 17.5 Performance Enhancements

  • Build Acceleration for .NET SDK style projects: Significantly speeds up incremental builds for SDK-style .NET projects, reducing build times by up to 80%. 
  • External Sources De-compilation: Offers up to 10 times faster de-compilation of large modules, enhancing debugging efficiency. 
  • Razor & C# experience: Improves the overall development experience by addressing feedback and introducing support for code actions in Razor files. 
  • Quick Add Item: Introduces a faster way to add files and folders to solutions, streamlining the development process. 
  • Code Coverage: Makes substantial improvements to dynamic code coverage performance, resulting in over 35% faster tests. 

17.6 Performance Enhancements

  • Solution Open and Close: Dramatically enhances performance, particularly for larger projects like Chromium, reducing solution load and close times by up to 8 times. 
  • Git File History: Offers faster loading times for file and folder scenarios in Git repositories, with a remarkable 42% improvement in the Git public repository. 
  • Git Branch Switches: Reduces the time it takes to switch between Git branches by optimizing file system changes detection and processing. 
  • Lightbulb Improvements: Overhauls the diagnostics and code analysis architecture, delivering a significantly improved lightbulb/code actions experience. 
  • Performance Profiler stop collection: Implements parallel processing for NGEN PDB creation, resulting in 3.5 times faster stop collection.

17.7 Performance Enhancements 

  • F5 Speed enhancements: Boosts F5 speed for a quicker development cycle. 
  • Improved Light Bulb Performance in C#: Enhances the responsiveness and performance of the light bulb feature in C#. 
  • Memory consumption improvements in C# spell checker: Optimizes memory usage for the C# spell checker, improving overall performance. 
  • C++ Unreal Engine – IntelliSense optimization: Optimizes IntelliSense for C++ Unreal Engine projects, providing a more efficient development experience. 
  • Solution Explorer enhancements and Find in Files optimizations: Improves Solution Explorer and optimizes the Find in Files feature for faster and more effective searches. 

17.8 Performance Enhancements 

  • Improved Razor/Blazor Responsiveness: Enhances the responsiveness of Razor and Blazor projects, providing a smoother development experience. 
  • Enhanced F5 Speed: Further improves F5 speed for faster build and deploy cycles. 
  • Build Acceleration for Non-SDK style .NET Projects: Accelerates builds for non-SDK style .NET projects, reducing build times. 
  • Optimized IntelliSense for C++ Unreal Engine: Optimizes IntelliSense for C++ Unreal Engine projects, enhancing development efficiency.

    Is there a plan on migrate to the modern .net 8 or 9 ?

    Is there chance, that Visual Studio is NOT behind to Visual Studio Code????
    In Visual Studio Code is a lot better in CoPilot. It is able to “understand” the whole Project in terms of “workspace”, so it is able to give more meaningful suggestions.
    Visual Studio 2023 is nearly not useful. I change to use opeAI directly (assistent). Pay less, get more.
    Btw. 240 bucks per year is not really a small amount to get a not really useful tool.

    Please make a normal ramdrive for Windows 11 in addition to Dev Drive for intermediate compilation files (like OBJ’s and other). When workstation has 32Gb or 64Gb it is better (to not waste NVM/SSD resources) to store allmost temporal compilation files in memory.

    P.S. Many third party Virtual disks and RamDrives cause BSOD in Windows 11 (In Windows 10 all was ok)
