I am looking to build a fairly simple plug in that calculates the amount of “units” used & remaining.
I have two custom entites bc_learninglicences & bc_llbalance, the plug – in fires on create of bc_llbalance and another for update.
bc_llbalance: Contains
bc_learninglicense (Look up field on bc_learninglicences / bc_name)
bc_units (units that are used by this record)
bc_learninglicences: Contains
bc_name
bc_unitsquantity (This is set to the total qty of units)
bc_unitsused (this needs to inherit the sum of "bc_units" on "bc_llbalance")
bc_unitsremaining ( simply bc_unitsquantity - bc_unitsused )
Ok so I have included the code which is obviously not finished as I have just been trying to figure out how to get bc_unitsused to inherit the sum…
this code builds without error. however CRM errors:
Unexpected exception from plug-in (Execute): LearningLicenses.LearningLicenses: System.IO.FileNotFoundException: Could not load file or assembly ‘Microsoft.Xrm.Client, Version=5.0.9690.2165
I have a short deadline to build this as the system is due to go live soon, however I cannot move forward with this error which I don’t understand…
Either help with error or code/solution will be appreciated at this point as I’m behind on the time frame for this project.
p.s I am new to developing for CRM 2011 with only a few weeks/ few projects experience.

Microsoft.Xrm.Client is not used by CRM and so is not present in the GAC or anywhere on the CRM server, it is intended to be redistributed with any client applications that require it.
It shouldn’t need to be referenced in your Plugin assembly at all, so I would remove it and see if any of your code references it. If it does it should be able to be replaced with equivalent code that doesn’t use that assembly.
