Using Tx from LINQPad

LINQPad is the best way to learn the cutting edge features of C#

In the LINQPad experience of Tx is as if all the events were in a Database Except, no database is involved - the the query happens directly on raw logs/traces or real-time sessions

• Getting started with the Tx LINQPad Driver
• Queries on trace from HTTP.sys - the kernel driver used by IIS (Internet Information Services)
• Troubleshooting WCF - using ETW traces (new in .Net 4.5) to understand errors in WCF client-server application
• Average and Deviation. This query is based on .blg file (the default output of PerfMon for counters)
• Cross /provider & cross machine queries. Response time of IE on client machine and IIS on server.
• No Manifest queries. - limited way of using Tx even if you don't have the manifest.

Using Tx from C# code

• When to use Tx? vs. using just LINQ-to-Objects or Rx
• Hello Tx : Building a console app that does query on ETW trace
• Type Generation : How to generate C# types from Manifests and other schema descriptions
• Playback samples : API to replay events from one or more file(s)/session(s) in order of occurrence
• Features of Playback : Multiplexed sequences, Heterogeneity, Same API for past & real-time, etc.
• Synthetic Performance Counters : Defining "counters" as queries on events from ETW real-time session (nothing hits disk)
• Causality Navigation : Infinitely salable troubleshooting from traces on original event sources

Conceptual overviews

• The visual intuition behind the Playback API
• Playback Internals of the Playback
• Extending Tx with semi-structured text logs like SharePoint's ULS format ("Unified Logging Service").
• TimeSource: creation of virtual time from timestamps on the event
