#VISUAL BASIC 5.0 RUNTIME CODE#
We call the result the “super host.” Native code runtime and library components are linked into the super host. That's what we did, starting with Linux for the. The most obvious solution was to statically link the runtime into the launcher. It's responsible for being a native executable, discovering the runtime, and then loading the runtime and the managed app. It's sort of a new hosting model.Īs I said, we use a launcher for. In short, we needed to adapt the runtime to being embedded in a single file configuration.

There are two primary outcomes we needed to enable: include the runtime within the single file and load managed assemblies from within the single file. It's a publish option, right? In actuality, the work to enable single file apps was done almost exclusively in the runtime. You wouldn't necessarily think of single file apps as a runtime feature. Although it's common for language platforms to require launchers, other platforms like C++, Rust, and Go don't require them, and they offer single file as a default or an option you can use. Over time, we heard more and more feedback that people wanted a single file application solution. For example, Java and Node.js apps have launchers. We're not alone multiple other platforms have this too. That's how we ended up with multiple files: at least one for the launcher and another for the app. We needed to build a native launcher for discovering and loading the runtime for each supported operating system. NET Framework, even though we (very) briefly considered it. This led us to not replicate the approach we used for.
#VISUAL BASIC 5.0 RUNTIME UPDATE#
We also didn't want to require operating system updates to change the behavior (like needing to run Windows Update to get a. A driving goal was providing the same application behavior on all operating systems. NET Core, we had to start from scratch with many aspects of the platform, including how apps were launched. NET executable files (like myapp.exe), and then hands execution off to the. NET Framework is integrated into Windows. You could put a console or Windows Forms app on a network share and expect it run. NET Framework executables have been very small single files. NET Framework has been part of Windows and. Many people have correctly observed and noted that. Those will be covered in the following sections. There are some differences, depending on the operating system or application type.

Single file apps are supported for all application types (ASP.NET Core, Windows Forms, etc.). There's something truly simplifying and productive about launching a single file app from a network share or a USB drive, for example, and having it reliably just run on any computer without requiring installation pre-steps. This capability is appealing for command-line tools, client applications, and Web applications. They enable you to create standalone, true xcopy, single-file executables.
#VISUAL BASIC 5.0 RUNTIME FULL#
NET blog ( ) to learn about the full set of improvements in this release and why you should consider adopting. If you're mostly interested in performance improvements, please check out the. NET 5.0 that there simply isn't room to cover here, like P95 performance improvements, new diagnostic capabilities (like dotnet-monitor), and advances in native interop (like function pointers). NET 5.0 projects: single file apps, and ARM64. The features I want to tell you about are a direct outcome of those observations and predictions. We also look at where the industry is headed next and try to predict the new ways that developers will want to use. We listen to feedback from users, with most of it coming from GitHub issues. NET team chooses which new features and scenarios to enable. Many of the performance improvements and key changes we made to optimize scenarios (like Docker containers) have come from the runtime. This is even more true since Microsoft started the. NET platform and is therefore the source of many improvements and a key component of many new features and enabled scenarios.
