[AX POS 2012] Loading Assembly during runtime through ApplicationTrigger

(0) Share

Report

Posted on by Rune A L

I am trying to load an assembly during runtime, but somehow it fails and I get the following error:

Could not load file or assembly 'file:///C:\Program Files (x86)\Microsoft Dynamics AX\60\Retail POS\FPCreditCard.dll' or one of its dependencies. Operation is not supported. (Exception from HResult: 0x80131515)

I am doing this through reflection:

Assembly ass = System.Reflection.Assembly.LoadFrom("FPCreditCard.dll");

I have been trying to browse the web for any clue as to what the error I get means, but so far I haven't found anything related.

I know the code works because I can run it perfectly on a separate project, so I believe it has something to do with access problems or anything related.

Anyone know what might be the problem here?

I should mention that I am running my windows in testmode to try and remove as much access releated problems, but hasn't worked.

Hello,

in the POS.exe.config in the same folder as your DLL try and set it as:

<?xml version="1.0" encoding="utf-8"?>
<configuration>

<runtime>

<loadFromRemoteSources enabled="true" />

</runtime>

<configSections>

...

I would recommend you save your old pos.exe.config in case this doesn't solve your question.
