Problem building webpart using WSPBuilder

Question

I have tried creating several web parts using Visual Studio 2010 using available guides for WSPBuilder but I always get the error:

WSPBuilder Version: 1.0.9.1118 Created by Carsten Keutmann GPL License 2007 Building the solution - please wait Can not find the defined Project Assembly : c:\\documents and settings\\adm_marcus\\my documents\\visual studio 2010\\Projects\\TestWSP\\TestWSP\\GAC\\TestWSP.dll Solution compatibility: SharePoint 2007 and SharePoint 2010 Saving the Manifest.xml file Creating the WSP file Cleanup Done!

If I then deploy I can see it in the GAC using the Solutions Manager but it doesn't show as available when trying to add it to the Web Parts Gallery. I have made an IIS-reset every time after deployment.

Also, WSPBuilder doesn't create a 12-folder. Instead I get a SharepointRoot folder.

Does anyone have any clue of what the problem can be?

Answer 1

It was really quite stupid of me. I thought that I should only use the build process under the WSPBuild menu. When I used the regular menu's Build first and then WSPBuilder's Build I didn't get this message anymore. Then I got another error message regarding unmanaged code and I had to change target framework to C# 3.5.
