Problem with .NET Framework 2.0 SDK Beta 1 x86

Hi friends,

I am C++ programmer and I'm working in Microsoft Visual Studio .NET (Microsoft Development Environment 2002).
I've removed .NET Framework 1.0 and after that I’ve installed .NET Framework Version 2.0 Redistributable Package Beta 1 (x86) and .NET Framework 2.0 SDK Beta 1 x86. Now, when I want to build solution in Managed C++, I have this error: fatal error C1108: unable to find DLL: 'alink.dll'. Description of this error is as follow: Either Mspdb60.dll or Mspdb70.dll was not in the path causing a call to LoadLibrary to fail. To resolve C1108, reinstall Visual C++ or copy the appropriate .dll file from the installation CD to somewhere in the path. I reinstalled Visual Studio and .NET Framework 1.0 is installed again. After that everything was OK, but the actual version of .NET Framework is 1.0, again. I removed .NET Framework 1.0 and I have the same error again.

What have I to do to enable my Development Environment works again?

Thanks!
