Problem installing SharpPcap NuGet package in VS2015

[Terry550]

Hello,
Looking for help. I have VS2015 and DotNetFramework V4.6.1 for a new C# Project.
When trying to install the NuGet package I get the following Error:

Error Could not install package 'SharpPcap 5.4.0'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.6.1', 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've tried different frameworks but get the same error message.
Any suggestions would be greatly appreciated.
Thanks
Terry

SharpPcap targets .NET Standard 2.0, You will need NuGet client 3.6 or higher installed.
See https://docs.microsoft.com/en-us/dotnet/standard/net-standard#net-standard-libraries-and-visual-studio

If you only need to consume .NET Standard 2.0 libraries in your projects, you can also do that in Visual Studio 2015. However, you need NuGet client 3.6 or higher installed. You can download the NuGet client for Visual Studio 2015 from the NuGet downloads page.

Thank! I will give that a shot and post back to the discussion.

Installing NuGet client 3.6 worked for installing SharpPcap 5.4.0 thanks, but now I'm getting 29 duplicate reference errors when I try to build (see below). I tried editing my project file but still keep getting the errors. Do I need to uninstall something?
Thanks for any help you can provide.

Without seeing the csproj file, there is no way to tell what's going on here.
That aside, do you REALLY need to work with Visual Studio 2015?

Finally figured it out, Thanks kayoub5 for your help!!!
I found the answer on this github link
dotnet/sdk#1539

Answer: It looks like MSBuild is still adding the facades from the targeting pack. I haven't chased down the diff yet, but you should be able to workaround by setting ImplicitlyExpandDesignTimeFacades=false.
