Describe the bug

I can not upload a file of size 500MB, 1GB or 2GB from a blazor WASM app to my asp.net core web api server.
According to this statement from Daniel Roth it should be possible.

To Reproduce

I have created a minimal working example here on githuib: Large file can't be uploaded. The code is based on this from the documentation.
I have tested with 500MB, 1GB and 2GB files. I did not add the files to the repo but I can if that is desired.
I created my test files with the following powershell commands:
fsutil file createnew Dummy500MB.pdf 524288000
fsutil file createnew Dummy1GB.pdf 1073741824
fsutil file createnew Dummy2GB.pdf 2147483648

Exceptions (if any)

I have added all browser logs in the "Exceptionlogs" folder in the above linked repo in full detail.
Exception in Edge Version 92.0.902.84 (Offizielles Build) (64-Bit)

Seems like a problem with https://github.com/dotnet/runtime/blob/cffaa78235ea93d5e3eeb56956579df503e11250/src/libraries/System.Net.Http/src/System/Net/Http/BrowserHttpHandler/BrowserHttpHandler.cs#L191-L194. We read the content into a single JavaScript array buffer. I'm not sure there's much we can do about this until fetch supports upload streaming https://web.dev/fetch-upload-streaming/

Thanks for your answers but what does that mean exactly?
Is the statement from Net 6 Preview 7 Announcement Blazor can handle large file uploads (>2GB) wrong or only applies for Server-Side?

Thanks in advance

@StefanOssendorf It applies to the InputFile component specifically.

Which in the wasm case just marshals the data from JS to C# (which on the SSB goes across the network).

If you have a large file upload request, I suggest you try and implement that using Http Ranges, not only will avoid this problem all-together, it will also be more reliable allowing you to avoid re-uploading entire files upon a failure (you would need to update only the missing chunk instead)

@javiercn Thank you for your answer.

Do you happen to have an example/information for the chunked upload? A pointer to something where this is done with an asp.net controller would be awesome since I have no experience in doing that 😅.

Thanks in advance.

@StefanOssendorf I don't have specific samples, I'm merely suggesting how I would go about it.
