There has never been a better time to be a .NET developer, you can now build Android, iOS, Linux, Mac, and Windows applications with .NET all in Open Source. In this session we will run through some of the new innovations including the .NET Framework updates, .NET Standard, Universal Windows Platform updates, .NET Core, managed languages and more. We will also review the updates to Visual Studio and Visual Studio Code to make you a better developer, come see some of the latest productivity features in these tools including managing code style, searching your source and more.
 

As of April 1, 2020 Log4Net is a dormant project of Apache Logging Services. The dormant status means the project has been classified as inactive since it has had no recent development activity and there are no active volunteers to perform code reviews, commit code, or perform releases. Although it is possible volunteers might choose to participate in the future, it is best to assume there will be not future development or releases.

In this article we are going to discuss how to insert, update and delete data into database using ASP.NET MVC 4.0. There is a Layout page and Data base script that we are going to use for this but we are not going to discuss much  how to create a Layout page and database script here in detail. 

• WPF improvements for spell check, support for per-user custom dictionaries and improved touch performance 
• Enhanced support for Elliptic Curve Digital Signature Algorithm (ECDSA) X509 certificates
• Added support in SQL Connectivity for AlwaysOn and Always Encrypted
• Profiling improvements related to IcorProfilerInfo interface and introduction of Ngen PDBs
• System.Transactions APIs now support distributed transactions with a non-MSDTC coordinator
• Many other performance, stability, and reliability related fixes in RyuJIT, GC, WPF and WCF.

C# can be developed and run on more and more platforms, and thanks to the "Roslyn" language engine you can increasingly make your own tooling for it. C# 7 embraces several new features for working better with data, such as tuples and pattern matching. Come see how you can start using C# 7 today! 

Like many other modern JSON databases, RethinkDB is schemaless: the developer doesn’t have to define a fixed structure or specify field types when creating a new table. In cases where validation is desirable, it’s up to the developer to build it into their application. 

MockHttp is a testing layer for Microsoft's HttpClient library. It allows stubbed responses to be configured for matched HTTP requests and can be used to test your application's service layer. 

var mockHttp = new MockHttpMessageHandler();

// Setup a respond for the user api (including a wildcard in the URL)
mockHttp.When("http://localhost/api/user/*")
        .Respond("application/json", "{'name' : 'Test McGee'}"); // Respond with JSON

// Inject the handler or client into your application code
var client = mockHttp.ToHttpClient();

var response = await client.GetAsync("http://localhost/api/user/1234");
// or without async: var response = client.GetAsync("http://localhost/api/user/1234").Result;

var json = await response.Content.ReadAsStringAsync();

// No network connection required
Console.Write(json); // {'name' : 'Test McGee'}

we will look at some of the approaches that you can take to make optimized and better performing ASP.NET web sites. Some of these principles can also be applied to websites created in a technology other than ASP.NET.

Caching is a powerful tool in a programmer's toolbox but it isn't magic. It can help scale an application to a vast number of users or it can be the thing dragging down your application. Layered caching is a technique of stacking different types of cache on top of each other which play to different strengths.
