• add distributed tracing support to the tracing HttpModule (#287)
• only extract span context from distributed tracing headers in local root spans (#287)

Builds

Enabling the HTTP module

The HttpApplication integration is not yet enabled by default. To add the tracing HTTP module to your ASP.NET application manually, add the following code to the <system.webServer> element in your web.config file. For more information on adding managed modules to IIS, see the IIS documentation. We will release an update soon that will enable this module automatically.

<system.web>
  <compilation>
    <assemblies>
      <add assembly="Datadog.Trace.ClrProfiler.Managed, Version=0.8.0.0, Culture=neutral, PublicKeyToken=def86d061d0d2eeb" />
    </assemblies>
  </compilation>
</system.web>

<system.webServer>
    <modules>
        <add name="AspNetHttpModule" type="Datadog.Trace.ClrProfiler.Integrations.AspNetHttpModule"/>
    </modules>
</system.webServer>
