System.InvalidOperationException

[Priyavaratharajan]

Hi,
I am getting error in this of code:
private static void ReadLegalEntities(Resources context)
{
Console.WriteLine();
foreach (var legalEntity in context.LegalEntities.AsEnumerable())
{ Console.WriteLine("Name:{0}", legalEntity.Name); }

Error File is about:
An unhandled exception of type ' System.InvalidOperationException' occurred in Microsoft.OData.Client.dll
Additional information: The key property 'Type' on for type
'ProductsApp4.Microsoft.Dynamics.DataEntities.LegalEntityContact' is of
type 'System.Nullable`1[[ProductsApp4.Microsoft.Dynamics.DataEntities.LogisticsElectronicAddressMethodType, ProductsApp4, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]', which is not a simple type. Only properties of simple type can be key properties.

What can you see in ODataClient.cs? Have you tried to recreate the OData client with your D365 for Operations url?

Use the custom OData dlls in https://github.com/Microsoft/Dynamics-AX-Integration/tree/master/Packages
This should solve the issue.

Hi Priya,

Did you able to resolve this issue? If so how did you manage? I am having the same issue.

I tried those DLLs however I'm now getting:

Could not load file or assembly 'Microsoft.OData.Client' or one of its dependencies. Strong name signature could not be verified. The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key.

Any ideas?
