Screenshot of a hex editor with a PE file open, on the left there's a tree with the headers, sections and other parts of the file format. On the right there's a typical table of bytes in hex.

Finally had time over the holidays to realize a long-standing dream of mine: a hex editor that knows about the PE file and .NET metadata format. You can click any byte and it will show you which data structure it is in the tree. Every byte is covered.

The parser is at github.com/KirillOsenko...

Blazor Community Standup - Integrate .NET in JavaScript apps YouTube video by dotnet

I was talking about it in the beginning of www.youtube.com/live/tAh899G...

In the video I'm using `wasmbrowser` template that is shipped in `wasm-experimetal` workload. It's plain C# with JS interop in the browser

DataGrid resize enhancement

For the upcoming release of the Microsoft Fluent UI #Blazor library, we greatly improved the UI for resizing a DataGrid when using your mouse. Now you can start a resize action on any row (instead of just on the header). A resize indicator bar will be shown across the whole colum!

A code editor interface with a language selection dropdown highlighting C# and a pop-up labeled "New!" on the right.

Take screen width and height into account when positioning menu

Out now: The Microsoft Fluent UI #Blazor library v4.11.9! Porting changes made in Aspire over to the components (see image). Lots of other fixes and, of course, new icons. See fluentui-blazor.net/WhatsNew for the details. Packages are available on NuGet now.

If you pause the app in VS, where does it stop?

Some more "Doom clone" testing in Blazor WASM.

1. Discovered I can make a Winforms app to run Blazor apps without a local server.
2. Added some basic textures with transparent rectangles overlay to create depth. Still can't figure out complex textures 🙄

Thank you for sharing once again! I have already seen some of these, some are new to me. If you see any new ones, I would be happy if you bump them here.

Thank you for sharing. I didn't seen this one yet, taking a note. If you have more, I would be glad if you post them as well.

I'm collecting common failures.

Do you have specific scenarios that happen to you? Are they reproducible or happen randomly?

Why was it so complicated in Blazor? Was it .NET in general or something blazor specific? How did you do the integration?

I agree. The entire .NET ecosystem is actually on the avant-garde of WebAssembly.

In addition to the Blazor work, the .NET team has done some awesome stuff. Here, for example, is how we used Aspire.
