.Net Counter Support for New Instruments via Meters API

The .NET Counters tool now introduces integration of the .NET Meters API, encompassing new instrument options including "Counter" and "ObservableCounter"

The "Counter" keeps track of a value changing over time, with the caller reporting updates using "Counter.Add." In contrast, the "ObservableCounter" is like the Counter but the caller takes care of keeping track of the total value. Currently .NET Counters tool reports the rate of change in the total.

You can find these metrics in the list of the .NET counter metrics roster, offering enhanced visibility into system performance and resource utilization.Furthermore, we're actively planning to introduce additional instrument options in the future to enhance this capability even further.

New React TypeScript and ASP.NET Combined Templates

When we initially released the JavaScript/TypeScript with ASP.NET Combined Templates in this blog post, we got feedback that users deserve a better React TypeScript project creation experience. This new React TypeScript with ASP.NET combined template gets the tsconfig and SpaProxy set up out of the box.

  • Two new fields are added to Connect dialogue box Connect Dialogue Box
  • The Encrypt property now defaults to true (enabled) when connecting. If a server does not have a trusted certificate configured, the use of Trust Server Certificate set to true may be appropriate. For more details, please refer to the documentation

New IntelliTest now in Preview

IntelliTest explores your .NET code to generate test suites with high code coverage, powered by the latest version of the Z3 problem solver. When you Generate Tests, you have the ability to select which tests you’d like to preserve into a test project that can serve as your regression suite. As your code is updated, you can rerun IntelliTest to keep the generated tests in sync with your code.

Previous implementations of this Enterprise Edition feature only supported code targeting .NET Framework and did not support x64 configuration. This updated version includes the following:

Ennable this feature through Tools > Manage Preview Features and selecting IntelliTest support for NetFx and Net6 using Z3 v4 (requires restart).

Enable Intellitest

Then in your code, right click within a method and select IntelliTest (Preview) and either Create Project to create a project where your tests can be saved or Generate Tests to generate a set of tests to review and decide which ones to keep.

Performance Enhancements

Improved Razor/Blazor Responsiveness

Solutions using Razor and Blazor will experience better responsiveness. We achieved this by significantly reducing memory allocations during cross-process communications between Visual Studio and Roslyn. We tested the OrchardCore solution, and the results are impressive. To open the solution and get Razor intellisense ready, we allocate about 1.4GB less memory. Fewer heap allocations mean less work for the garbage collector, which results in improved responsiveness.

Enhanced F5 Speed

We’ve substantially enhanced F5 performance for native projects by optimizing how breakpoints get set up. The improvements seen by any given project depends on the number of files with breakpoints, the number of DLLs with symbols, etc. Additionally, we’ve optimized the PDB loading process for Windows applications, reducing the time required to load a PDB once it’s located. In our testing, these optimizations delivered a remarkable 20% speed improvement for Unreal Editor projects.

Enhanced F5 Speed

Optimized IntelliSense for C++ Unreal Engine

We’ve made improvements to the speed with which IntelliSense and colorization become available after opening a previously opened C++ file. We have always cached IntelliSense state for an opened file. In 17.8, we’ve restructured the reading from cache, such that the most critical information, including colorization and the highlighting of selected references, are computed first. This optimization helps you get productive sooner.

Build Acceleration for Non-SDK style .NET Projects

Visual Studio 17.8 extends Build Acceleration to managed applications targeting the non-SDK style projects (e.g. projects targeting .NET Framework 4.8 or lower) providing a substantial impact on build times. To enable, set an msbuild project property as follows:

<Project> 
    <PropertyGroup>  
        <AccelerateBuildsInVisualStudio>true</AccelerateBuildsInVisualStudio>
    </PropertyGroup>  
</Project>

This builds on the success introduced in 17.5 for SDK-style projects, reducing incremental build times significantly.

In our internal testing with in-house solutions, we noticed up to a 50% improvement in incremental build times. However, the actual improvement depends on the state of projects when the build begins. Specifically, the fewer the projects that have been modified in comparison to the total projects in the solution, the greater the improvement. The actual extent of improvement you experience will depend on the specific characteristics of your project and its modifications.

Enterprise Management

Administrators can now easily initialize client machines before delegating standard users control of updating or modifying their installation of Visual Studio. Now, you can programmatically install just the installer by executing "vs_enterprise.exe install --installerOnly".

Administrators that take advantage of our administrator update solution to deliver monthly security updates across their organization can now prompt users to close Visual Studio, which is a common situation that blocks administrator updates from applying. To enable the prompt, configure the new "AdministratorUpdatesNotifications" global policy, which is available in both Intune settings catalog and our ADMX Templates. Thank you to the administrator community who suggested this feature.

Feedback and suggestions

We would love to hear from you! You can Report a Problem or Suggest a Feature Feedback Icon by using the Send Feedback icon in the upper right-hand corner of either the installer or the Visual Studio IDE, or from Help > Send Feedback. You can track your issues by using Visual Studio Developer Community, where you add comments or find solutions. You can also get free installation help through our Live Chat support.
