CRM 2016 Online Error : Attempt by security transparent method

Posted on by Microsoft Employee

Hello,

I'm using CRM 2016 Online and I want to use JavaScriptSerializer (System.Web.Extensions.dll) but it throws an error like this. Anyone encountered this error ? 

Attempt by security transparent method 'CRMKitchen.CRM.Plugins.CoursePostAsyncCreate.ExecuteCoursePostAsyncCreate(LocalPluginContext)' to access security critical method 'System.Web.Script.Serialization.JavaScriptSerializer..ctor()' failed.

Assembly 'CRMKitchen.CRM.Plugins, Version=1.0.0.3, Culture=neutral, PublicKeyToken=05038d1f23a89c0d' is partially trusted, which causes the CLR to make it entirely security transparent regardless of any transparency annotations in the assembly itself. In order to access security critical code, this assembly must be fully trusted.

Assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf38521ad364e35' is a conditionally APTCA assembly which is not enabled in the current AppDomain. To enable this assembly to be used by partial trust or security transparent code, please add assembly name 'System.Web.Extensions, PublicKey=0024000004800000940000000602000000240000525341310004000001000100B5FC90E7027F67871E773A8FDE8938C81DD402BA65B9201D60593E96C492651E889CC13F1415EBB53FAC1131AE0BD333C5EE6021672D9718EA31A8AEBD0DA0072F25D87DBA6FC90FFD594DA35E44C398C454307E8E33B8426143DAEC9F596836F97C8F74750E5975C64E2189F45DEF46B2A2B1247ADC3652BF5C308055DA9' to the the PartialTrustVisibleAssemblies list when creating the AppDomain.

Note : ILMerge does not work for CRM 2016 Online at least for me.

    The issue is around the code access security attributes for the System.Web.Extensions assembly. I don't think there's any way around this in Crm Online, in which case there's no way to use the System.Web.Extensions assembly in Crm Online
