Debug EF4 SaveChanges in WCF service hosted by IIS

Question

In the existing code the size of transactionEntities is growing and in the almost final statement we\'ve got

Answer 1

For question #1 - you can turn on diagnostics on your WCF service

In your web (or app) config:

1) Add System.Diagnostics section anywhere under configuration element. You can replace path with which ever path you want the files to be stored at.

2) Under system.ServiceModel add following:

3) Under C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\ start SvcTraceViewer.exe. Load both message trace (services_messages.svclog) and service trace log (services_tracelog.svclog). You can either drag drop files in the tool or open one then add another

4) Look for red bold letters for a problem.

If you want to make your experience editing the WCF configuration more palatable you can use SvcConfigEditor.exe which is found under same folder as SvcTraceViewer.exe (#3). Just open the config file and you should see Diagnostics folder which will allow you to start/stop and configure diagnostics.
