Unity Services

Hello,

we have a crash in our UWP build caused by the following exception when intiializing Unity IAP (.NET backend):

This is the code triggering it:

var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
builder.Configure<IMicrosoftConfiguration>().useMockBillingSystem = true;

builder.AddProduct("my_product_id", ProductType.Consumable);

UnityPurchasing.Initialize(this, builder);

Thank you

Hi @ung ,

Would you be able to provide some more information about this issue?

What device and OS version do you see this issue on?
Are you able to reproduce this issue with a new project and your IAP implementation?

If you could provide that information, we would be able to provide further assistance.

Hi @ap-unity

Fortunately we solved the issue. It was an error on our side, we had a modified C# project that wasn’t referencing all the required dlls.

Thank you very much for your interest
