After about a year of back and foth, my OpenTelemetry PR to enable #webassembly support .NET finally got through! The original code was using threads, and it's now using tasks on Wasm, allowing for Azure App Insights to work in Blazor and @platform.uno scenarios. github.com/open-telemet...

What's happening with Uno now that .NET 10 is released? @jlaban.bsky.social and @samidip.bsky.social talk on .NET Rocks at www.dotnetrocks.com/details/1984 about the latest developments in Uno, including the collaboration with Microsoft on MAUI, WASM, and more!

Now I can watch #dotnetconf! Three years in a row of presenting at the conference makes me watch all sessions a few days later. Worth every bit of it!

Getting ready! Join in to see all the new fancy MCP features! #dotnetconf

This is a big release! We've been hard at work for building those new AI integrations, and it's supercharging the dev cycle for uno apps. AI Agents have made a LOT of progress in the past months and we're eager to see what you will do with our MCPs! Let us know what you think! #dotnetconf

VS 2026 Insider is available! Among many other changes, one not so obvious change in that release is the default to `.slnx` format, and the good news is that @platform.uno supports it out of the box! devblogs.microsoft.com/visualstudio... #dotnet

Visual Studio 2022 v17.14 Preview 2 is out: learn.microsoft.com/en-us/visual... 17.14 is focused on on stability/security/AI. Just the VS Editor team alone fixed 50+ high priority bugs and feedback tickets. You can also now use GPT-4o model to get smarter Copilot completions ("gray text").

New release of MSBuild Structured Log Viewer. New dark theme which should be much faster (don't laugh). Turns out the old dark theme we used (AdonisUI) messed with the tree view virtualization, so we saw significant slowdowns in tree layout.

The next #UnhandledException podcast episode has dropped! I was joined by @jlaban.bsky.social to chat about the Uno Platform and an awesome new feature called Hot Design! The podcast is available on all major podcast platforms. unhandledexceptionpodcast.com/posts/0074-u... #dotnet @platform.uno

Attention .NET fans! .NET 10 Preview 1 is now available: github.com/dotnet/annou...

Sorry there's been a gap since the last podcast episode, but now getting back into it again! Have just recorded the next episode with @jlaban.bsky.social where we chatted about the Uno Platform, and a pretty jaw-dropping new upcoming thing called Hot Design! @platform.uno #dotnet #UnhandledException

The VS team has been super responsive lately, particularly on WSL issues. We were battling with the "first-tfm-wins" kind of issues that prevented WSL from starting in #unoplatform projects. There's a new project cap that works without tricks in 17.13 Previews! Thanks! #dotnet

@madskristensen.net would you know if there are docs for extension authors on how to troubleshoot VS messages like "VS stopped responding, disabling the extension XXX might help"? I know you receive telemetry on this, but is there something we can do externally? Thanks!

@platform.uno worked really hard on these optimizations and you can immediately see and feel the improvements.

🚀 First Release of 2025! We're doubling down on productivity and performance for cross-platform app development! ⚡Perf: 2.5x faster: Wasm AOT, leaner memory use 🔥 Hot Reload: Supercharged for Mobile scenarios 📦 Automated App Packaging: New formats (.pkg, .dmg), code signing, and notarization.

The State of WebAssembly 2024—2025 ⤵️ platform.uno/blog/state-o... #webassembly #wasm

Back home from @codemash.bsky.social! I met a lot of cool people, caught up with some old friends, and spoke a lot about @platform.uno :) Catch my recap here: kazo0.dev/conference/2...

Sweet! I just got upgraded to the in-person #mvpsummit! I hope to see many of you there! Last year was amazing! #dotnet #mvpbuzz

Hu ho, the #dotnet 9.0.102 update has a breaking changes in the Wasm toolchain that breaks #unoplatform's bootstrapper. Looks like the ordering of some msbuild targets has changed... Interestingly, the 9.0.200 preview does not have that change... It's probably just a matter of time.

I've been working on the past few days to work around a #dotnet #webassembly issue where AOT would be disabled for a method if it contains any catch or finally EH blocks, not necessarily for the same `try`. The runtime team has been very responsive with github.com/dotnet/runti..., thanks!

to use wasm64 in Emscripten, just compile and link with emcc -sMEMORY64 (wasm64 and memory64 are effectively synonyms)

Hey #dotnet folks if you’re using a CI/CD double check your resource URLs. A CDN has gone bankrupt and may cease operations in the next month. We are working to make transparent fixes but you can be proactive github.com/dotnet/core/...

I've been spending a few days shoveling myself in a hole on a #dotnet iOS+LLVM issue where the app was behaving very incorrectly, and it turns out that it's an issue where setting a Vector3 field also modifies the very next field, if it's also a Vector3... github.com/xamarin/xama... #unoplatform

Generating SBOM for NuGet packages #NuGet #dotnet #security https://www.meziantou.net/generating-sbom-for-nuget-packages.htm?utm_medium=social&utm_source=bluesky

Note for later: Building a #dotnet 9 Wasm app back-to-back without `dotnet clean` can cause trouble when using different AOT profiles. It seems that the SDK does not yet take into account significant differences in profile outputs, causing errors at runtime like that one: github.com/dotnet/runti...

The lowercase "ı" has struck again, it's clear that `ınternal` is not `internal`. A code generator in #unoplatform is doing some incorrect string manipulation which produces invalid C# code. Looks like we're missing some analyzers to catch a ToLower! #dotnet

absolutely incredible attack vector
