Cannot await OpenAccess method

[Richard Harrigan]

Hi
See following line of code in bold that is commented out.  I get the following compile error:
"Cannot await Telerik.OpenAccess.Metadata.MetadataContainer"
If I use "await Task.Delay(2000);"  as show below it works great.  However I can't rely on a fixed amount of time.  Is there any problem awaiting OpenAccess methods or am I doing something wrong?

Thanks
Rich

        public async Task<MetadataContainer> GetSchema(RadBusyIndicator BusyIndicator, ConnectionInfo connInfo, 
            bool TablesAndViews, bool StoredProcedures, bool Indexes)
        {
            ISchemaReader reader = GetSchemaReader(connInfo);
            String[] schemas = reader.GetSchemas();
            SchemaReadParameters readParameters = new SchemaReadParameters(schemas);
            readParameters.Indexes = Indexes;
            readParameters.StoredProcedures = StoredProcedures;
            readParameters.TablesAndViews = TablesAndViews;
            BusyIndicator.IsBusy = true;
            //MetadataContainer metadataContainer = await reader.GetSchema(readParameters); 
            MetadataContainer metadataContainer = reader.GetSchema(readParameters);   
            await Task.Delay(2000);
            BusyIndicator.IsBusy = false;
            return metadataContainer;
        }

Hi Richard,

The ISchemaReader.GetSchema() method doesn't return a Task and is not awaitable. That's why the code you provided won't compile. In order to make to method asynchronous you will have to create a new Task that handles the GetSchema() method. Here is sample code:

var task = Task<MetadataContainer>.Factory.StartNew(() => reader.GetSchema(readParameters));
MetadataContainer metadataContainer = await task;
