Enum | Provides the base class for enumerations. | |
Environment | Provides information about, and means to manipulate, the current environment and platform. This class cannot be inherited. | |
EventArgs | EventArgs is the base class for classes containing event data. | |
Exception | Represents errors that occur during application execution. | |
FormatException | The exception that is thrown when the format of an argument does not meet the parameter specifications of the invoked method. | |
GC | Controls the system garbage collector, a service that automatically reclaims unused memory. | |
INTERNAL_WebRequestHelper |
Gives access to methods to help using WebRequests.
| |
InvalidCastException | The exception that is thrown for invalid casting or explicit conversion. | |
InvalidOperationException | The exception that is thrown when a method call is invalid for the object's current state. | |

MulticastDelegate | Represents a multicast delegate; that is, a delegate that can have more than one element in its invocation list. | |
NotImplementedException | The exception that is thrown when a requested method or operation is not implemented. | |
NotSupportedException | The exception that is thrown when an invoked method is not supported, or when there is an attempt to read, seek, or write to a stream that does not support the invoked functionality. | |
Nullable | Supports a value type that can be assigned null like a reference type. This class cannot be inherited. | |
Object | Supports all classes in the .NET Framework class hierarchy and provides low-level services to derived classes. This is the ultimate base class of all classes in the .NET Framework; it is the root of the type hierarchy. | |
Random | Represents a pseudo-random number generator, a device that produces a sequence of numbers that meet certain statistical requirements for randomness. | |
String | Represents text as a series of Unicode characters. | |
SystemException | Defines the base class for predefined exceptions in the System namespace. | |
Tuple2 |
Utility class that simplifies cration of tuples by using
method calls instead of constructor calls
| |
Tuple2T1, T2 |
Represents a functional tuple that can be used to store
two values of different types inside one object.
| |
Tuple2T1, T2, T3 |
Represents a functional tuple that can be used to store
two values of different types inside one object.
| |
Tuple2T1, T2, T3, T4 |
Represents a functional tuple that can be used to store
two values of different types inside one object.
| |
Type | Represents type declarations: class types, interface types, array types, value types, enumeration types, type parameters, generic type definitions, and open or closed constructed generic types. | |
Uri |
Provides an object representation of a uniform resource identifier (URI)
and easy access to the parts of the URI.
| |
WeakReference | Represents a weak reference, which references an object while still allowing that object to be reclaimed by garbage collection. |

Int64 | Represents a 64-bit signed integer. | |
IntPtr | A platform-specific type that is used to represent a pointer or a handle. | |
NullableT | Represents an object whose underlying type is a value type that can also be assigned null like a reference type. | |
