The FCL does offer a SystemSerializableAttribute type, and an instance of this type is being applied to SomeType Because the Serializable attribute is common, it is compiled into the metadata as a bit: the full metadata for an instance of the Serializable attribute won t be emitted to the metadata This is why these attributes are called pseudo custom attributes: they look like regular attributes and you apply them in source code just as you do regular attributes, but they are persisted in a super compressed way (as a bit) The important point to remember about pseudo custom attributes is that you can t detect their presence at run time in the same way you detect the presence of regular custom attributes In a previous code example, I applied the Serializable and DefaultMemberAttribute attributes to the App type However, when the application runs, only the DefaultMemberAttribute is displayed.

Methods such as IsDefined, GetCustomAttributes, and GetCustomAttribute don t work with pseudo custom attributes Ideally, the NET Framework team would have hidden the fact that pseudo custom attributes are handled differently than regular attributes And in future versions of the NET Framework, they might You can employ other means to detect the use of these pseudo custom attributes For example, SystemType offers read only properties such as IsSerializable, IsAutoLayout, IsExplicitLayout, IsLayoutSequential, and more And SystemReflectionFieldInfo offers read only properties such as IsNotSerialized However, for most pseudo custom attributes, there are no types or methods defined in the FCL that allow you to detect the presence of a pseudo custom attribute (By the way, there is a way to detect pseudo custom attributes if you resort to unmanaged code and access the CLR s COM interface directly) Here s a list of the .

Temporary tables are created in tempdb, regardless of the database context of your session . They have physical representation in tempdb, although when they re small enough and Microsoft SQL Server has enough memory to spare, their pages reside in cache . SQL Server persists the temporary table s pages on disk when there is too little free memory . Furthermore, tempdb s recovery model is SIMPLE and cannot be changed . This means that bulk operations against temporary tables can benefit from minimal logging . Also, SQL Server supports a deferred drop feature in tempdb . When the application drops a large temporary table SQL Servers defers the drop activity to a background thread, so the application can continue working immediately . Unlike user databases, tempdb is created from scratch as a copy of the model database every time you restart SQL Server, hence there s no need for a recovery process in tempdb . This fact leads to optimizations that you can benefit from when modifying data in tempdb

Notice that for the center row and column, you are setting the Height and Width properties to "*". The asterisk tells the row and column to take up all available space. As the Grid control is resized with the browser window, those columns will be resized to take up all the space not consumed by the fixedsized columns. After you have added these row and column definitions, your canvas should appear as shown in Figure 3-13.
