When working on Sitecore and deploying modules to a Sitecore site we only want to deploy artifacts that are ours and not from Sitecore. This way we want to keep the deployment packages clean and fast. To manage the contents and behaviors of deployment packages we can use a wpp.targets file. The project setup We use Unicorn to serialize […]
You probably have on sites with pages that show how often these are visited. This is done to show visitors that the page has attracted more people to read it and encourages them to read the article as well. This blogpost has been written using Sitecore 8.2. In older versions of Sitecore, different solutions can be used. […]
MVC5 came with some really nice stuff. In this blog post I’ll dig into the authentication with external logins as Microsoft calls them. We call them often social logins. The way this is done is quite different than in MVC4. Where MVC4 depended on webmatrix MVC5 makes use of OWIN security
Recent in my project we had a problem with a TFS build when calculating the code metrics of the code. The error we ran into was the CA0055 Could not load file. Searching on the internet gave me some hints but not the solution in my case.

When working with generated code, I don’t want this to affect my code coverage, code metrics or code analysis. All these statistics are interesting over code that really matters. To exclude generated code from these statistics you can use a few attributes. GeneratedCodeAttribute, this will exclude the code for code metrics and code analysis. It […]
WCF client cannot be used inside a Using block because they may unexpectedly throw an exception. Even if you catch the exception, it is possible that a connection will be left open.

Using the SharpZipLib it’s possible to zip and unzip files. This can be a good solution when file size matters. Downloading files that are ziped can save many bandwidth. In this case a object is serialized to XML and put into a ZipOutputStream which belongs to SharpZipLib. public static byte[] RetreiveBytes(IEnumerable<int> Ids) { MemoryStream stream […]
The XmlSerializer can cause serious problems in multithreaded environments. See this piece of code. [ThreadStatic] private static XmlSerializer xmlSerializer = new XmlSerializer(typeof(Mailpack), Namespace); private static string SerialiseAssemblageResultaat(Mailpack mailpack) { StringBuilder xmlString = new StringBuilder(); TextWriter xmlWriter = new StringWriter(xmlString); try { xmlSerializer.Serialize(xmlWriter, mailpack); return xmlString.ToString(); } finally { xmlWriter.Close(); xmlWriter.Dispose(); } } What we see […]
