Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsAutoClassLPTSTR is interpreted automatically.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsAutoLayoutSpecifies that class fields are automatically laid out by the common language runtime.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsBeforeFieldInitSpecifies that calling static methods of the type does not force the system to initialize the type.

Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsNestedAssemblySpecifies that the class is nested with assembly visibility, and is thus accessible only by methods within its assembly.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsNestedFamANDAssemSpecifies that the class is nested with assembly and family visibility, and is thus accessible only by methods lying in the intersection of its family and assembly.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsNestedFamilySpecifies that the class is nested with family visibility, and is thus accessible only by methods within its own type and any derived types.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsNestedFamORAssemSpecifies that the class is nested with family or assembly visibility, and is thus accessible only by methods lying in the union of its family and assembly.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsNestedPrivateSpecifies that the class is nested with private visibility.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsNestedPublicSpecifies that the class is nested with public visibility.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsNotPublicSpecifies that the class is not public.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsPublicSpecifies that the class is public.
Supported by the XNA FrameworkReservedMaskAttributes reserved for runtime use.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsRTSpecialNameRuntime should check name encoding.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsSealedSpecifies that the class is concrete and cannot be extended.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsSequentialLayoutSpecifies that class fields are laid out sequentially, in the order that the fields were emitted to the metadata.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsSerializableSpecifies that the class can be serialized.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsSpecialNameSpecifies that the class is special in a way denoted by the name.

Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsUnicodeClassLPTSTR is interpreted as UNICODE.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsVisibilityMaskSpecifies type visibility information.
Supported in .NET for Windows Store appsWindowsRuntimeSpecifies a Windows Runtime type.
