The Prism Template pack, available on Visual Studio Marketplace, offers a collection of helpful snippets to speed up your development. To use the snippets in Visual Studio, simply type the shortcut (e.g. propp) and press TAB.

Here is a quick list of each as a handy reference:

propp

Generate a property with a backing field, that depends on BindableBase. This means it will generate a standard property, but with a setter that uses the BindableBase SetProperty method, e.g.

private string fieldName;
public string PropertyName
{
    get { return fieldName; }
    set { SetProperty(ref fieldName, value); }
}

cmd

Generates a DelegateCommand property, with backing field and the associated Execute method, e.g.

private DelegateCommand _fieldName;
public DelegateCommand CommandName =>
    _fieldName ?? (_fieldName = new DelegateCommand(ExecuteCommandName));

void ExecuteCommandName()
{

}

cmdfull

Generate a DelegateCommand property, with backing field as well as its associated Execute method. It also creates the CanExecute method for you, e.g.

private DelegateCommand _fieldName;
public DelegateCommand CommandName =>
    _fieldName ?? (_fieldName = new DelegateCommand(ExecuteCommandName, CanExecuteCommandName));

void ExecuteCommandName()
{

}

bool CanExecuteCommandName()
{
    return true;
}

cmdg

Similar to the cmd snippet mentioned above, but this one generates a generic DelegateCommand property

private DelegateCommand<string> _fieldName;
public DelegateCommand<string> CommandName =>
    _fieldName ?? (_fieldName = new DelegateCommand<string>(ExecuteCommandName));

void ExecuteCommandName(string parameter)
{

}

cmdgfull

Similar to the cmdfull snippet mentioned above, but this one generates a generic DelegateCommand property with its associated Execute and CanExecute Methods

private DelegateCommand<string> _fieldName;
public DelegateCommand<string> CommandName =>
    _fieldName ?? (_fieldName = new DelegateCommand<string>(ExecuteCommandName, CanExecuteCommandName));

void ExecuteCommandName(string parameter)
{

}

bool CanExecuteCommandName(string parameter)
{
    return true;
}

These snippets are incredibly handy when working with Prism as it really makes it easy to add the code elements essential for the framework to work smoothly.
