'Declaration
Public Property DotNetAssemblyName As String
    Get
    Set
'Usage
Dim instance As BusinessLogicHandler
Dim value As String

value = instance.DotNetAssemblyName

instance.DotNetAssemblyName = value

public string DotNetAssemblyName { get; set; }

public:
property String^ DotNetAssemblyName {
    String^ get ();
    void set (String^ value);
}

member DotNetAssemblyName : string with get, set

function get DotNetAssemblyName () : String
function set DotNetAssemblyName (value : String)

Property Value

Type: System.String
A String value that specifies the assembly name.

Remarks

The value set for DotNetAssemblyName must include the full path to the assembly, unless the assembly is registered in the global assembly cache (GAC), deployed in the same directory as the Merge Agent executable, or deployed in the same directory as the application that synchronously invokes the Merge Agent.

The DotNetAssemblyName property must be set before calling RegisterBusinessLogicHandler.

Any user can retrieve or set the DotNetAssemblyName property.
