The name of the resource '<string>' cannot be used as a valid identifier
You did not specify a resource name that can be converted to a valid identifier when strongly typed code generation is turned on for the resource file. For example, a name including "%" would cause this error.
The first <string> is the resource name that you specified.
The second <string> is the invalid character or characters found.
To correct this error
Rename the resource by using a valid identifier and try importing again.
