Property value

Type: System.String
The signature of the solution.

The signature is a hash value that is generated by the sandboxed solution infrastructure when the solution is first activated. If the solution is updated to a new version, a new, different hash is automatically generated. Before running any sandboxed solution, the infrastructure checks for a changed signature. If the signature is changed, the solution is revalidated by the solution validation framework.
