hop of those help? You have to explicitly implement the method by adding Implements ITradeViewModel.GetTrades:
code :
    Public Function GetTrades() As ObservableCollection(Of Trade) Implements ITradeViewModel.GetTrades
        If _trades Is Nothing OrElse _trades.Count = 0 Then
            _loadCommand.Execute(_trades)
        End If
        Return _trades
    End Function

Accessing Method from Interface Throwing Conversion Error

Accessing Method from Interface Throwing Conversion Error

To fix this issue You're missing the [Application] attribute on your MyApp class to properly generate AndroidManifest.xml, so Android doesn't know to use that as your application class. Because of that, trying to cast the Application property to MyApp is failing since the object isn't actually an instance of your class. Update your class definition to look like:
code :
[Application]
public class MyApp : Application
{
    // ...
}

this will help I have following classes under different namespaces. I mean, the same 3 classes exist under different namespaces.
code :
public interface iC<T, TI> 
    where T : iB<TI> 
    where TI : iA
{
   List<T> listBinC {get; set; }
}
class C : iC<B, A>
{
    public List<B> listBinC { get; set; }
}

wish help you to fix your issue I'm having an issue when I'm try to iterate through a map of some json. , The error is :
code :
for _, urlItem := range item.(map[string]interface{}){
   do some stuff
}
[map[name:default url:/some/url] map[name:second url:/another/url]]
data := item.([]interface{})
for _,value := range data{
  yourMap := value.(map[string]interface{})
  //name value
  name := yourMap["name"].(string) // and so on
}

I think the issue was by ths following , Given the following interfaces, I don't understand why the second method defined on ITransactionConsumer will not compile. The compiler complains that it is not convertable to ITransaction - but there is a generic constraint that TUser is an IUser..? , Can you replace your offending line with this?
code :
  PaymentSession<TTransaction> ConsumeTransactionWithTUser<TTransaction, TUser>(TTransaction transaction)
     where TTransaction : ITransaction<TUser>, ITransaction<IUser> where TUser : IUser;
  PaymentSession<TTransaction> ConsumeTransactionWithTUser<TTransaction, TUser>(TTransaction transaction)
     where TTransaction : ITransaction<IUser>;

will help you I am trying to decode an arbitrary JSON using Golang, so I unmarshal the incoming JSON in a map[string]interface{} as shown in the code below: , The error says it all:
code :
func otherValues(other interface{}, f *os.File, err error) {
    switch bb := other.(interface{}).(type) {
    case string:
        fmt.Println("This is a string")
    case float64:
        fmt.Println("this is a float")
    case bool:
        fmt.Println("this is a boolean")
    default:
        fmt.Printf("Default value is of type %v", bb)
    }
}
func (f *File) Write(b []byte) (n int, err error)
