.NET Foundation Project Updates

Project Spotlight

Each month Project Spotlight shines a light on an interesting open source project and its maintainers.

In June, .NET Foundation Marketing Committee member, Isaac Levin, spoke with Maintainer of the Wix Toolset project, Rob Mensching, to talk about how .NET Developers who build desktop applications for Windows can take advantage of advanced publishing options with the Toolset.

Watch the interview: Wix

The WiX Toolset is the most powerful set of tools available to create your Windows installation experience. The tools integrate seamlessly into your standard development (CI/CD) practices with text based source code, command-line tools and MSBuild/Visual Studio integration to create installation packages for your Windows software. The WiX Toolset was Microsoft's first Open Source project released in 2004 and is now a member of the .NET Foundation and supported commercially by FireGiant.

New Projects

The .NET Foundation would like to welcome the following new projects!

bUnit NFLogo bUnit is a testing library for Blazor Components. Its goal is to make it easy to write comprehensive, stable unit tests. bUnit builds on top of existing unit testing frameworks such as xUnit, NUnit, and MSTest, which run the Blazor component tests in just the same way as any normal unit test. bUnit runs a test in milliseconds, compared to browser-based UI tests which usually take seconds to run.
FIDO2 NFLogo FIDO2 enables passwordless sign in for all .net apps (asp, core, native) and provides a developer friendly and well tested .NET FIDO2 Server / WebAuthn relying party library for the easy validation of registration (attestation) and authentication (assertion) of FIDO2 / WebAuthn credentials, in order to increase the adoption of the technology, ultimately defeating phishing attacks.
HIBP dotnext ';--have i been pwned? (HIBP) is a a free online resource for anyone to quickly assess if they may have been put at risk due to an online account of theirs having been compromised or "pwned" in a data breach.
.NEXT dotnext .NEXT (dotNext) is the family of powerful libaries aimed to improve development productivity and extend .NET API with unique features which potentially will be implemented in the next versions of C# compiler or .NET Runtime.
Reaqtor Reaqtor Reaqtor is a framework for reliable, stateful, distributed, scalable, high performance event processing based on Reactive Extensions (Rx).

New Releases

NuGet Package Explorer is now a Web App too!

By Popular demand, NuGet Package Explorer is now a Web App. The new solution is a WinUI, Windows Community Toolkit and Uno Platform powered solution which runs on the Web, via Uno's support for WebAssembly and .NET 6 for WebAssembly.

DotVVM 3.0 Released

If you haven't heard about DotVVM yet - it's an MVVM framework which you can use to [build ASP.NET Core web apps with just C# and HTML](DotVVM or to modernize legacy ASP.NET apps to .NET 5. DotVVM is based on Knockout JS, its download size is just about 60kB, and comes with a set of built-in UI controls.

DotVVM 3.0 contains many improvements, and introduces several new features:

  • Easier interaction with the page viewmodel from JS or TS code - you can import JS module in the page and call its functions from DotVVM data-bindings, and also call DotVVM commands from your JS code. It makes it easy to integrate any third-party JS library or component.
  • Support for lambdas and variables in data-binding expressions - it's now easier to make client-side searching, ordering, or transform data returned from the server or REST API before it's passed in the viewmodel.

More info


NUnit Analyzers 3.1 and 2.1 are available. The 3.1 version continues to enhance the experience of using NUnit with the C# 8 Nullable Reference Types feature. (The 3.x versions have additional features that only work in Visual Studio 2019 and newer. The 2.x versions are available for those using Visual Studio 2017.)

NUnit Adapter 4.0.0-beta.2 resolves some issues and improves performance. A major change in this version is the upgrade of the NUnit.Engine to version 3.12, and thus Mono.Cecil is no longer used. Instead it has a reduced version (based on Mono.Cecil) packed into TestCentric.engine.metadata doing the same job with navigation data.

Oqtane 2.1 Now Supports Multiple Databases

On June 4, Oqtane announced the official release of Oqtane 2.1, a new major release of the popular modular application framework for Blazor, adding native support for SQL Server, SQLite, MySQL, and PostgreSQL to its growing list of framework capabilities.

A total of 94 pull requests containing 261 commits by 6 different contributors were integrated into this release.

The 2.1 release is available for download on Github and we encourage the community to visit the repo often to keep abreast of the latest developments.

.NET Foundation Committee Updates

Announcing the .NET Foundation Education Committee

We're excited to announce we've officially launched the Education Committee. Brian Jablonsky has stepped up to chair the committee. The education committee will be responsible for developing, sponsoring, and providing educational opportunities for the .NET community and is open to anyone who wants to participate. They meet every 2nd and 4th Wednesdays of the month from 11:00 AM to 12:00 PM ET.

Their first initiative is building and launching the .NET Foundation Academy, a program for higher education computer science students to learn about software development using .NET. The first curriculum focuses on full stack web development using C# and .NET 6. Students will work in teams on projects they propose, design, and implement. The course is a 12 week program consisting of a 2.5 hour class with a mix of lecture and workshops each week.

If you are interested in joining the education committee, please read more about joining on the education committee's GitHub repository.

Outreach Committee Announces Proposal Process

The .NET Foundation's Outreach Committee is happy to announce that we've finalized our proposal process. If you have an idea or project that you think can help promote the adoption of .NET, C#, F#, or other related technologies, you can now propose projects directly to the .NET Foundation.

Read more about the details on our blog.

Board Nominating Committee Formed

The Nominating committee for the 2021 board elections had its organizational meeting. The nominating committee will be recruiting potential candidates for this year's board elections. In the next month, you'll hear more about potential candidates so you can make an informed choice when the election is held later this summer.
