我想添加一個安全的Web服務的(C#)項目作爲參考,但VS自帶了以下errror:不可能添加安全Web服務爲VS2005項目的引用
Unable to cast COM ob ject of type 'System.__ComObject' to interface type 'EnvDTE.IVsExtensibility'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{3C536122-57B1-46DE-AB34-ACC524140093}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
任何人有任何想法,爲什麼這是?
