A .NET GIS solution that is fast and reliable for the .NET platform.
NetTopologySuite is a direct-port of all the functionalities offered by JTS Topology Suite: NTS expose JTS in a '.NET way', as example using Properties, Indexers etc...

"Going forward, we do not plan to evolve Visual Basic as a language," the .NET team said. "This supports language stability and maintains compatibility between the .NET Core and .NET Framework versions of Visual Basic. Future features of .NET Core that require language changes may not be supported in Visual Basic. Due to differences in the platform, there will be some differences between Visual Basic on .NET Framework and .NET Core."  

In .NET 6 (preview 4), two long-awaited types have been introduced as part of the core library. DateOnly and TimeOnly allow developers to represent either the date or time portion of a DateTime. These two new types are structs (value types) and may be used when your code deals with date or time concepts independently. Both types can be found in the System namespace. Using these new types may align well with how databases allow similar data to be represented. Specifically, these types align well with the SQL Server date and time data types. 

Technical Debt is a metaphor for shortcuts and hacks in software that make it more difficult to change and maintain than it could be with an optimal design. Many applications have accumulated a large amount of technical debt, and figuring out how to deal with it is a fairly common challenge for many developers 

This is also our first release from the brand new .NET Community Toolkit repository, which will be the home of all our .NET libraries going forward. 

Ionic has been around for two years now. It is a great set of tools for developing hybrid applications based on AngularJS. Ionic is extremely popular at the moment, with more than one million applications built and a growing community of thousands of developers. 

In a Visual Studio Live! conference keynote Tuesday a couple of Microsoft program managers were on hand to discuss what's going on with .NET today and tomorrow, clearly signaling that .NET Core is the future of the ecosystem and that programmers should use it for all new development projects.

In order to avoid bifurcating the linting tool space for TypeScript, we therefore plan to deprecate TSLint and focus our efforts instead on improving ESLint’s TypeScript support.
