In the February 2016 issue of MSDN Magazine, I showed how to create a custom scripting language based on the Split-And-Merge algorithm for parsing mathematical expressions in C# (msdn.com/magazine/mt632273). I called my language Customizable Scripting in C#, or CSCS. Recently, I published an E-book that provided more details about creating a custom language (bit.ly/2yijCod). Creating your own scripting language might not initially seem to be particularly useful, even though there are some interesting applications of it (for example, game cheating). I also found some applications in Unity programming.

Aurelia is one of the best frameworks that we have ever seen in terms of software design, hence, we decided to write a bunch of tools for its developers to pave the way for further usage.

aurelia-toolbelt is that, in which we tried to gather the best libraries in Javascript world together in aurelia fashion. Writing custom-elements, value-converters, and so on. We tried not to invent the wheel, so most of the work is a wrapper, or bridge( am not sure whether the way that we coded can be called bridge or not), around other libraries.

• Its is utterly important for us to provide a link as a reference to the libraries used, or inspired from, so that other developers can visit their product and decide on their own to use which, besides it's one way that we can respect the time and effort of those programmers.

• All libraries used in aurelia-toolbelt are open-source and free of charge; most of which are  MIT , however we will provide definition whenever it differs.

PM> Install-Package Hangfire

After installation, update your existing OWIN Startup file with the following lines of code. If you do not have this class in your project or don't know what is it, please read the Quick start guide to learn about how to install Hangfire.

public void Configuration(IAppBuilder app)
{
    GlobalConfiguration.Configuration.UseSqlServerStorage("<connection string or its name>");
    
    app.UseHangfireServer();
    app.UseHangfireDashboard();
}  

WebAssembly is moving beyond the browser and is pitched to become a foundational element of modern cloud-native architecture. It lets any language compile to universal binaries that run on any OS or processor, robustly sandboxed and with great performance. This session covers a new approach to running .NET in WASI environments. You’ll see how your existing .NET code could be built into WASI-compliant modules, plus the opportunities this opens. This is experimental, not yet a committed product. 

Rust has been ranked as one of the most loved languages by developers. In this series, you will learn the fundamentals of Rust development. We'll start by downloading the tools you need to program with Rust, walk through common concepts, and share what's unique about Rust. By the end of this series, you will have enough knowledge to go forth and write your own Rust programs. It's highly recommended that you watch this series if you have prior experience with programming in another language. 

System.InvalidOperationExceptionWhen called from 'VisitMemberInit', rewriting a node of type 'System.Linq.Expressions.NewExpression' must return a non-null value of the same type. Alternatively, override 'VisitMemberInit' and change it to not visit children of this type. 

protected override Expression VisitMemberInit(MemberInitExpression node)
 {
       if (node.NewExpression.NodeType == ExpressionType.New) 
            return node;
        return base.VisitMemberInit(node);
 }

Hello! I work for the Angular core team on internationalization (i18n) and we are trying to get a better idea of the things that we need to improve/focus on in Angular regarding i18n. I created this survey: https://goo.gl/forms/0BIXXVP58RqbzzBM2 If you care about internationalization, please take 5mn to do it! Thanks!

 LINQ to Entities does not recognize the method 'System.String ToString()' method, and this method cannot be translated into a store expression.

 public Task<EditUserViewModel> GetUserByRoles(int id)
        {
            return _users.AsNoTracking()
                    .Include(a => a.Roles)
                    .Project(_mappingEngine)
                    .To<EditUserViewModel>()
                    .FirstOrDefaultAsync(a => a.Id == id);
           
               
        }

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).
