In order to cleanse the data as we parse it, we thought using a try/catch would be ok. If we don’t catch the exceptions, we’re good, right?
Turns out it kills our performance when we throw a lot of exceptions, even if we don’t catch them. Each exception has some costs . We needed to find a way to handle this data without involving exceptions.
TryParse turns out to be a method designed to solve our problem. We ran some benchmarks to prove it.
In .NET 8 we plan to add a new project template, Blazor
Web Application, that covers all combinations of server-hosted projects
(traditional Blazor Server apps, Blazor WebAssembly hosted, and the new
unified architecture that allows use of Server, WebAssembly, and SSR in a
single project). It will work by multitargeting over net8.0
and net8.0-browser
.
We are excited to announce the open-sourcing of Microsoft GW-BASIC on GitHub!
Yes, seriously 😀
