QUIC is a general-purpose transport layer network protocol proposed as the replace- ment for TCP and TLS in HTTP/3. QUIC is based on UDP and provides always- encrypted connections able to transmit multiple streams of data in parallel. Compared to TCP, QUIC promises lower latency, better congestion control flexibility, and a solution to head-of-line blocking occurring in multiplexed HTTP/2 connections. The latest release of .NET - .NET 5 - has shipped with experimental support for QUIC based on the MsQuic C library. However, when implementing new features in stan- dard .NET libraries, purely .NET implementations are preferable to adding dependencies on native libraries because .NET implementations offer better maintainability and - in some cases - even better performance. This thesis explores the viability of a purely C# QUIC implementation as a future replacement for .NET 6 or later release. This thesis's result is a fork of the official .NET runtime repository with partial C# implementation of the QUIC protocol. We implemented a subset of the QUIC speci- fication, which is sufficient for a basic performance evaluation. As part of the thesis, we have benchmarked the throughput and latency of our and the MsQuic-based QUIC implementation and compared them to TCP's performance in two environments: LAN and...
