This upgrade may help fix and improve this issues but this may require to upgrade to NET5, it seems worth for blazor wasm to increase download speed in a exponential way.

This is now a breaking change in .net 6.0 - https://docs.microsoft.com/en-us/dotnet/core/compatibility/aspnet-core/6.0/byte-array-interop

You get the following error:

I will try take a look how to upgrade this with backward compatibility.

Hello @arivera12, I'd recommend skipping .NET 5 and going straight to .NET 6 in this case as .NET 6 has significant improvements to the byte array interop mechanisms.

Blazor no longer Base64 encodes/decodes byte[], and also natively supports streaming via JSStreamReference/DotNetStreamReference. This'll provide SIGNIFICANT improvements to stability and performance over .NET 5 in this area.

@TanayParikh yes this is a huge performance boost.

I see people having issues at this moment with net5 and net6.

I will try separate a space on the weekend to upgrade this with backward compatibility
