1 of 186 | Screencast: Processing message content with HttpClient - I recently published a new screencast video on Processing message content with HttpClient.  Check out this post for more background.   This screencast shows you how to process different types of messages that you might get back from RESTful services on the Web. It shows how to use XLinq, DataContractSerializer, and XmlSerializer, and it shows how to process XML, Atom, and JSON messages. Check out our growing collection of free .NET screencasts and videos.  You can subscribe to the Pluralsight feed to be notified when new screencasts are published.  In addition, check out our growing library of Pluralsight On-Demand! training courses....

2 of 186 | WCF REST Starter Kit: Paste XML as Types - One of the things people often complain about when building REST clients is the lack of proxy generation support. Although to be fair, it's usually only heard from those coming from a SOAP/WSDL background (some would argue it's completely unnecessary). Achieving this typically requires support for a metadata language like WADL or WSDL 2.0, which are not yet widely supported nor considered standards. The WCF REST Starter Kit Preview 2 provides a nice solution to this dilemma for .NET developers.  They provide a new HttpClient API that provides generic support for the uniform HTTP interface (Get, Post, Put, Delete, Head, etc) that can be used to process a variety of common resour......

3 of 186 | How to create a certificate request with CertEnroll (ASP) - Hi all, The other day I posted a Javascript sample which shows how to use CertEnroll COM component to create a certificate request and install the response from the CA (Certificate Authority): How to create a certificate request with CertEnroll (JavaScript). The installation part of that sample assumed that we got a Base64 text with the response from the CA. But what if we i.e. send the request to a server, the server gets a .p7b or .cer binary file with the response from the CA, and we want to install the response on the client who requested the cert on the first place? The following ASP sample shows how to install on the client the .p7b/.cer binary file that the server got with t......

5 of 186 | Passing Objects via the Azure Message Queue - I have recently been taking a look at Windows Azure Storage, and the use of Blob’s, Queues and Tables. Queues are primarily used for passing small (approx 8kb) messages from the web role of a Azure application to the back end worker role that can then be used to fire off additional processing within the cloud. Using the current StorageClient library that is supplied with the CTP of Azure you can only pass strings as messages from a web role to a worker role by doing the following: 1: Message message = new Message("simple text"); 2: RoleManager.WriteToLog("Information", string.Format("Message '{0}' added to the queue", message.ContentAsSt......

6 of 186 | Boost performance with Pre-generated XmlSerializers - Creating an XmlSerializer has a well-known performance cost since .net will generate a temporary helper assembly which requires a compiler call. Additionally, the assembly cannot be unloaded without unloading the hosting application domain causing high memory usage when several XmlSerializer objects are constructed. Sometimes this assembly-generating process happens in a more indirect manner like the instantiation of a web service proxy class. For example, calling new CrmService() will require an XmlSerializer for the type CrmService which forces .net to generate code, compile and load the assembly. Fortunately, there are alternatives to improve performance and minimize memory usage when c......

7 of 186 | Funq: applying TDD to build a dependency injection container you can understand - I'm planning to record a series of screencasts which will serve as walk-throughs on how to apply TDD on a practical project consisting in building a full-featured and high-performance DI container which has two very explicit goal: minimalistic design and small footprint. Both goals come from the requirements of the project I'm building this for: the upcoming version of the patterns & practices Mobile Client Software Factory. As I've tweeted in the past, the Compact Framework and constrained execution environment of a mobile device, place some requirements on anything you do there, but specially for something which can have a broad impact in performance as a DI container, which typically......

For e.g. suppose you need to read a config file which has the following structure: 1: <MainConfig> 2: <Company>MySpace</Company> 3: <SubConfig> 4: <ID>23</ID> 5: <Name>Rohit</Name> 6: <LastName>Gupta</LastName> 7: </SubConfig> 8: </MainConfig> For this you would create the 2 classes, one for the Parent Config and another for the child config like this: 1: [XmlRoot("MainConfig")] 2: ......

9 of 186 | BitTorrent in the Browser - Opera does it. Others talk about it. Robert Accettura posts about how he thinks we should implement BitTorrent in the browser. He doesn't want a X-Torrent HTTP header as we can use Accept-Encoding for the same goal. How would it work? Assume my browser supports the BitTorrent protocol and I visit the following URL for a download: http://dl.robert.accettura.com/pub/myfile.tar.gz My request would look something like this: Get: /pub/myfile.tar.gz Host: dl.robert.accettura.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5 Accept: */* Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate,torrent Accept-Charset: ISO-8859-1,utf-8;q=......

12 of 186 | Fault Serialization with XmlSerializer - About 20 posts ago, back before PDC, this was the next topic in the queue to be posted. It has been somewhat delayed by all of the talk of product announcements and details about future releases. Since it was becoming lonely and forgotten I thought I'd get back onto talking about the product that you're actually using. I think I'm going to keep the style of not linking continuity between posts. No one complained when the forward references went away and it seems to make the posting schedule a bit more flexible to accommodate announcements and current events. I'm using XmlSerializer for my messages but when I send a fault by throwing a FaultException, the fault exception detail gets......

13 of 186 | New additions in 3.5 Sp1 - In .NET 3.5 SP1 the following features are added to the DataContractSerializer. 1. Support for POCO types. Aaron has a nice writeup here. I have updated my post on Serialization Rules to include this. 2. Support for get-only collection properties. 3. Support for schema-verifiable multiple object reference (i.e using the same instance of an object in two places) Another new feature worth mentioning is the support of XmlSerializer for serialization of faults. I will write more about each of these features in the near future....

