Microsoft.Crm.ObjectModel.MultiCurrencyPlugin

Today I faced an error which took me about three hours to solve it, that messsage appeard when I tried to save a record which I was sure there was no plugins running against it.

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: An unexpected error occurred.Detail:

I rummaged the whole internet trying to find out the cause of that issue without luck, people on the internet say that it's caused by currency field stuffs, however it wasn't in my case.

Tired I curiously went to check out plugin registration Assemblys, that's when I noticed that the following steps were disabled (don't ask me why).








Enabling those steps solved my problem.

Hope it helps someone else.

Invalid where condition. An entity member is invoking an invalid property or method

I had recently been requested to perform a query in Dynamics CRM database using Linq without EntityGeneratedCode aid, that's when I came up with this error: "Invalid 'where' condition. An entity member is invoking an invalid property or method.".

I thougth it was some syntax error I had gotten, however it was not. Take a look at the code at this moment.

  Guid id = new Guid("2C2B13B2-E881-E311-93FA-00155D1E6428");
   var query = from c in orgContext.CreateQuery("account")
                     where ((EntityReference)c.Attributes["accountid"]).Id == id
                     select c;

With some help I found out that it's a frequent error when using linq. It's pretty easy to solve that, I just had to put off the "Attributes" string from the query. So it's like that right now.

 Guid id = new Guid("2C2B13B2-E881-E311-93FA-00155D1E6428");
  var query = from c in orgContext.CreateQuery("account")
                    where ((EntityReference)c["accountid"]).Id == id
                    select c;

I still don't know why it must be this way, but anyway, that's the way I found to fix that.
