Gennady46 · Jun 6, 2024

I have Windows Forms Visual Studio Project; I have added the code to be able to use a finger instead of the mouse on touch screen monitor.When I use a mouse, everything is working, but when I use a finger to top and double top on the screen also working only if I do it on any item on the form,

Visual studio 2017, C# windows form wont display output of calculation.

I have created a Windows form ( grade calculator ) in visual studio 2017 using C#.

The build has no errors, but it will not display the result in the assigned label when I run it.

I know it is not a coding error because the form runs and displays on the machines of others, it just won't display the result on mine in visual studio 2017. so I am quite positive it is just a visual studio setting or something like that. but, I can't figure
out what setting it is I need to change or fix.

New Visual Studio, Visual Studio for Mac, .NET Core and Xamarin.Forms

Microsoft Build has always been a time when we deliver a wealth of developer-focused announcements. It’s an opportunity to share our vision for developer experiences across mobile, AR/VR, cloud, web, desktop, IoT and AI. This year, I’m excited to have brought this vision to life with more than a few exciting announcements:

.NET Core 2.1 RC

Future of Windows Desktop Development

Visual Studio 2017 version 15.7

Visual Studio for Mac version 7.5

Xamarin Forms 3.0 General Availability

Visual Studio Live Share Public Preview

Introducing Visual Studio IntelliCode

For an overview of announcements across the company, check out Scott Guthrie’s blog post; but for a round-up of Visual Studio and .NET headlines, read on.

.NET Core 2.1 RC

As of today, .NET Core 2.1 Release Candidate (RC) is available with a “Go-Live” license to use in production. .NET Core 2.1 improves on previous releases with hard-won performance gains and many new features:

ASP.NET Core SignalR. Developers have been using SignalR to build real-time web communication solutions since 2013 on the .NET Framework. The stack has been streamlined and improved to run on the cross-platform and higher performance .NET Core runtime. We also released SignalR as an Azure service.

ASP.NET Core web platform enhancements including support for Razor UI in class libraries, improvements in building WebAPIs, security enhancements, a new Identity UI library and HttpClientFactory.

Entity Framework Core 2.1 introduces significant capabilities like lazy loading, data seeding, new data providers and enhanced support for CosmosDB.

.NET Core 2.1 significantly improves build & runtime performance. It also introduces a new deployment and extensibility model for global tools.

ASP.NET Core 2.1 is more than 15% faster than version 2.0. This means that when ASP.NET Core is released, it will top the TechEmpower benchmarks as the fastest mainstream web framework on the planet.

Of course, .NET Core remains free, cross-platform, and open source – just as it has been since 2014.

Learn more about .NET Core 2.1 RC.

Future of Windows Desktop Development

While we’re excited to release .NET Core 2.1 RC, we’re not stopping there. Today, we introduced the roadmap for .NET Core 3, which brings desktop development to our open source .NET stack. We are adding Windows Presentation Foundation (WPF) and Windows Forms on top of .NET Core. As always, developers building Universal Windows Platform apps will also continue to benefit from all the .NET Core improvements.

.NET Core 3.0 will enable Windows desktop apps use a globally installed .NET, or an app local copy, or build a single .EXE which includes .NET. Thus, .NET apps will no longer be impacted by system-wide updates. More importantly, this will allow us to make improvements to WPF and Windows Forms that we previously could not have done with .NET Framework without risking compatibility to existing apps

With .NET Core 3.0, developers will have the ability to share and easily integrate UI controls across all the major Windows desktop frameworks. You’ll be able to incorporate whatever UI controls make the most sense for your scenario, or even take a phased migration approach to modernizing your app’s UI. Developers will be able to seamlessly integrate almost all the Windows 10 API surface area into their .NET apps such as Cortana, Windows Hello, Windows ML, Rome, and more. And developers will be able to take advantage of the performance improvements and new API’s in .NET Core.

Developers targeting .NET Framework 4.8, the next version of .NET Framework, will also benefit from the improvements we plan to make such as the new Edge-based WebView control that they can host inside their apps, with more controls planned. And support for XAML Islands bringing UWP UI into existing applications.

This roadmap represents a significant investment in Windows desktop development by empowering developers to adopt the latest innovations in Windows 10 and .NET Core in their WPF and Windows Forms apps.

Learn more about the .NET Core 3.0 Roadmap.

Visual Studio 2017, version 15.7

Our flagship IDE, Visual Studio, received a significant upgrade today with the announcement of Visual Studio 2017 version 15.7. John Montgomery’s blog post has a full run-down of all the new capabilities, but some of the more significant headlines include:

Cloud development: You’ll find several improvements to the project scaffolding and unit testing. Additionally, you can publish Helm charts directly to Azure Kubernetes Service (AKS). You can now also directly publish .NET applications to Kubernetes containers. For your ASP.NET and ASP.NET Core applications, you can configure the Key Vault connected service directly from the IDE.

