I am trying to install the package Microsoft.Extensions.DependencyInjection.Abstractions in my Visual Studio 2013 solution as part of a Sitecore installation. The solution has .NET target framework 4.5.2.
The installation fails with
Install-Package : Could not install package 'Microsoft.Extensions.DependencyInjection.Abstractions 1.0.0'. 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 tried performing the installation in a completely new, empty solution but the installation still fails.
According to the link, there is a dependency to .NETStandard 1.0 but this should be supported by 4.5 according to this.
JaCraig's commment helped me solve this: I upgraded Nuget Package Manager from 2.8 to 2.12. Afterwards, there were no problems with the installation.

I am following this beginners tutorial on Microsoft's site.

In the PMC, run the following command:
Install-Package Microsoft.EntityFrameworkCore.SqlServer
When I enter that command I get these messages and errors..

This tutorial is for asp.net core 3.1.. It seems to be the one they recommend for beginners also. I am at a impass and have no idea how to proceed.
EDIT:
I think this is cus I used Visual Studio 2019 which I already had installed for Unity.. asp.net core 3.1 was the only option available for a new project... I think I need to wipe the existing server from azure, download Visual Studio 2022 and start again with a asp.net core 6 app ?
You can try to install entity framework core through the nuget package manager.
Rightclick on your project -> Manage Nuget packages. Before installing select the correct version from the dropdown for the netcore app version you are running.

FML.
I also want to point out that this tutorial is wrong. Earlier in it it says requirement is Visual Studio 2019 16.4 or later.
I did read this and checked the version of Visual studio I had installed, I met the requirements so I kept going.
In the NuGet Package Manager Console in Visual Studio Express 2012 for Windows 8, I hit
PM > Install-Package UnmanagedExports
I get the following error :

You are trying to install this package into a project that
targets'.NETCore,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 created a New Project under Visual C# as Class Library.
How to solve this issue ?
The UnmanagedExports NuGet package has an assembly in the lib/net folder inside the NuGet package. Which means it supports projects that target the full .NET Framework, any version. So it does not support UWP projects.
You would need to find another NuGet package, or find the source, if it is available, and compile that in a UWP project or a project that is compatible.
I try to install MongoDB C# official driver with Package Manager console in VS2013. It has some dependencies, and they should be installed by commands like this:
Install-Package MongoDB.Bson
But I have got such error for each package:
Install-Package : Could not install package 'MongoDB.Bson 2.4.0'. You are trying to install this package into a project that targets
'.NETFramework,Version=v4.0,Profile=Client', but the package does not contain any assembly references or content files that are compa

This is .NET 4.0 Client Profile, which Mongo driver doesn't support.
Maybe you didn't intended to use .NET 4.0 Client Profile. Go to your project properties and switch to .NET 4.5 (because it's the minimum framework version supported by the whole NuGet package).
I'm trying to install the MaxMind MinFraud package via NuGet. Whenever I try, I get the following back -
PM> install-package MaxMind.MinFraud
Attempting to resolve dependency 'System.Net.Http (≥ 4.0.0)'.

A few other similar questions here suggested restarting VS, manually adding a reference to System.Net.Http and clearing NuGet Package Cache, and changing the target framework to 4.6.2 (originally 4.5), all of which did not work for me.
Any ideas on what I can try next?
I installed this package successful in my Visual Studio 2015 Update 3 project with NuGet Package Manager 3.4.4.
So please make sure your are using the latest version of Visual Studio 2015 and NuGet Package Manager.

When trying to install Microsoft.AspNetCore.Mvc package in a .NET 4.6.1 console Application project, I get the following error:
install-package : Could not install package 'runtime.native.System 4.0.0-rc2-24027'.

Can anyone help me out ?
Basically you can not install Microsoft.AspNetCore.Mvc in a console Application. In a console application from Microsoft.AspNetCore.* you can install only Microsoft.AspNetCore.Authentication.ActiveDirectory.
To prove this try this way:
Right click in the references
Chose Manage Nuget Packages...
From 3 tabs (Browse, Installed, Updates) choose Browse tab.
Write in the search box Microsoft.AspNetCore.
The reason you can not install that your application is simply a console app not MVC structure.
