I have created application, which is in Visual Studio 2013 update 4 and .Net framework is 4.5. Now, want to implement SendGrid for sending mail. But its giving me error like below :
The 'System.Net.Http 4.0.0' package requires NuGet client version '3.0' or above, but the current NuGet version is '2.12.0.817'.
And when I am trying to upgrade the Nuget its not showing any update(see image). Not getting what to do
