Error while downloading Unity IoC container from Nuget

Question

I am building a console application for the sake of Inversion of control. I have tried to download "Unity" IoC container from nuget package manager, but got this error. Any help is useful. I am using visual studio 2010 pro.

Answer 1

It looks like you are using .NET Framework 4 and trying to add Unity 3. In the documentation of Unity 3 it says:

System Requirements Supported architectures: x86 and x64.

Operating systems: Microsoft Windows 8, Microsoft Windows 7, Windows Server 2008 R2, Windows Server 2012.

. NET Framework: Microsoft .NET Framework 4.5, .NET for Windows Store Apps (previously known as Windows Runtime)

To use Unity in .NET 4 you need to use this package instead:

Install-Package Unity -Version 2.1.505.2

Answer 2

From unity.codeplex.com .

System requirements Supported architectures: x86, x64, ARM. Operating systems: Microsoft Windows® 8, Microsoft Windows® 7, Windows Server 2008 R2, Windows Server 2012, Windows Phone 8. Supported .NET Frameworks: Microsoft .NET Framework 4.5 , .NET for Windows Store Apps (previously known as WinRT), .NET for Windows Phone. Rich development environment: Microsoft Visual Studio 2012, Professional, Ultimate, or Express editions.

So yes, use older version.
