We’re just about ready to update our customers from V3.9 to V4.0 finally, but have found issues with deployment on our test server machines. It appears that on some machines KB2468871 patch is necessary while on others it runs without flaws.The error we’re getting is the same as here: http://stackoverflow.com/questions/25859049/servicestack-nuget-update-4-0-22-to-4-0-31-caused-errors-on-deployment
It seems that a pure .NET 4.0 installation does not get the patch automatically, even if Windows update is updating the system regularly. Just to be sure: is it safe to assume that we either need .NET 4.5 full profile or .NET 4.0 plus the additional manual patch KB2468871? Thanks for your help and clarification.
