    Public Properties
     NameDescription
    Public PropertyProvides access to the FluentAssertions.Execution.AssertionChain that this assertion class was initialized with. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)
    Public PropertyGets the IMonitor<T> which is being asserted.  
    Public Property Gets the object whose value is being asserted. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)

    Protected Properties
     NameDescription
    Protected PropertyOverridden.  Returns the type of the subject the assertion applies on. It should be a user-friendly name as it is included in the failure message.

    Public Methods
     NameDescription
    Public MethodOverloaded. Asserts that the object is assignable to a variable of type T. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)
    Public Method Asserts that the current object has not been initialized yet. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)
    Public MethodOverloaded. Asserts that the object is of the specified type T. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)
    Public Method Asserts that an object reference refers to the exact same object as another object reference. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)
    Public Method (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)
    Public MethodOverloaded. Asserts that the predicate is satisfied. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)
    Public MethodOverloaded. Asserts that the object is not assignable to a variable of type T. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)
    Public Method Asserts that the current object has been initialized. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)
    Public MethodOverloaded. Asserts that the object is not of the specified type T. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)
    Public Method Asserts that an object reference refers to a different object than another object reference refers to. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)
    Public Method Asserts that an object has not raised a particular event.  
    Public MethodAsserts that an object has not raised the System.ComponentModel.INotifyPropertyChanged.PropertyChanged event for a particular property.  
    Public Method Asserts that an object has raised a particular event at least once.  
    Public MethodAsserts that an object has raised the System.ComponentModel.INotifyPropertyChanged.PropertyChanged event for a particular property.  
    Public MethodAllows combining one or more assertions using the other assertion methods that this library offers on an instance of T. (Inherited from FluentAssertions.Primitives.ReferenceTypeAssertions<T,EventAssertions<T>>)

    Extension Methods
     NameDescription
    Public Extension MethodSafely casts the specified object to the type specified through TTo.
    Public Extension MethodOverloaded. Invokes the specified action on a subject so that you can chain it with any of the assertions from FluentAssertions.Specialized.NonGenericAsyncFunctionAssertions
    Public Extension MethodOverloaded. Forces enumerating a collection. Should be used to assert that a method that uses the yield keyword throws a particular exception.
    Public Extension Method Provides methods for asserting the execution time of a method or property.
    Public Extension MethodOverloaded. Invokes the specified action on a subject so that you can chain it with any of the assertions from FluentAssertions.Specialized.ActionAssertions
    Public Extension MethodOverloaded. Starts monitoring eventSource for its events.
    Public Extension MethodOverloaded. Returns an FluentAssertions.Specialized.ExecutionTimeAssertions object that can be used to assert the current FluentAssertions.Specialized.ExecutionTime.
    Public Extension MethodOverloaded. Returns an FluentAssertions.Primitives.EnumAssertions<TEnum,TAssertions> object that can be used to assert the current TEnum.
