Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Now we can use that constant in our GetFilePath method."

A block of code is set as follows:

public string GetFilePath()
{
    string result = _cache.Get(FilePathCacheKey);

    if (string.IsNullOrEmpty(result))
    {
        _cache.Put(FilePathCacheKey, DetermineFilePath());
        result = _cache.Get(FilePathCacheKey);
    }

    return result;
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

public string GetFilePath()
{
    string result = _cache.Get(FilePathCacheKey);

    if (string.IsNullOrEmpty(result))
    {
        _cache.Put(FilePathCacheKey, DetermineFilePath());
        result = _cache.Get(FilePathCacheKey);
    }

    return result;
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "In a direct dependency graph, at compile-time, Class A references Class B, which references Class C"
