How to pass Fast Startup test with a .NET startup app?

Hi @Hank , Welcome to Microsoft Q&A,

Your app may be flagged for poor startup performance, long initialization time, or slow resource loading.

Here are several ways to optimize:

1. Reduce the workload at startup

• Lazy loading: Try to avoid loading too many resources or initializing unnecessary components when the application starts.
• Asynchronous initialization: If some initialization processes (such as database connections, network requests, etc.) can be completed asynchronously, consider using asynchronous methods (such as async/await) to avoid blocking the UI thread.

2. Reduce I/O operations during startup time

• Minimize file I/O operations when the application starts. You can speed up the startup by caching file data or delaying file operations.

3. Reduce the startup dependencies of the application

• Minimize the external resources that the application depends on when it starts, such as network services, remote databases, or third-party services. These operations may affect the startup performance of the application due to network delays or service response times.

4. Minimize the UI burden

• Make sure that only necessary UI elements are drawn when the application starts, and avoid initializing too many controls. For more complex interfaces, you can load interface components in steps or use virtualization technology.

If it is still marked as a problem after optimization, you can use the detailed report generated by the assessment tool to find the specific performance bottleneck and further optimize it.
