Make sure to replace [ with LESSTHAN and ] with GREATERTHAN symbol.

In this video, we will discuss, detecting errors in views at compile-time rather than at run-time.

The following code will display employee’s FullName and Gender. Here we are working with a strongly typed view. Employee is the model class for this view. This class has got “FullName” and “Gender” properties.

For example, if you mis-spell FullName property as shown below, and when you compile the project, you wouldn’t get any compile time errors.
@Html.DisplayNameFor(model =] model.FullName1)

You will only come to know, about the error when the page crashes at run-time. If you want to enable compile time error checking for views in MVC
1. Open MVC project file using a notepad. Project files have the extension of .csproj or .vbproj
2. Search for MvcBuildViews under PropertyGroup. MvcBuildViews is false by default. Turn this to true as shown below.
[MvcBuildViews]true[/MvcBuildViews]
3. Save the changes.

If you now build the project, you should get compile time error.

Please Note: Pre-compiling views is different from compile-time error checking. We will discuss pre-compiling views in a later video session.
