I have a C# solution targeted for framework 4.5.1 but the server I need to install this on uses 4.0 so I need to roll this back.
The developer has used NuGet (which I'm not really familiar with) for dependency management. I've seen there is a way to request specific versions of each library so I'm hoping there is a feature which allows me to restrict these to a specific .NET version.
How can I get NuGet to install the latest dependencies for .NET version 4, or is this not a feature it supports?
If you change the target framework of the project then Visual Studio will check the compatibility of the NuGet packages and tell you which ones are compatible or not and whether they need to be reinstalled. You can then reinstall them from the Package Manager console using the -reinstall option.
Update-Package –reinstall <packageName>
NuGet does not directly support a way to restrict or install NuGet packages for a specific .NET version. The NuGet package will either support that .NET version or not. You can restrict a project to a specific version of the NuGet package by using the allowedVersions attribute in the packages.config file but that is independent of the .NET version the NuGet package supports.
Nuget should install packages that are available for the targeted version of .NET
Check your packages folder, or check the documentation of each dependency for support of .NET 4.0
In some cases you may just be able to re-target your application without uninstalling any Nuget packages.
To install a specific version of a Nuget package, you can use the "-Version" flag
Example -
Install-Package AvalonDock -Version 2.0.1320

How install packages in Net 5.0 runtime of local (or remote) computer, so that will be available for all projects I create, without add explicitly to each project with nuget ?
Ideally each package installed in this way should be reachable just declaring it's namespace.
Example:
the package is Microsoft.Extensions.Configuration.Json
install this way the package
create a console .net application, and I do not add nuget package
use package classes just declaring "using Microsoft.Extensions.Configuration"
Hope there is a way to do this
This can't be done. It would quite quickly become unusable when different projects needs different versions of these packages (like when you start a new .Net 6 project in the future and all old projects want the .Net 5 assemblies).
What you could do however is to create your own meta package with your default list of packages, that way you would only need to install one package to your new projects which would then include all the ones you want.
How to create meta package (package of all packages) like Microsoft.AspNetCore.All in nuget?
I am trying to install System.Runtime.Handles so I can use SafeAccessTokenHandle and RunImpersonated, however when I try to install the package I get the error :
Could not install package 'System.Runtime.Handles 4.3.0'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.5.2', 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 have done some research and I do not believe there is a .NETFramework, Version=v4.3.0. Does anybody have an idea on how to install this package?

First, you have to make sure the version of NuGet Package Manager for Visual Studio 2013 is the latest version 2.12.0.817, not the default version 2.8. You can check it from Tools->Extensions and Updates->Installed.
That because this nuget package require the NuGet 2.12 or higher.
Second, you should make sure you have installed the .net 4.6 and above. You should not change the framework version by unloading the project, opening the project file, changing the target framework, and then reloading the file. In this way, Visual Studio can not help to check if you have install that target framework. You should change it by right on the project select Properties->Application->Target framework:
If you do not have target framework .net 46, you can click the Install other frameworks to install it. For this question, you can just change your target framework to 4.7.1 directly.
Hope this helps.
I am trying to install NuGet package MPI.NET 1.3.0 to MS Visual Studio 2017 C# project. I am getting the following error:
Could not install package 'MPI.NET 1.3.0'. 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.
I have tried to create C# projects in different versions of .NET Framework, but it would not install. On the official GitHub site for this package (MPI.NET GitHub repository) it is written that the package is updated for .NET 4.0. I have tried creating 4.0 and lower projects, but no success.
Help anyone?
Looking at the packages available on nuget.org, version 1.3.0 targets .NET 4.6.2, whereas version 1.2.0 targets .NET 4.0. So if you try to install version 1.2.0 of the package into your project, you should be okay. It sounds like the GitHub documentation needs to be updated to reflect this new reality.
(Personally I would bump the major version number for a change like this, given that it's not necessarily backwardly compatible for existing users, but semantic versioning is less cut and dried than it sometimes sounds.)
Does anybody knows which Nuget package contains Microsoft.VisualStudio.LanguageServices.CSharp.dll?
This DLL should be part of the Roslyn project e.g.:
http://sourceroslyn.io/#Microsoft.VisualStudio.LanguageServices.CSharp/CodeModel/Interop/ICSAutoImplementedPropertyExtender.cs
but it looks like it is not installed either in Microsoft.Net.Compilers 2.3.0 or in Microsoft.VisualStudio.LanguageServices.
Thanks in advance.

MSDN says it is located in the Microsoft.VisualStudio.Package.LanguageService.14.0 assembly.
This link should also be helpful:
.NET Compiler Platform ("Roslyn") support for Visual Studio.
Supported Platforms:
.NET Framework 4.6
To install Microsoft.VisualStudio.LanguageServices, run the following command in the Package Manager Console:
Install-Package
Microsoft.VisualStudio.LanguageServices -Version 2.2.0
I believe it is contained within a Nuget package called Microsoft.VisualStudio.LanguageServices.
Instructions on how to install the package, as quoted from https://github.com/dotnet/roslyn
To install the latest release without Visual Studio, run one of the
following nuget command lines:
nuget install Microsoft.Net.Compilers # Install C# and VB compilers
nuget install Microsoft.CodeAnalysis # Install Language APIs and
Services
I am trying to add System.Reactive.Core to a .NET 4.0 project using VS2013 and getting the following error:
Could not install package `System.Reactive.Core 3.0.0`.
You are trying to install this package into a project that target
`.NETFramework,Version=v4.0`, but the package does not contain any assembly
reference or content files that are compatible with that framework.
I also cannot find the old Rx-Main packages anymore on nuget.org.
How can I get Rx Installed on .NET 4.0?
I guess I will have to manually go find the RxMain 2.x libs and reference them directly from a lib folder in my solution?
Ok I figured it out, Rx-Main has been unlisted, therefore can only install it using the following command:
Install-Package Rx-Main -Version 2.2.5
To Rx Team: You should of recreated 2.2.5 System.Reactive which allowed us to target .NET 4.0 before moving up to 3.0.0.
