Dynamics CRM Microsoft.IdentityModel exception in Windows 10

When trying to connect to Dynamics CRM services on a Windows 10, machine, you might get this error:

Could not load file or assembly ‘Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35’ or one of its dependencies

There are plenty of blog posts around that will all tell you to go and install "Windows Identity Foundation", however this is no longer the case for Windows 10 and the installer for WIF will fail.  This is because it's now a Windows feature - install it via the "Turn Windows features on or off" section in "Programs and Features" as mentioned here.

Using WiX to create an event source during install of a .NET framework project

Edit: so I guess I wasn't the only one confused with this stuff, as it's been my most popular post by far!  If I've helped you out or saved you some time, please let me know in the comments :)

In order for this to work, you have to add references to WixUtilExtension and WixNetFxExtension to your WiX project.  Once that's done, add this inside a <Component> element:

<Util:EventSourcexmlns:Util="http://schemas.microsoft.com/wix/UtilExtension"Name="EVENTSOURCEGOESHERE"Log="Application"EventMessageFile="[NETFRAMEWORK40FULLINSTALLROOTDIR]EventLogMessages.dll" />
Obviously replace EVENTSOURCEGOESHERE with your event source name.  NETFRAMEWORK40FULLINSTALLROOTDIR is a property set by the WixNetFxExtension which stores the path to the .NET framework v4 directory, but you can replace this with the corresponding property for the directory containing the relevant EventLogMessages.dll file.  So if you're using the .NET framewo…

Using Log4Net to use both event log and a rolling log file

Here's the config section, note that the applicationNameproperty in the EventLogAppender needs to be the same as the event source in the windows event log that you want to log to.  If the event source doesn't exist, that appender won't work.  In this particular project I create that during install using WiX (which is covered in another post)

  <log4netdebug="true">

"A section using 'configSource' may contain no other attributes or elements" error after installing Application Insights

After installing the Application Insights nuget package to an Umbraco solution, you'll get this error:

A section using 'configSource' may contain no other attributes or elements

<ExamineLuceneIndexSets configSource="config\ExamineIndex.config" />
     <log4net configSource="config\log4net.config">
         <root>
             <level value="ALL" />
             <appender-ref ref="aiAppender" />
Source File: \project\web.config

This happens because part of the Application Insights installation process adds a <log4net> section to web.config.  Which would make sense, except Umbraco already has a <log4net> section in /config/log4net.config.  So as you can imagine, the solution is to manually move everything its added into that file. Unfortunately you can't just copy/paste the whole lot, but it's not particularly complicated:


Move <appender-ref ref="aiAppender" /> into the lo…
