New Process For Newsletter Submission

We have a new process for submitting project news! Yay! No more cumbersome spreadsheets! Check out the README for more details. We also have a handy YouTube video that walks through the process.


Project Onboarding Process Improvements

Project onboarding is now handled publicly via GitHub issues. The process is now more transparent and visible. Progress through the process is easily visualized via a GitHub project board.

This is part of our effort to move to open processes so action groups and community members can more easily participate. The previous process was buried in emails and word documents and lacked visibility and transpancey.

We have an issue template for new project applications here: https://github.com/dotnet-foundation/projects/issues/new/choose

Key goals:

Clear status to projects
Use milestones and labels to batch up applications into monthly review cycles
Enable action group members to review and help out on applications
Comments / pull requests / etc. are welcome.

Join an Action Group!

We recently announced our new Action Groups: a way for .NET Foundation members to join teams and get directly involved in helping the .NET Foundation scale to the next level. Our teams include the following:

Corporate Relations
Project Support
Speakers and Meetups
Technical Review

We’ve been figuring out logistics and communications as we move to working publicly and with a large team. We’ve settled on GitHub Organizational Teams and are continuing to roll this out to the teams – we’ve mostly started with Marketing and Project Support so far, but are now working on getting other groups more involved in our day to day business.

.NET Foundation Project Updates

ML.NET 1.2 released

ML.NET 1.2 and updates to Model Builder and the CLI were released on early July 2019. ML.NET is an open-source and cross-platform machine learning framework for .NET developers. ML.NET also includes Model Builder (a simple UI tool for Visual Studio) and the ML.NET CLI (Command-line interface) to make it super easy to build custom Machine Learning (ML) models using Automated Machine Learning (AutoML). Using ML.NET, developers can leverage their existing tools and skill-sets to develop and infuse custom ML into their applications by creating custom machine learning models for common scenarios like Sentiment Analysis, Price Prediction, Image Classification and more!

The following are some of the key highlights in this release:

General availability of TimeSeries support for forecasting and anomaly detection
General availability of ML.NET packages to use TensorFlow and ONNX models
Easily integrate ML.NET models in web or serverless apps with Microsoft.Extensions.ML integration package
MLNET CLI and Model Builder for Visual Studio were updated with multiple improvements

For further details on the ML.NET 1.2 release, check this Blog Post:

Cake v0.34.0 released & v0.34.1 released

Version 0.34.0 has several features, improvements and bug fixes, full details in the linked blog post but a few highlights in this release:

Improved MSBuild 16 (VS2019) tool resolution
Update to Roslyn version 3.0.0
Updated to NuGet client version 5
NuGet pack support for several new nuspec elements

Version 0.34.1 is just a minor release as a hotfix to address an issue breaking scripts when the dynamic C# keyword was used in build scripts. This was a side effect of updating from Roslyn 2.x to 3.x.

🎉 We’re also happy to share that Cake turned five years old this May! And we’ve just done our 100th Cake release! 🎉
Huge thanks to our contributors and users! Wouldn’t have been possible without your support! ❤

Migrate ASP.NET Web Forms Sites to .NET Core using DotVVM

Did you know that DotVVM can be used to incrementally modernize old ASP.NET Web Forms applications and lift them to .NET Core? It is much easier than doing a full rewrite, and the application can be deployed at any time during the entire process.

Install DotVVM NuGet package in your Web Forms site
Create a DotVVM master page using the same CSS
Start converting ASPX pages to DotHTML syntax, one at a time
When all the Web Forms pages are gone, change your CSPROJ to use .NET Core

We have created some useful resources that will help you in this process.

New Fluent API for the IContainerRegistry
Added several new API’s to IContainerRegistry and IContainerProvider that significantly reduce the need to depend directly on the root container

New initialization API’s including IInitialize, IInitializeAsync & IAutoInitialize. These all help you to replace the now Obsolete OnNavigatingTo from INavigatingAware and INavigationAware
Automatic ViewRegistrion
Additional XAML Extensions… all XAML Extensions are now fully bindable
Enhanced Modal logic that should eliminate the need to ever specify whether to use Modal navigation when Navigating back from a page.

Akka.NET v1.3.14 Released

Maintenance Release for Akka.NET 1.3 You know what? We’re going to stop promising that this is the last 1.3.x release, because even though we’ve said that twice… We now have another 1.3.x release.

1.3.14 consists of non-breaking bugfixes and additions that have been contributed against the Akka.NET v1.4.0 milestone thus far. These include:

Akka.Cluster.Sharding: default “persistent” mode has been stabilized and errors that users have ran into during ShardCoordinator recovery, such as Exception in PersistentShardCoordinator ReceiveRecover;

Akka.Remote: no longer disassociates when serialization errors are thrown in the remoting pipeline – the connection will now stay open;

Akka.Cluster.Tools: mission-critical ClusterClient and ClusterClientReceptionist fixes;

SourceLink debugging support for Akka.NET; and

Akka.Persistence: Allow AtLeastOnceDelivery parameters to be set from deriving classes;

Akka.Persistence.Sql: BatchingSqlJournal now preserves Sender in PersistCallback; and

Akka: bugfix – coordinated shutdown timesout when exit-clr = on.
