Out now: The Microsoft Fluent UI #Blazor library v5! It is finally here. As we've been saying (for ~2 years), this is not just a drop-in replacement for v4. But we have a lot of docs and an MCP server to help you migrate. See www.fluentui-blazor.net for more information. Packages are on NuGet Now!

Oeh, I like that! We'll have an MCP server for Fluent UI v5 as well. I might just 'borrow' this idea 😉

Vincent Baaij @baaijte.net · 08/04/2026

Packages are available on NuGet now. Use Microsoft.FluentUI.AspNetCore.Components --prerelease Demo and docs site: fluentui-blazor-v5.azurewebsites.net The v5 ToDo list: github.com/microsoft/fl... Currently working on for RC3: DataGrid reorderable columns (also showing pinned columns)(2/2)

We're working on getting some quirks out of the way with publishing the MCP server package, but the rest is available on NuGet now. Remember, you need to use the `--prerelease` switch to find the RC packages.

Vincent Baaij @baaijte.net · 17/02/2026

Out now: The Microsoft Fluent UI #Blazor library v5 RC1! This is the next major version. Lots of breaking changes but also lots of enhancements, beter APIs, better docs and an MCP server to help you use the library to it's fullest!

Vincent Baaij @baaijte.net · 13/02/2026

Out now: The Microsoft Fluent UI #Blazor library v4.14.0! Yes, that's a new v4 version in spite of all the v5 work we're doing. Highly demanded addition is support for hierarchical data in the DataGrid! See www.fluentui-blazor.net/WhatsNew for the overview. Packages are on NuGet now.

Hopefully somewhere in the next 2 weeks.

Coming soon to the Fluent UI #Blazor library... Hierarchical data. Finally, nesting rows will be possible! Oh, and I am now allowed to tag this with #MVPBuzz 😁

Well, I'm not an admin there (otherwise we'd own that too) but I happen to know who is 😉. I'll bring you into contact. Don't think it is much extra work (besides renaming namespaces)

Love this! To prevent fragmentation and end up with Fluent UI Blazor components everywhere, maybe you are willing to consider to add this to the community package? See github.com/fluentui-bla.... Fully endorsed by us (the maintainers of the library)

Items is the parameter with which you can provide the rowdata that you want to render in the grid. The DataGrid is generic so Items is an IQueryable set of 'T' items

000

Vincent Baaij @baaijte.net · 23/07/2025

Data is a property (of type Object) we added to every Fluent component which you can use at will to 'transport' any data you want/need

100

Vincent Baaij @baaijte.net · 23/07/2025

@ref allows you to create a link between the rendered component and an instantiation of the corresponding class (standard Blazor thing)

000

Vincent Baaij @baaijte.net · 23/07/2025

Well, not to push things of our plate, but this is indeed not a FUIB issue. Hot Reload is messing things up there.

Hi, Fluent UI Blazor library maintainer here. How can we help?

Vincent Baaij @baaijte.net · 17/07/2025

I was made aware that this is actually our 100th release. Quite a milestone! #blazor

Out now: The Microsoft Fluent UI #Blazor library v4.12.1! Details at fluentui-blazor.net/WhatsNew. As the summer break period is here and we are focusing our attention on building the v5 version, updates to v4 will be less frequent moving forward. Stay tuned for more info!

You can now choose from 3 different Tab sizes

Vincent Baaij @baaijte.net · 16/07/2025

Yup, we are moving some stuff around and that lead to breaking that part. Everything should be up and running again, though.

110

Vincent Baaij @baaijte.net · 14/06/2025

I'm guessing the first.. But in general, what's the ratio for the two groups?

000

Vincent Baaij @baaijte.net · 08/06/2025

PSA: Due to an issue with the .NET SDKs ( github.com/dotnet/aspnetc…) we have temporarily switched back to using 9.0.204 and removed targeting net10.0. We will be back on latest versions as soon as the next SDK patches become available (which I think is next week)

Vincent Baaij @baaijte.net · 06/06/2025

Out now: The Microsoft Fluent UI #Blazor library v4.12.0! 27 PRs merged and 3(!) new contributors. See the image for what this version will bring to a future #Aspire Dashboard release. All the details at fluentui-blazor.net/WhatsNew. An in-depth blog will come next week.

Vincent Baaij @baaijte.net · 21/05/2025

We think this is significant enough to warrant a minor version jump. Therefore the next version we release will be v4.12.0. As you may know, this library powers the Dashboard in .NET #Aspire. So, if all goes according to plan, this will be available in the next release of that as well.

Vincent Baaij @baaijte.net · 21/05/2025

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!

Vincent Baaij @baaijte.net · 08/05/2025

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.
