    Guid extensionClassId
)

static member RemoveExtension : 
        element:ModelElement * 
        extensionClassId:Guid -> bool

public static function RemoveExtension(
    element : ModelElement,

) : boolean

Parameters

element

The element whose extension is to be removed

extensionClassId
Type: System.Guid

Return Value

Type: System.Boolean
true if an extension of the particular type was found and removed, else false

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type ModelElement. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

Note that assuming the Extensions collection is maintained through the Extensibility API then there can be only one extension of a particular type present, so only the first found is removed.
