Remarks

Note

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

This ITypeProvider implementation, in addition to handling compiled assemblies (AddAssembly and AddAssemblyReference methods), can handle types that have not been compiled yet (AddCodeCompileUnit). The limited implementation of System.Type is returned for types referenced using CodeCompileUnit.

Note

TypeProvider only returns public types from referenced assemblies, and both public and non-public types from local assemblies.

Constructors

Name	Description
TypeProvider(IServiceProvider)	Initializes a new instance of the TypeProvider class.

Properties

Name	Description
AssemblyNameResolver	Gets or sets the delegate that references a method with one parameter and one return value that returns the assembly display name in which a specified type belongs to.
IsSupportedPropertyResolver	Gets or sets the delegate that references a method with two parameters and one return value that determines whether a specified property is supported in the target .NET Framework.
LocalAssembly	Gets a value that represents the locally defined Assembly for this instance.
ReferencedAssemblies	Gets a collection of all assemblies referenced by the Type.
TypeLoadErrors	Gets an IDictionary of load error exceptions keyed by the Object that causes the Exception.

Methods

Name	Description
AddAssembly(Assembly)	Adds an already-loaded assembly. It is the caller's responsibility to load the assembly, and TypeProvider includes the types from this assembly for dispensing when GetType is called.
AddAssemblyReference(String)	Adds a reference to the Assembly to the internal list. This assembly is used for the Type lookup in the GetType(String) method.
AddCodeCompileUnit(CodeCompileUnit)	Adds a reference to the CodeCompileUnit to the internal list. This
