Building on the presentation from last week in Antwerp I give this session here in Stockholn at the Swedish TechDays.
In this lecture I address some problems that may occur with WCF and present possible solutions to them. In addition, there are also some smaller but powerful tips which you may just want to try out.
Here is the outline of the topics (again, this is just a selection of tips, we have more in the pipeline, maybe at other conferences) and the list of questions/problems being addressed.
Please feel free to download the PDF and the sample code at the end of this post.
- Consuming
- Do I always need to create a proxy class from WSDL/MEX?
- How can I make consuming services more robust?
- Is there a way to improve performance when calling services?
- How can I call in-process ‘services’ and WCF services in the same way?
- Hosting
- Which host to use? IIS/WAS or a self-host?
- How do I inject logic in IIS/WAS hosting?
- Bindings
- My WCF service is slow, what is happening?
- I want to use HTTP but not necessarily angle brackets (aka ‚XML‘)
- How can I choose from the best communication options?
- Quotas & throttles
- Beyond Hello World, all my services and consumers fail with strange exceptions
- My services do not perform the way they are supposed to
- How can I teach WCF to be less ‘conservative’ in Intranet environments?
- Metadata & WSDL
- Some non-WCF consumers cannot understand the WSDL WCF produces
- My WSDL contains the wrong host name
- I cannot use multiple IIS web site bindings with my WCF services
- Large data
- My service eats a lot of memory and chokes the CPU when sending/receiving large data
- Bigger messages are making my communication really slow
- I have arbitrary, non-structured data to transfer
- Performance
- Somehow my entire WCF-based application is ‚slow‘
- Hosting my WCF service in IIS seems not to perform well under high load
- I cannot seem to get a high throughput when clients talk to my service via HTTP
- All that data is being transferred again and again, it makes my system slow
- Tracing
- Some rarely known tip here

Reformulate the usual consensus thus:
"a vice presidential choice has little effect on election outcome *unless* it casts serious doubt on the judgment of the presidential candidate"
and you will find it is consistent with 2008 as well as past experience.

I've been reading your post and I think have very good information, I would like to know the methodology you use to write your post.
