While developing Softphone application using VS 2008, I moved a project from one computer to a different one. When I then tried to rebuild the solution I received the following error:

“Unable to find manifest signing certificate in the certificate store”

As I was sure that I wasn’t using any certificate to sign the assembly I couldn’t understand the reason for this error message. It turned out that I had to manually go into the *.vbproj file and remove the following four lines that were apparently left over from some past experiments with signing using a certificate:

After I had removed those lines I reloaded the project and the solution rebuilt just fine.
