Create a project with .NET Framework 6 using any of the templates or tools mentioned above.
Run the project with dotnet watch run to enable hot reload.
Make changes to your code in your code editor and save the file. You should see a message in the terminal window saying "Hot reload of changes succeeded".
Switch to your browser or application window and see the changes applied without restarting the application.
.NET Framework 6 also introduces profile-guided optimization (PGO), which is a technique that optimizes the native code generated by the JIT compiler based on the actual behavior of the application. This improves the startup time, throughput, and memory usage of the application. To use PGO with .NET Framework 6, follow these steps:
Create a project with .NET Framework 6 using any of the templates or tools mentioned above.
Build the project with dotnet publish -c Release -r [rid] to generate a self-contained executable for your target runtime identifier (rid). For example, you can use dotnet publish -c Release -r win-x64 for Windows x64.
Run the executable with [project-name].exe --collect to collect profiling data for your application. For example, you can use HelloWorld.exe --collect for a console application named HelloWorld.
Run the executable again without the --collect option to use the optimized code generated by PGO. You should see a faster startup time and better performance.
.NET Framework 6 also includes other features that improve performance, such as tiered compilation, ready-to-run images, trimming, single-file applications, and more. You can learn more about these features and how to use them on the official .
