Could not load file or assembly ‘Microsoft.Cloud.InstrumentationFramework.Events’

October 23, 2016 2 comments

I got the below assembly load error, while I was running my ADX Portal web site from Visual Studio.

Could not load file or assembly ‘Microsoft.Cloud.InstrumentationFramework.Events’ or one of its dependencies. An attempt was made to load a program with an incorrect format.



Issue was not with missing .dll reference, as I already had the “Microsoft.Cloud.InstrumentationFramework.Events.dll” added to my project.


  • Enabling an option in my Visual Studio Project fixed the issue.
  • Navigate Tools -> Options -> Project and Solutions
  • Enable “Use the 64 bit version of …” option.
Use 64 bit version

Use 64 bit version

  • Build and run the Project.
