Data Connections
Connecting to Windows 2000 Server Running SQL Server 2000

For the past few weeks I've been able to add database connections to my Visual Studio Data Connections and manage databases without any issues. Suddenly when I try to connect from VS 2005 or VS Express 2005 I get the following error:

Unable to Add Data Connection.
Failed to retrieve data for this request.
Could not load file or assembly 'Microsoft.VisualStudio.vspSQLEnum, Version 9.0.242.0, Culture=neutral, PublicKeyToken=8945dc8080cc91' or one of it's dependencies. Strong name validation failed.
(Exception from HRESULT: 0x8013141A)
Strong name validation failed. (Exception from HRESULT: 0x8013141A)

As far as I can remember I haven't installed anything new or changed any configurations. As I said, this problem affects both my installed instance of VS and VS Express, so I'm thinking the problem may be on the server or having something to do with network security.

Anyone know about this one?

This errors is caused by the only partial signed XXXX.dll assembly (see AssemblyInfo.cs). As a developer, you must register this assembly for verification skipping. Open the "Visual Studio .NET Command Prompt" and cd to the installation directory. Now enter e.g.:

    sn -Vr XXXX\bin\debug\XXXX.dll
    sn -Vl

I tried this solution with the following DLL:

Microsoft.visualstudio.vspsqlenum.dll

It didn't solve the problem, but maybe are other dlls that I have to register. Any ideas about how to figure out what dependencies this dll has?

Just see this link http://www.codeproject.com/dotnet/AssemblyTest.asp
