3.1.2

Version 3.1.2

• Fix HttpException: Request is not available in this context in the WEB package when calling TrackDependency from Application_Start in classic ASP.NET. The WEB activity processors now safely handle the case where HttpContext.Request is not yet available.
• Fix #3163: TelemetryConfiguration.CreateDefault() on classic ASP.NET now returns a configuration already populated from ApplicationInsights.config (connection string, sampling, storage, live metrics, request/dependency tracking, etc.). A new PreApplicationStartMethod (WebApplicationInsightsInitializer) materializes and populates the singleton before Application_Start runs, so customer code calling TelemetryConfiguration.CreateDefault() from Global.asax.cs no longer gets an empty configuration. The ApplicationInsightsHttpModule no longer carries the config-reading bookkeeping. TelemetryConfiguration.PrependOpenTelemetryBuilderConfiguration no longer throws if the configuration was already built — it silently skips, so a second TelemetryClient constructed against an already-built configuration no longer throws InvalidOperationException.
