Creating and debugging a Sharepoint Services 3.0 WebPart

Question

I am trying to create a WebPart for my locally installed Sharepoint Services 3.0 and I've followed various tips and guides to get it all working. However somewhere on the road I must have missed something or this is just not "in all the books".

When creating an empty Sharepoint WebPart and just hitting F5 to debug it, I get the following message:

Error 1 The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate,NTLM'. 0 0

And as this article from microsoft suggests I did enable Negotiate, NTLM. But it's still not working,

Any suggestions?

Answer 1

I solved the problem by removing Sharepoint Services 3.0 and Re-installing it using the Sharepoint Services 3.0 SP2 installation.

Which then gave me another error telling me that the URI was Null which lead me to this thread.

Conclusion

Install Visual Studio Sharepoint Tools 1.2 instead of 1.3 CTP solved everything.
