AppDomainSetup.DisallowApplicationBaseProbing Property


Specifies whether the application base path and private binary path are probed when searching for assemblies to load.

 property bool DisallowApplicationBaseProbing { bool get(); void set(bool value); };
public bool DisallowApplicationBaseProbing { get; set; }
member this.DisallowApplicationBaseProbing : bool with get, set
Public Property DisallowApplicationBaseProbing As Boolean

Property Value


true if probing is not allowed; otherwise, false. The default is false.


If the DisallowApplicationBaseProbing property is true, the value of the ApplicationBase property is ignored. That is, no assemblies are probed for in the directories specified by the ApplicationBase property. In addition, the values of the PrivateBinPath property and the PrivateBinPathProbe property are ignored. No assemblies are probed for in the directories specified by the PrivateBinPath property.

The DisallowApplicationBaseProbing property provides an additional layer of control over the loading process. In the normal assembly loading sequence, the application base is probed before the AppDomain.AssemblyResolve event is raised. However, some applications might need to load assemblies from an OLE compound file within a document, or from a unique known location that is neither in the global assembly cache nor in the directories specified by the ApplicationBase and PrivateBinPath properties. Such applications can use the DisallowApplicationBaseProbing property to avoid the delay caused by normal probing, and to avoid loading copies of the necessary assembly that might be located in the normal probing paths.
