while getting a response from the stripe and calling the charge function() in am getting the error "Could not load file or assembly 'System.Collections.Immutable, Version=1.2.3.0, Culture=neutral" on the code mentioned below

<form action="/Pay/Charge" method="POST">
    <article>
        <label>Amount: $5.00</label>
    </article>
    <script src="//checkout.stripe.com/v2/checkout.js"
            class="stripe-button"
            data-key="@ViewBag.StripePublishKey"
            data-locale="auto"
            data-description="Sample Charge"
            data-amount="500">
    </script>
</form>

This view calls the below charge ActionResult

public ActionResult Charge(string stripeEmail, string stripeToken)
        {
            var customers = new CustomerService();
            var charges = new ChargeService();

            var customer = customers.Create(new CustomerCreateOptions
            {
                Email = stripeEmail,
                SourceToken = stripeToken
            });

//Error on this line--↓

            var charge = charges.Create(new ChargeCreateOptions
            {
                Amount = 500,
                Description = "Sample Charge",
                Currency = "usd",
                CustomerId = customer.Id
            });

            // further application specific code goes here

            return View();
        }

The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

InnerException:Null

In case System.Collections.Immutable is already installed, Check out the version of it in packages.config in case it is a different version it won't work, modify it manually to be the same version as it is logged in the exception and rebuild your solution to install the needed version.

<package id="System.Collections.Immutable" version="1.2.3.0" targetFramework="net45" />

Update:

Original question was about version 25.2.0 of Stripe.net and in that old version there was dependency on System.Collections.Immutable, howeever latest version for has no dependency on anymore:
