FAQPage Schema
How do I measure .NET Aspire application startup performance?▼

To measure .NET Aspire application startup performance, this Skill collects dotnet-trace traces and computes the startup duration between DcpModelCreationStart and DcpModelCreationStop events from AspireEventSource.

Can I use dotnet-trace to assess the impact of code changes on Aspire startup times?▼

Yes, you can use dotnet-trace to assess code change impacts on Aspire startup times; this Skill analyzes the collected traces to calculate the exact duration of application initialization.

How do I customize trace collection for an Aspire TestShop project?▼

You can customize trace collection for an Aspire TestShop project by specifying custom project paths, setting iteration counts, and defining trace output directories before running the startup performance measurement.

What is the best way to track Aspire DcpModelCreation event duration?▼

The best way to track Aspire DcpModelCreation event duration is by analyzing dotnet-trace outputs to pinpoint the exact time elapsed between the DcpModelCreationStart and DcpModelCreationStop events.

Do I need dotnet-trace installed to measure Aspire startup performance?▼

Yes, you need the dotnet-trace tool installed, as it is a required dependency for collecting the diagnostic traces used to evaluate your Aspire application startup performance.
