Cross Domain Web API: Install-Package Microsoft.AspNet.WebApi.Cors Not Working

Question

As Cross Domain call to Web API project not working from ASP.NET Web Forms client in IE (Working in other browsers). I guess I need to install following Nugget pakage.

Install-Package Microsoft.AspNet.WebApi.Cors

But when I try to install it I got following error.

Install failed. Rolling back...
Install-Package : Could not install package 'Microsoft.AspNet.WebApi.Client 5.1.2'. You are trying to install 
this package into a project that targets '.NETFramework,Version=v4.0', but the package does not contain any as
sembly references that are compatible with that framework. For more information, contact the package author.

I am trying to install in: Visual Studio 2010 which targets .NET 4.0.

Does this package is not supported in .NET 4.0 ?

Best Regards Hardeep

Answer 1

.NET 4.5 is a minimal requirement for 5.0 version and above of Web API.
