Initializes the Component with strict assembly resolution rules

Namespace: Microsoft.Activities.Extensions
Assembly: Microsoft.Activities.Extensions (in Microsoft.Activities.Extensions.dll) Version: 2.0.6.9 (2.0.6.9)

Syntax

C#
public static bool InitializeComponent<T>( T component, string resourceName, IList<string> assemblies ) where T : Activity

Visual Basic
Public Shared Function InitializeComponent(Of T As Activity) ( _ component As T, _ resourceName As String, _ assemblies As IList(Of String) _ ) As Boolean

Visual C++
public: generic<typename T> where T : Activity static bool InitializeComponent( T component, String^ resourceName, IList<String^>^ assemblies )

Parameters

component: Type: T
The component.

resourceName: Type: System..::..String
The resource Name.

assemblies: Type: System.Collections.Generic..::..IList<(Of <(<'String>)>)>
The referenced assemblies.

Type Parameters

T: The type of activity you are initializing

Return Value

true if content loaded

Remarks

The InitializeComponent method generated by the XamlAppDef build task uses a version independent loading strategy for referenced assemblies. This helper method will ensure that only assemblies provided in the assemblies list will be loaded.

Examples

A overloaded constructor that accepts a XamlAssemblyResolutionOption
