We are doing automatic Azure deployments (blue/green) with .update package installations. We are using Octopus deploy to Azure, with remote Powershell script to install the .update package and do a smart publish. We deploy code, restart the app service similar to recycling the apppool, kick off .update package install and publish. We are getting the following error:
The type initializer for 'Sitecore.Install.Serialization.IOUtils' threw an exception.
If we go to the site manually, and try to install it as package thru the package installer, we get the same error. This seems to go away if we wait x amount of time. We can then install a package again.
ITHit.WebDAV.Server.dll was in the bin folder. Does anyone have an idea what else it could be? Thanks.
