  • .NET Core 3 – what impressed me

    This are the things that have impressed me: Async Streams ( think in conjunction with about EFCore / SignalR / gRPC / Observables)  .NET Default Interface members ( not appliable to classes  – so multiple inheritance is a problem just for interfaces…) Deconstruct – see a class from his properties Switch  – they improved Switch…

  • String interpolation for EFCore and Like

    I have had a problem with EF Core and String Interpolation – until I realized that was a problem with sp_executesql But let’s see the whole problem. ta EFCore supports string interpolation –  that means,if you give this code <context>.<table>.FromSql($”select blabla from table where id={id}”) it will transform into exec sp_executesql N’select blabla from table…

  • Dotnet Try

    I have wrote a blog post about DotNet CLI Tools I did not mention one that is super important: DotNet Try : https://github.com/dotnet/try You can see at https://github.com/dotnet/try how to install it . Or,to use in Docker,check my files to install in Docker https://github.com/ignatandrei/Presentations/tree/master/2019/shorts/NetCoreGlobalTools/dotnetTry   . To edit files in Docker,use Visual Studio Code with Docker and Remote Development and Docker extension.…

  • [PostEvent] Talks by Softbinator

    The organizers from Talk from Softbinator were kind enough to select me for a presentation. Again,my presentation about .NET Core and Angular Everywhere. Source Code at https://github.com/ignatandrei/angNetCoreDemo/  The presentation was supposed to take 1/2 hour – and it took 1 hour with all the explanations.

  • Correct abstraction–.NET Core IFileProvider

    Create the right abstraction and they will implement it. I was delighted by finding that the .NET Core has an IFileProvider : https://docs.microsoft.com/en-us/dotnet/api/microsoft.extensions.fileproviders.ifileprovider?view=aspnetcore-2.2  . An obvious implementation is PhysicalFileProvider : https://docs.microsoft.com/en-us/dotnet/api/microsoft.extensions.fileproviders.physicalfileprovider?view=aspnetcore-2.2 A not so obvious implementation,but normal from a programmers mind,is NullFileProvider: https://docs.microsoft.com/en-us/dotnet/api/microsoft.extensions.fileproviders.nullfileprovider?view=aspnetcore-2.2 And,because we have already 2 providers,makes sense a CompositeFileProvider: https://docs.microsoft.com/en-us/dotnet/api/microsoft.extensions.fileproviders.compositefileprovider?view=aspnetcore-2.2 And because…

  • Simple serialize of encoding

    My problem was the serialize of the Encoding . Let’s suppose that we have a class that have a property Encoding( maybe to read a file ). We want to serialize this class in order to let the administrator/people to decide what will be the encoding. When we serialize( obvious,with NewtonSoftJson),we obtain this kind of…
