Error: A file or folder name contains an invalid character

When I was trying to deploy a ListDefinition using CTP release of VSeWSS 1.3 for Visual Studio 2008, I got the following error:
A file or folder name contains an invalid character
This message means: One or more file contains invalid character, but all my soultion files are not contain any invalid character, so after I search I found the Name of ListDefinition contains an invalid character on ListDefinition.xml file, to solve this error just remove this character
Note:     Special character are not allowed in the value of Name in the ListTemplete inside the XML File because when the user trying to deploy the solution. The system will generate a folder with this value, and you know the speacial characters are not allowed in folder or file name

ERROR: Unable to load one or more of the requested types

When I was trying to deploy a web part using CTP release of VSeWSS 1.3 for Visual Studio 2008, I got the following error:

VSeWSS Service Error: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information

The solution: I've found the following steps solving this error, here are the steps: 1. Add the All referenced assemblies to the GAC 2. Restart IIS 3. Clean the project in Visual Studio 4. Redeploy your solution again, Then everything will work.
