Excel Read Differences between .net Core & .net Framework (Epplus)

Question

I want to take an Excel file form the user and want to read it. I can do it on .net Core project with the first code block below as you see. But I have to run it on a .net Framework project now. I have to fix 2 parts. First one is IFormFile comes with AspNetCore.Http.Features package. How can I take the file in .net Framework in sameway? Second one is await file.CopyToAsync(stream); code block. How I can work it on .net Framework project? Rest of the code is OK I guess.

public void ExcelProducts(IFormFile file)
{
    using (var stream = new MemoryStream())
    {
        await file.CopyToAsync(stream);
        using (var package = new ExcelPackage(stream))
        {
            ExcelWorksheet worksheet = package.Workbook.Worksheets[0];
            var rowcount = worksheet.Dimension.Rows;
            for (int row = 2; row <= rowcount; row++)
            {

                try
                {

...
}

And this is my View.

<div class="text-center">
    <div class="container">
        <form method="post" action="Market/ExcelProducts" enctype="multipart/form-data">
            <input type="file" name="file" />
            <button type="submit">Submit</button>
        </form>
    </div>
</div>