Debugging: IntelliTrace’s new step-back debugging, first shipped in Visual Studio 2017 version 15.5, is now available for .NET Core applications. The feature automatically takes a snapshot of your application on each breakpoint and debugger step so you can step “back in time” to view previous application states.

MSVC C++ 17 conformance: Today, we are happy to announce we have reached full C++ 17 conformance in MSVC with Visual Studio 2017 version 15.7. We also added ClangFormat support for C++ developers in the IDE. Developers can use ClangFormat to automatically style and format your code as you type, in a way that can be enforced across your development team.

Python: This release contains an opt-in preview of the Python debugger based on the popular open source pydevd debug engine, offering improved performance for many debugging scenarios.

iOS and Android mobile development with Xamarin: The XAML editing experience has been greatly improved with full IntelliSense support. iOS devices can be provisioned for development with a single click, saving developers a lot of time and steps. Android and iOS project templates have been re-written to use the latest modern navigation patterns and are now better organized for improved discoverability.

Visual Studio for Mac, version 7.5

Visual Studio 2017 wasn’t the only IDE to get an update. Today, we’re announcing Visual Studio for Mac version 7.5. This release includes bug fixes, performance improvements, and several new features:

New editors for Razor, JavaScript, and TypeScript for building web projects

Updated UI and templates for building serverless solutions with Azure Functions and .NET Core

.NET Standard Library projects are now a fully supported option for sharing code between platforms when building Xamarin.Forms solutions.

Preview support for Team Foundation Version Control (TFVC) in Team Foundation Server (TFS) and Visual Studio Team Services (VSTS) has arrived addressing one of our top UserVoice requests. Developers now have the option to use the existing Git source control integration or the new TFVC integration to manage their code.

Learn more about Visual Studio for Mac, version 7.5

Xamarin.Forms 3.0 General Availability

Today, we’re announcing immediate availability of Xamarin.Forms 3.0. Xamarin.Forms 3.0 delivers improved stability, faster performance, and new capabilities aimed at making it easier for you to create beautiful apps that work on Android, iOS, macOS, and Windows devices.

Xamarin.Forms 3.0 now builds with .NET Standard 2.0 using multi-targeting, while still maintaining support for PCL profiles and other .NET Standard versions. Projects load much faster when you use .NET Standard project types.

Xamarin.Forms 3.0 also includes a strong focus on developer productivity. Many developers are already familiar with the Visual State Manager already found in XAML for UWP and WPF. It’s now available for Xamarin.Forms, too. We’ve also heard from many ASP.NET developers who can build amazing layouts for the web using Flexbox and CSS. To empower these developers to build equally impressive layouts on mobile, we’ve added two features to Xamarin.Forms: FlexLayout and CSS. Xamarin.Forms 3.0 introduces both features without compromising the existing XAML experience desktop developers have come to know and love. Finally, because Xamarin apps are deployed globally, we also included right-to-left language support and many quality improvements in the 3.0 release.

Visual Studio Live Share Public Preview

Today, we announced the public preview of Visual Studio Live Share. Now any developer can use Live Share to collaborate in real-time with other developers, with instant bi-directional collaboration directly from their existing tools like Visual Studio 2017 and Visual Studio Code. With Visual Studio Live Share:

It doesn’t matter if the developer sharing doesn’t use the same editor or have the same OS as you; join a Live Share session from your own development environment. No need to install project- specific dependencies or configure runtimes. You’ll view the project in your development tool, retaining all your customizations and themes.

Each team member in a Live Share session can separately open files, navigate, edit, and refactor code. Your changes are instantly reflected in your teammate’s editor. You can quickly jump to a teammate’s location and see their cursor as they make edits or pin to follow their actions. Want to focus their attention? Highlight a piece of code and it will highlight on their screen as well.

Use Live Share with any language on any application pattern, including serverless, cloud native, and IoT development. At Connect() 2017, we showed Live Share working with JavaScript and Node.js. Today, Live Share supports nearly every language supported by your development tool, including C#, Python, Java, Go, C++, and

Full-context sharing – Use Live Share to collaborate across all parts of your development workflow: co-editing, shared debugging, shared terminals, and shared servers (ports).

Visual Studio IntelliCode

Visual Studio IntelliCode is a new capability that enhances everyday software development with the power of AI. Today, IntelliCode provides intelligent suggestions to improve developer productivity and code quality in the tool that developers love, Visual Studio. Our vision is to apply AI to empower developers across the entire development lifecycle.

At Build, we shared a sneak peak of IntelliCode, showing how it uses AI to deliver better context-aware code completions, guide developers to code to the patterns and styles of their team, find difficult-to-catch code issues, and focus code reviews on areas that really matter.

Developers can sign up for news and a future private preview, as well as gain access to an experimental extension at http://aka.ms/intellicode
