GDPR and disabling Sitecore Tracker lead to Exception in Sitecore.Analytics.Media.MediaRequestEventHandler.OnMediaRequest
As many Europe-based businesses we had to comply with GDPR legislation, which requires us to not track analytical data from visitors without their consent.

The Ultimate XConnect Troubleshooting Guide
Many of us have been there: whether it's a matter of containerizing an existing solution, moving an instance to a different machine, or even just setting up our local development environment, many Sitecore developers had to square off with a non-functional XConnect instance. Last week was the third time in my career, so I decided […]
XConnect on Windows 11: ERR_CONNECTION_RESET error when using HTTPS
Problem This week I moved my local development Sitecore 10 instance to a new laptop running Windows 11; all seemed well, except for XConnect, that mysteriously only worked without HTTPS. I would constantly get ERR_CONNECTION_RESET, with nothing being recorded in either XConnect, IIS or Events log: All the while the TLS Certificate was reported invalid. […]
CS0012: The type 'System.Object' is defined in an assembly that is not referenced.
I was setting up my Sitecore instance(s) on a new laptop, when this error reared its ugly head and kept me stuck for a good hour. Looking online there are many reasons why this showed up, but in my case, all I had to do was adding this line under configuration/system.web/compilation/assemblies: <add assembly="netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51"/> […]

Searching for this error in relation to Sitecore usually points to Newtonsoft.Json.dll as the culprit, but in my case it was Mvp.Xml.dll, that some NuGet or somesuch upgraded to a higher version thus causing this error. I reverted […]
Custom fields in Solr 7.2.1: how to reuse your old schema.xml file from previous versions
My Sitecore 8.1 solution has a considerable number of Custom fields; after the upgrade to Sitecore 9.1 (and Solr 7.2.1), none of them worked the way they did, returning an "unknown field" error for any field that used a custom <dynamicField>. What I ended up doing, was adding the node under <config> in […]
Random error after upgrading some NuGet packages: "You must add a reference to assembly 'netstandard, Version=2.0.0.0"
Just a very quick write-up on this as it kept me busy for a couple of hours looking for a solution. After upgrading a number of NuGet packages (Microsoft ASPNet WebApi 2.2 Core Libraries, Microsoft ASPNet MVC, HtmlAgilityPack), my perfectly working Sitecore local development setup stopped working, instead throwing the exception CS0012: The type 'System.Object' […]
