Failed to install package "Microsoft.Owin.Security 2.0.1"

Question

Failed to install the package "Microsoft.Owin.Security 2.0.1". You are trying to install this package in a project that targets ".NETFramework, Version = v4.0", but the package does not contain assembly references or content files that are compatible with this infrastructure. For more information, contact the author of the package.

What do I need now? ...

thanks in advance.

This means that they created the nuget package, which contains only assemblies intended for other versions of the framework, for example Framework 4.5

4.0, nuget :

Install-Package Microsoft.Owin.Security -Version X.X.X

X.X.X - .

http://www.nuget.org/packages/Microsoft.Owin.Security

Visual Studio 2012/2013 , Framework 4.5, .
