Hi @jordimontana82 I am having some errors because DeleteRecordChangeHistory was added in the v9.0.1.0

9.0.1.0: UR1 (Update Rollup 1)
   Added DeleteRecordChangeHistory message to delete audit change history for a particular record

How could I say to my tests not to include this if it doesn't exist? Do you have any example?
CC @BetimBeja just in case you had the same issue before and you could help me.

I made a PR victorsolaya#1 to your repository which will update this PR if merged.
Each build of FakeXrmEasy defines a symbol for the dependency it has on the specific version of the CrmSdk. When there are braking changes we can use those symbols in the #if directives to handle the missing dependencies.

Thanks both for this.
