C#:Unable to find manifest signing certificate in the certificate store

 C#工程從VS2005升級 到2008後，編譯時報以下錯誤：
    "Unable to find manifest signing certificate in the certificate store"

解決方法：

    手工打開 *.csproj ，刪除下面四句：

    <manifestcertificatethumbprint>...</manifestcertificatethumbprint> 
    <manifestkeyfile>...</manifestkeyfile> 
    <generatemanifests>...</generatemanifests> 
    <signmanifests>...</signmanifests> 

刪除後就可以正常編譯了。
