This is a list of notable software packages which were published under a proprietary software license but later released as free software or open source software, or into the public domain. 

To be clear: this is not Silverlight. This is, in fact, a re-implementation of Silverlight that uses Web Assembly instead of browser plugins to achieve its goals.

This is the final release candidate (RC) for .NET 7 and is supported in production. 

Blazor WebAssembly is still in preview and is not part of the .NET Core 3.0 release. 

In case you are curious, a new benchmark appeared. The benchmark is really simple at present, but I think their plans are to increase the complexity over time to show a more real-world use case than something like the TechEmpower benchmarks which are typically optimized for performance.

Angular CLI 1.1 is out and here are some notable new features:

• outputs smaller and faster bundles by default,
• now comes with a new welcome screen when creating a new application,
