When you’re dealing with complex and structured data, you need to determine whether the data is valid or not. JSON-Schema is the standard of JSON documents that describes the structure and the requirements of your JSON data. In this two-part series, you’ll learn how to use JSON-Schema to validate data. 

Today, we are releasing an update to .NET 8.0.400 SDK due to an issue with (MSBuild Crash when publishing containers)[dotnet/sdk#42731].

The .NET 8.0.401 release is available for download. This SDK includes the previously released .NET 8.0.8 Runtime and is in support of Visual Studio 17.11 release. The latest 8.0 release is always listed at .NET 8.0 Releases.

ASP.NET 5 beta7 is now available both on NuGet and as a tooling update to Visual Studio 2015! This release also includes the first public preview of the .NET Execution Environment (DNX) for Mac and Linux based on .NET Core – no Mono required.

Git + .NET/Mono = ❤  http://libgit2.github.com

LibGit2Sharp brings all the might and speed of libgit2, a native Git implementation, to the managed world of .NET and Mono. 

$ git init /d/temp/rooted/path

string rootedPath = Repository.Init(@"D:\temp\rooted\path");
Console.WriteLine(rootedPath);

$ git add --all .

using (var repo = new Repository("path/to/your/repo"))
{
    Commands.Stage(repo, "*");
}

$ git checkout <branch>

using (var repo = new Repository("path/to/your/repo"))
{
    var branch = repo .Branches[branchName];
    Branch currentBranch = Commands.Checkout(repo , branch);
}

Learn how to build enterprise applications using ASP.NET Core 3 and following the principles of Clean Architecture. This talk provides practical guidance and will cover architecture, technologies, tools, and frameworks. 

As with every .NET release, Microsoft improves the performance of the runtime and guess what: This release is no exception to this. In this blog post, I want to go through some of the improvements made so far (.NET 8 preview 3).
