BuildManager.AddReferencedAssembly Method

.NET Framework 4.6 and 4.5

Adds an assembly to the application's set of referenced assemblies.

Namespace:  System.Web.Compilation
Assembly:  System.Web (in System.Web.dll)

public static void AddReferencedAssembly(
	Assembly assembly


Type: System.Reflection.Assembly

The assembly to add.


The assembly parameter is null or empty.


The method was not called before the Application_Start event in the Global.asax file occurred.

Calling this method is equivalent to adding the assembly to the application-level Web.config file. The method must be called during the Application_PreStartInit stage of the application.

The GetReferencedAssemblies method will return the set of assemblies that are determined from configuration files and any assemblies that were added by using this method.

If an attempt is made to add an assembly that has already been added, the duplicate entry is ignored.

This method must be called before the Application_Start event in the Global.asax file occurs.

.NET Framework

Supported in: 4.6, 4.5, 4
