Yesterday well-known MVP Tanguy Touzard, author of amazing tools for Dynamics CRM 4.0/2011 asked about CallerOrigin property in plugins for Dynamics CRM 2011. This property worked for CRM 4.0 and returned the source of plugin invocation (Application, AsyncService or WebService). I and Gayan suggested to use HttpContext class from System.Web namespace to check source.
Today during debug of one plugin in QuickWatch window I have seen that CallerOrigin property is still in context but it is not property of IPluginExecutionContext:
Following class is helper which allows you easily get origin of plugin invocation:
namespace CallerOrigin.Plugins
{
internal enum CallerOrigin : int
{
Undefind = 0,
Application = 1,
WebService = 2,
AsyncService = 3
}
internal class CallerOriginHelper
{
internal static CallerOrigin GetCallerOrigin(
Microsoft.Xrm.Sdk.IPluginExecutionContext context)
{
if (context.GetType().Name == "SandboxPluginExecutionContext")
return CallerOrigin.Undefind;
object callerorigin =
context.GetType().GetProperty("CallerOrigin").GetValue(context, null);
switch (callerorigin.GetType().Name)
{
case "ApplicationOrigin":
return CallerOrigin.Application;
case "AsyncServiceOrigin":
return CallerOrigin.AsyncService;
case "WebServiceApiOrigin":
return CallerOrigin.WebService;
}
return CallerOrigin.Undefind;
}
}
}
Here is a sample how to use this helper:
var callerorigin = CallerOriginHelper.GetCallerOrigin(localContext.PluginExecutionContext);
Unfortunately this solution works only for plugins that are not registered in Isolation, so for CRM Online it would not work – Undefined value would be returned.
Great!
Thanks Andrii, I will try it next week when returning back to my customer office
Very cool
Then what to do for achieving this in online,please suggest me…
Hello, Unfortunately there it is impossible to make this code work for CRM Online.
Nice simple solution, well done, thanks for sharing.
PS Personally, it works better as an extension method on IPluginExecutionContext, but that's just my preference.
public static CallerOrigin GetCallerOrigin(this IPluginExecutionContext context)
{
if (context.GetType().Name == "SandboxPluginExecutionContext")
return CallerOrigin.Undefind;
object callerorigin =
context.GetType().GetProperty("CallerOrigin").GetValue(context, null);
switch (callerorigin.GetType().Name)
{
case "ApplicationOrigin":
return CallerOrigin.Application;
case "AsyncServiceOrigin":
return CallerOrigin.AsyncService;
case "WebServiceApiOrigin":
return CallerOrigin.WebService;
}
return CallerOrigin.Undefind;
}
Welcome! Unfortunately this is unsupported solution that can be broken with new rollups…
Thanks for good idea!
Hello;
Does this workaround still work for Dynamics365 8.2 (On premise)? I see that the property “CallerOrigin” is still there but I’m wondering how reliable it is.
Hello,
To be honest I believe it’s still reliable but you should remember that this is undocumented so unsupported. You can use it but all risks are on you.
