Symptoms
Consider the following scenario:
-
You create a multi-project solution on a computer that has Microsoft Visual Studio 2010 Service Pack 1 (SP1) installed.
-
You open the Test View or Test List Editor tab, and then you run a unit test.
-
You try to start an application of the solution in debug mode.
Note This issue typically occurs when the solution contains a test project and a combination of the following project types:
-
Web application project
-
Silverlight project
-
Windows Communication Foundation (WCF) project
In this scenario, the Visual Studio 2010 SP1 IDE stops responding. Additionally, an error message that resembles the following is logged in the event log:
System.Runtime.InteropServices.COMException occurred
Message=Unspecified error (Exception from HRESULT: 0x80004005 (E_FAIL))
Source=""
ErrorCode=-2147467259
