  Box 1: IsBlank

  The IsBlank function tests for a blank value or an empty string. The test includes empty strings to ease app creation since some data sources and controls use an empty string when there is no value present.

  Box 2: IsType

  The IsType function tests whether a record reference refers to a specific table type.

  Box 3: AsType

  The AsType function treats a record reference as a specific table type, sometimes referred to as casting. You can use the result as if it were a record of the table and again use the Record.Field notation to access all of the fields of that record.

  An error occurs if the reference isn't of the specific type.

  Correct Answer:

  

  Explanation:

  Box 1: Change the code at line CS104 to query.CoumnSet = AllColumns

  Scenario: Error Message: il-specify-column

  Symptoms

  Retrieving all columns can cause:

  Performance issues due to the amount of data being retrieved

  Unintended plug-in/process execution

  Guidance

  For optimal performance, you should only select the minimum amount of data needed by your application when querying Microsoft Dataverse data.

  ColumnSet Parameter

  When you use the IOrganizationService.Retrieve method set the columnSet parameter to a ColumnSet instance with specified columns. When you use QueryExpression set the ColumnSet property with the required attributes.

  Box 2: Add the following code at line CS203: request.KeepAlive =false;

  Scenario: Error message: Il-turn-off-keepalive

  Symptoms

  If a plug-in makes external web requests and is trying to use KeepAlive on a closed connection, the plug-in will ultimately fail to execute the web request. If the plug-in is registered:

  Synchronously, users may experience:

  Unresponsive model-driven apps

  Slow client interactions

  The browser stops responding

  Asynchronously, plug-in executions may take an extended period of time before failing.

  Guidance

  In HTTP 1.1, all connections are considered persistent (KeepAlive is true) unless declared otherwise. Due to the fact that plug-ins run in isolation, the Sandbox service translates into them being short-lived executions that generally would not

  benefit from KeepAlive. To avoid problems with connecting to external services we recommend disabling KeepAlive within plug-ins. This is done by setting KeepAlive to false.
