ExecutePluginWith<T>(...) has no parameter for MessageName - need to use obselete method ExecutePluginWithTargetAndPreEntityImages<T>(...)

[thomas-schiller]

My PostUpdate plugin uses a preImage.
I need to set the PreImage for my plugin execution. I don't see any possiblity to pass an PreImage AND set the message name to "Update" (always default--> "Create")

Hence I am forced to use the obsolete method "ExecutePluginWithTargetAndPreEntityImages". The obsolete warning tells me to use "ExecutePluginWith", but I don't find any possiblity to set the message name.
Am I wrong?

Hi Thomas,

It is indeed possible. You can use the GetDefaultPluginContext method to retrieve a default context and override whatever is needed before passing it into the ExecutePluginWith method, including setting any PreEntityImages you want as well as the message name:

fake-xrm-easy/FakeXrmEasy.Shared/XrmFakedContext.Plugins.cs

Lines 23 to 32 in 486c7ff

	MessageName = "Create",
	UserId = userId,
	BusinessUnitId = businessUnitId,
	InitiatingUserId = userId,
	InputParameters = new ParameterCollection(),
	OutputParameters = new ParameterCollection(),
	SharedVariables = new ParameterCollection(),
	PreEntityImages = new EntityImageCollection(),
	PostEntityImages = new EntityImageCollection(),
	IsolationMode = 1

Also, you might want to take a look at the later version cause v1.x is deprecated and will stop receiving updates soon....

Feel free to ping me if you still have questions.

I'm also adding a sample using that approach, not necessarily for PreEntityImages but other InputParameters, although it should work as well:
