System.IO.FileNotFoundException With a Plugin

(0) Share

Report

Posted on by Jason Berg

I have written a Plugin in C#. It interacts with a third party web service. I am able to call other search and create methods in the service but there is one call I make that I always get the error message below. I also loose all the trace statements that I have in my code.

Does anyone have any guidance on what to do?

Hi Jason,

I am experiencing a similar problem. I am using CRM 2013 and developing a plugin using Visual Studio 2012. I've added assemblies into my plugin file and am able to use the classes in the plugin fine. When I deploy and trigger the plugin it says that it can't find the file dll file that's referenced in my project. I have also installed the dll files into GAC using the utility, but it still complains that it can't find the dll throwing a System.IO.FileNotFoundException error.

Hi Jason,

In your plugin code :

ProjectorPlugIn.PostProjectorProjectCreate

Do you call any .dll assembly as reference?

Because it is actually can trigger your plugin as well.

Anyway there is a tool to merge the assemblies :

ILMerge.exe

Please refer to this link :

blogs.msdn.com/.../how-to-reference-assemblies-from-plug-ins.aspx

and this

crmdm.blogspot.com/.../crm-cannot-find-plugin-assembly-or-one.html

Hope it helps!

Thanks.

This happens when you use a higher assembly version in your code. For example, If you are registering the plugin for 2013, then do not use the sdk assemblies of 2016 (higher version). You have use the sdk assemblies of the CRM version you're working on.
