ReadAsync dont work when Release

[lulikin]

function
public Task ReadAsync(byte[] buffer, int offset, int count)
works correctly, when I'm in debug mode, but when I'm in release mode or when I publish blazor web assembly project, that function always return 0.
Here is my code :
```
var fs = await files.FirstOrDefault().OpenReadAsync();
Console.WriteLine(fs.Length);
byte[] data = new byte[fs.Length];

        long filepos = 0;
        _IsProgressOpened = true;
        byte[] buffer = new byte[1024 * 10];
        using (MemoryStream ms = new MemoryStream())
        {
            int read;
            while ((read = await fs.ReadAsync(buffer, 0, buffer.Length)) != 0)
            {
                filepos += 1024 * 10;
                progresval = (int)(filepos * 100 / fs.Length);
                StateHasChanged();
                ms.Write(buffer, 0, read);
                Console.WriteLine("Buffer length " + read);
            }
            Console.WriteLine("File uploaded");
            service.Motive = ms.ToArray();
            Console.WriteLine("File length : " + service.Motive.Length);
            service.MotiveOriginalFileName = originalfilename;
        }
        _IsProgressOpened = false;
        StateHasChanged();

**Expected behavior**
Function should work.

**Project type**
Client side

**Environment**
 - Browser: doesn't matter
 - Version of Blazor.FileReader: 1.2.0.19363
 - Version of .net sdk: 3.1.100

Sounds like a framework bug but sounds can be deceiving. Ill try to find the time to reproduce in the coming days.

Could you create a small project that reproduces this? Or at least post your full setup? Your setup could possibly affect this - there has been some issues in the framework regarding static resources and release/publish

Try the solution in #97 and see if this works for you

Thought it sounded familiar

I can't reproduce this. Please provide a full repro project.

I changed code. It was working till now (Blazor 3.2)

var x = fileReaderService.CreateReference(inputTypeFileElement);
        var files = await fileReaderService.CreateReference(inputTypeFileElement).EnumerateFilesAsync();
        var originalfilename = await jsRuntime.InvokeAsync<string>("getFileNameFromId", inputTypeFileElement);
        if (true)//(files.Count() == 1)
        {
            this.StateHasChanged();
            //var fs = await files.FirstOrDefault().OpenReadAsync();
            //Console.WriteLine(fs.Length);
            //byte[] data = new byte[fs.Length];
            //long filepos = 0;
            _IsProgressOpened = true;
            //byte[] buffer = new byte[1024 * 10];

            service.Motive = (await files.FirstOrDefault().CreateMemoryStreamAsync()).ToArray();
            service.MotiveOriginalFileName = originalfilename;

            //using (MemoryStream ms = new MemoryStream())
            //{
            //    int read;
            //    while ((read = await fs.ReadAsync(buffer, 0, buffer.Length)) > 0)
            //    {
            //        filepos += 1024 * 10;
            //        progresval = (int)(filepos * 100 / fs.Length);
            //        StateHasChanged();
            //        ms.Write(buffer, 0, read);
            //    }
            //    service.Motive = ms.ToArray();
            //    service.MotiveOriginalFileName = originalfilename;
            //}
            _IsProgressOpened = false;
            StateHasChanged();
        }

Now I have problem with 'Blazor.platform.findMethod' in javascript, but I see, that this promlem is beeing investigated in another thread.

I'm closing this as the original issue is resolved
