.NET Core Community Home

.NET Core Community (referred to as NCC) is an unofficial, non-profit open source community based on the .NET technology stack. It was established in mid-2016 by a group of young people in conjunction with nearly 100 .NET developers. We hope that through our efforts, we can make the .NET ecosystem more exciting.

The History of NCC

NCC was founded in mid-2016, the original name is ".NET Core China Studying Group". At the same time, we created a QQ Group called "dotNET Core Studying Group".

The original goal of NCC was to translate the documentation of Microsoft ASP.NET Core. We have received a lot of help and encouragement from many people (List of contributors for 2016 translation project). And the works of our translation also provided great convenient for the first Chinese developers who learned ASP.NET Core.

After two years of challenge, after several name adjustments, NCC became an open source community organization with more than one dozen projects and multiple sub-teams.

We have received support from many people, including the sponsorship of JetBrains.

At the beginning of 2019, we tried to cooperate with various local .NET technology communities in China and jointly launched the .NET China Community Joint Meeting (NCJM), and provided the community with the NCC domain name asset 'dotnet-china.com'. We enabled the new domain name 'dotnetcore.xyz' instead.

At the end of 2019, we adopted and launched MEMBER CODE OF CONDUCT. The four new rules and regulations revised and drafted by the community Revision and Drafting Working Group (2019) passed the NCC PMC vote, and in Effective from January 1, 2020.

In 2020, a special year, we have updated the community rules and withstood multiple huge challenges. Member projects have made great progress. Surging has completed the incubation of NCC for a broader prospect and established an independent community. FlubuCore became the first .NET Foundation member project in our community. NCC Alipay SDK completed its historical mission and was archived.

Since 2020, our community has been under attack and defamed by certain extremist technologists and a few self-serving authors of open-source projects. However, NCC has received support from the majority of the technical community and a vast number of developers who have the wisdom and talent to discern the truth. They are the backbone of .NET.

In the years 2023-2024, we will make a magnificent transformation and continue to explore a new future.

We will bring more surprises and achievements to everyone in 2024.

Members' Code of Conduct

In order to build an open, innovative, inclusive and welcoming community, we have published the Code of Conduct for Members.

(It has been updated.)

Repos and Projects
