The Issue model does not have such properties: Date, ActivityId, Duration, Intensity, Exclude, Notes.

Set up the DTO...
* Add a folder to the root of the "IssueTracker" project named "Dto"
* Add a class to the "Dto" folder named `IssueDto`
* Add properties to the `IssueDto` class using the `Issue` model class as a guide
  * A property of type `int` named `Id`
  * A property of type `DateTime?` named `ReportedOn`
  * A property of type `string` named `Name`
  * A property of type `string` named `Email`
  * A property of type `int?` named `DepartmentId`
  * A property of type `string` named `DescriptionOfProblem`
  * A property of type `Issue.SeverityLevel?` named `Severity`
  * A property of type `bool` named `Reproducible`
* Add `Required` data annotation attributes to the appropriate properties
  * `ReportedOn`
  * `Name`
  * `Email`
  * `DepartmentId`
  * `DescriptionOfProblem`
  * `Severity`
* Add a `MaxLength` data annotation attribute to the `Name` property in order to restrict the length of the value to 100 characters
* Add a `MaxLength` data annotation attribute to the `Email` property in order to restrict the length of the value to 255 characters
* Add a method named `ToModel` that converts the DTO to an instance of the `Issue` model class

Update the IssueController...

Update the `Post` action method to use the DTO...
* Update the `issue` parameter's type to `IssueDto`
* Call the DTO's `ToModel` method to get an instance of a model to pass to the repository's `Add` method
* Set the DTO's `Id` property with the model's `Id` property value after calling the IssueRepository's `Add` method
  * This is necessary to do in order to update the DTO with the ID value that was generated from the database before the DTO is returned to the client

Update the `Put` action method...
* Update the return type to `IHttpActionResult`
* Return a call to the `BadRequest` method if the `ModelState.IsValid` property is false
* Return a call to the `StatusCode` method passing in the `HttpStatusCode.NoContent` enum value
* Update the `issue` parameter's type to `IssueDto`
* Call the DTO's `ToModel` method to get an instance of a model to pass to the IssuesRepository's `Update` method