14 of 186 | The $64 String... - With apologies to the game show... I was working on a cryptography project, and, without going into detail (it's SECRET, duh), I was having some issues. The other party sent me their test key in a text file, and it was Base64 encoded. Naturally, being the smart id10t that I am, I popped open my handy dandy, Base64 decoder site, decoded the string, and placed the string in the proper location for it to be used in the decoding process. Lo and behold the decryption process broke...because the key was too small! In my investigation, it turns out that decoding it by any means other than Convert.FromBase64String() resulted in a byte array with only 31 bytes. Since a 256-bit key requires a 32-......

16 of 186 | NAV 2009 and Unicode! - The title might be a bit misleading, but I am writing this post as a response to a problem, which a partner ran into with NAV 2009 - and the problem is caused by Unicode. I am not a Unicode expert, so bare with me if I am naming some things wrong. As you know, NAV 2009 is a 3T architecture and the Service Tier is 95% managed code (only the lower pieces of the data stack is still unmanaged code). You probably also know, that managed code supports Unicode natively - in fact a string in C# or VB.Net is by default a Unicode string. In C# you use byte[] if you need to work with binary data.

19 of 186 | Serializing internal types using XmlSerializer - Being able to serialize internal types is one of the common requests seen by the XmlSerializer team. It is a reasonable request from people shipping libraries. They do not want to make the XmlSerializer types public just for the sake of the serializer. I recently moved from the team that wrote the XmlSerializer to a team that consumes XmlSerializer. When I came across a similar request I said, "No way. Use DataContractSerializer".   The reason is simple. XmlSerializer works by generating code. The generated code lives in a dynamically generated  assembly and needs to access the types being serialized. Since XmlSerializer was developed in a time before the advent of lightweight ......

21 of 186 | WMRM SDK 10.1.2 best practice sample code - I wrote this sample code a while back to show how to validate the latest individualization version when using predelivery. Here are a few tricks that you need to do to make this work. Namely, you need to parse the “ClientInfo” XML fragment the hard way. This sample code shows you how to do just that. The documentation below is a complete walkthrough of the code but the code is also well documented. This is a great place to start if you are trying to do WM DRM predelivery form ASP.net. Keep in mind that this code will only work with the WMRM SDK version 10.1.2 or better. Older versions of the SDK may not work as expected. If you have an older version of the SDK you may need to modify the cod......

22 of 186 | Getting Better Time Formats - Orcas introduced a new DateTimeOffset class that is easier to use for representing absolute times than the original DateTime class. However, if you run svcutil on a contract that contains a DateTimeOffset, you'll get an ugly generated structure because DateTimeOffset isn’t recognized as a natively supported type by the system. A new class is generated by svcutil to match the schema for DateTimeOffset in the metadata. namespace System { using System.Runtime.Serialization; [DebuggerStepThroughAttribute()] [GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")] [DataContractAttribute(Name="DateTimeOffset", Namespace="http://schemas.datacontract.org/2......

26 of 186 | XmlSerialization to generate and consume XML - I want to talk about Xml Serialization this month. One of the work I was involved in recently required generation of XML and a I came across this wonderful technology which helps you generate and consume XML seamlessly.   If you are generating XML in a clumsy way using printf containing the XML tags, I would strongly suggest you to look into this technology. Incidetaly this plays well with Linq too. The XML after it is loaded into the object can be parsed with Linq queries.

27 of 186 | Serialization using XElements - Introduction I recently starting fooling around with the new XML LinQ stuff in .Net, and it is very impressive. One thing that I found missing was the ability to serialize objects directly into XElements. However, Microsoft did provide the means to get me to hit the ground running and it took a couple of minutes for me to get it right. Readers and Writers One thing the classical .Net XML always lacked was an "XmlNodeWriter", a writer that basically allows you to create DOM XML nodes using a standard XmlWriter. There are several implementations, but they can only insert nodes into a document (or a node within that document). Microsoft has now filled that gap with the XNode.CreateReader()......

29 of 186 | Serializable XmlDocument - It's surprising that XmlDocument isn't marked [Serializable], because it's very natural to serialize one into a stream. I wanted to put an object into ASP.NET ViewState the other day, and quickly ran into this roadblock, because part of the object included an XmlDocument, which is not serializable. A quick search revealed that most people deal with this problem by storing a string instead. Indeed, that was where I started, but I quickly realized that there are multiple places in my code where I want to do this sort of thing, and I don't want to have to mess with it in each data structure that contains an XmlDocument. So I put together a simple class that holds an XmlDocumen......

Enter.. JSONVid. Using a player like mplayer, it is easy to export all frames in a movie clip to individual jpeg files, and using whichever language you prefer it is also fairly trivial to collect these files, base64 encode the bunch of them and throw them all together in a nice JSON file (I used this PHP script).

49 of 186 | Use of SGEN.exe to avoid common XmlSerializer performance pitfalls - This week, I encountered a test scenario which makes use of an XmlSerializer on it's startup path. Unfortunately, MSDN's documentation for the type is not clear on the performance impact of using an XmlSerializer. The documentation on introducing XML serialization, found here, actually mentions the solution, but it also does not state what the problem is. When you use an XmlSerializer, a helper assembly(1) with a custom type for serializing your type is created. The C# CodeDom is used to generate this code, which then is compiled by the C# compiler. The runtime must then load this generated assembly, and JIT the code. Additionally, a separate assembly is generated for each type you create ......
