Go to Project > Right click and select Properties > Application > Target Framework
Change the Target Framework to the supported version
In my case supported version is net462 for the library

If I understand Scott Hanselman's post here correctly then I should be able to reference a .net standard library from a framework 4.7.2 solution.
I want to use Nuget to install such a reference.
I am using Azure DevOps Artifacts for the Nuget package. When I push my .net standard solution I can see that the package does create and that the Nuget install command is
Install-Package SBD.Standard -version 2.0.0-CI-etc
However when I try this at the PM console for my framework 4.7.2 project I get
Could not install package 'SBD.Standard 2.0.0-etc'. You are trying to install this package into a project that targets
'.NETFramework,Version=v4.7.2', but the package does not contain any assembly references or content files that are compatible with that
framework
moreover I do not see SBD.Standard as an avialable package in the relevant feed from within VS2019 -> Manage nuget packages for solution.
I think I need packages.config
I was able to create a new 4.7.2 project and add the nuget package that used .net standard 2.0 (but not 2.1)
When I tried to add the nuget package I got a dialog asking me to select the Nuget package manager format
so I chose Packages.config and that worked.
I am not sure I have it right. I solved my problem but am not sure whether this was it after all. SInce PackageReference is more recent it should work.
Some additional explanations for this issue.
There is an issue for NuGet restore when you using new SDK-based project type or PackageReference in the .net framework:
https://github.com/NuGet/Home/issues/5461
https://github.com/dotnet/sdk/issues/1755
When we use packages.config projects or non-SDK based project type, NuGet do not check compatibility during install/restore.
So, to resolve this issue, we need make sure the referenced project is an old style csproj or use packages.config.
That the reason why the packages.config works for you.
Hope this helps.
everyone,
I downloaded the template with the following features
Abp 5.0.0.0
Asp.Net MVC 5.x
Web application with server rendered HTML; ASP.NET MVC & jQuery
Entity Framework
VS2017 Community as Development Environment
The problem lies in the Entity Framework or the version of Nuget
Running the Update-Database command from the Nuget console always returns the same error
Update-Database not recognized cmdlet
My Nuget Version is 4.9.3.5777
I tried both to clear nuget cache, restore solution packages, restart vs2017 and computer (Windows 7 Enterprise 64) without success
There is some issue on download packages?

I think this issue stands that the EF package is not installed successfully in your current project.
1.Please check if you have yellow warnings in Solution Explorer like this issue. If there's any warning, resolve it or share it here and I'll check it for you.
2.I know you've cleaned the nuget cache, but see this, there's one copy of the EF package locates in your Solution folder's packages folder when you're in project that uses Packages.config format. So though you've cleaned the nuget cache in %userprofile%\.nuget\packages, your project is still using the old copy in solutionDirectory\packages folder.
Suggestion(The order is important, please follow the steps one by one):
#1 For this, you should right-click your project=>Manage Nuget Packages(UI)=>Uninstall the EntityFramework package.(Or manually delete the EF package folder within SolutionDir\packages folder)
#2 Then clean the nuget cache by Tools=>Nuget Package Manager=>Package Manager Settings=>Clear All Nuget Cache.
#3 Close Package Manager Console if it's open. => Close VS instance.
#4 Then restart VS and reinstall that EF package by package manager UI. And manually open the Package Manager Console and type Update-Database to check if this issue goes away.
Hope it helps:)
I'm using the very latest ServiceFabric SDK (v1.4.87.9494) with VS2015 Update1 and the latest ASP.NET 5 RC1 update (v1.0.11125.0).
When I add an ASP.NET 5 WebApp to my ServiceFabric solution I am seeing an error in project.json that looks like this:
Unable to locate Dependency Microsoft.AspNet.Server.WebListener >=
1.0.0-rc1-final
I'm a super noob to ServiceFabric and ASP.NET 5, how do I go about debugging this?
This is a known (intermittent) issue that will be fixed in an upcoming SDK refresh. In the meantime, you should be able to work around it in one of two ways:
Option 1: In the web project, open project.json, make some kind of cosmetic change (add a space or a newline) and save it. This will force a package restore, which should bring down the WebListener.
Option 2: Explicitly add the WebListener package to the web project. Right-click on the web project, choose Manage NuGet Packages, then search for Microsoft.AspNet.Server.WebListener and install it.
If neither of those work, we've occasionally seen cases where having numerous NuGet package sources exacerbates this problem. You can try de-selecting all sources except nuget.org and that generally fixes it.
Add AspNetVNext to your NuGet package sources pointing to https://www.myget.org/F/aspnetmaster/api/v2/
I have a web app with a few NuGet packages. The web project targets .net 4.5. Now, one package is behaving strange. I get to download it from the official repository, but it's just not added to my bin folder.
I guess the reason is that the package downloaded contains a .dll under /net40/ folder. Adding it manually works, but NuGet is not picking it up. Is there a way I can setup this to work?
I have been using NuGet to manage my internally created assemblies for a few months, and it's working very well. I recently 'discovered' portable class libraries, which has also been great - until it's time to install the packages.
Say I have a PCL that targets .NET 4.5, SL5 and .NET for Windows Store Apps. I run nuget spec to create the .nuspec file, edit the values, package it up, and add the .nupkg to our internal feed. If I open the .nupkg file in the Package Explorer, I see one content folder under lib called portable-win+net45+sl50.
When I try to install the package from any compatible project in another solution, I get the following message:
"'Project.PCL' could not be installed because it is not compatible with any project in the solution. The package doesn't target any framework."
If I manually create the .nupkg in the Package Explorer, updating the version number, adding a lib folder for each targeted framework (not a portable folder) and added the Project.PCL.dll to each folder, I can add the package to the compatible projects in the solution. But to do this process every time I want to update a PCl is somewhat tedious (I had been creating a little .cmd file in the project root folder to quickly package and deploy).
Do other people have this problem? How can I package PCL's in the same way as other types of projects?
Note - I'm using VS 2012 Ultimate and NuGet 2.2
It sounds like maybe nuget spec doesn't work for Portable Class Libraries - that's worth starting a thread or filing an issue on the NuGet site.
However, you can also create a .nuspec file from NuGet Package Explorer. Just create the package as you already did, but then choose "Save Metadata As..." to save it as a .nuspec. Afterwards you may need to edit the source paths in the nuspec file manually, but you should be able to automate the creation of the package.
For me nuget spec and nuget pack worked fine with a portable project while creating the package and installing it on a compatible project.
Do you want to check if you have the latest nuget.exe (2.2), it can be downloaded from http://nuget.org/nuget.exe or can be updated by running nuget update -self
