Error on 'Ext.NET.MVC 3.2.1' installation,using Packet Manager Console

[nasim]

I've changed my visual studio to 2015 and I'm using .NET Framework 4.6 in my project,when I use 'Install-Package Ext.NET.MVC' command in Packet Manager Console to upgrade Ext.NET.MVC dll from 2.5.3.1 version to the latest one, It makes changes up to somewhere then an error occurs and rollbacks all to the previous version. It is almost 2 days that I have tried everything, but nothing have happened yet. Please somebody help me !

This is what I get in my console:

Hi Nasim,

I do not quite have any ideas what is going wrong.

I've changed my visual studio to 2015

From which one? I guess VS 2013? But anyways it is better to exclude guesses.

I'm using .NET Framework 4.6

Was it 4.6 before the migration to VS 2015?

in my project

Is it reproducible with an empty MVC project created via Visual Studio New Project Wizard?

By the way, what is MVC version?

So, please describe the steps to reproduce the issue in a little greater details. Some set of exact steps would help a lot.

Hello Daniil.
Thanks for your reply.
Actually I've started a new project at home, so I have tried to add EXT .Net dll to an empty MVC project, and I've moved from VS 2010 to 2015.In addition, my .NET Framework was 4.5 before migration to VS 2015. and my MVC version is 5.2.3.0.

By the way, I should say that I've tried Web Application instead of MVC, I got the same error when I wanted to add Ext .Net dll for web apps!

Thanks for your help in advance.

I am sorry for the delay in answering. I overlooked your response.

I tried something, but could not reproduce the issue.

A detailed list of exact steps to reproduce the issue from scratch would be much appreciated. Like:

1. Do that
2. Do this
...

Actually there were no special steps. I created a new project then I executed the latest Ext command in Nuget console in order to have Ext dll in my new project. But I got this error in every time that I tried to download directly the latest version of EXT. but later I solved the problem with first downloading the 2.5.1 version and then updating it to the latest one.
Thanks Daniil.
