Use recommended dispose pattern to ensure that object created by 'RSA.Create()' is disposed on all paths. If possible, wrap the creation within a 'using' statement or a 'using' declaration. Otherwise, use a try-finally pattern, with a dedicated local variable declared before the try region and an unconditional Dispose invocation on non-null value in the 'finally' region, say 'x?.Dispose()'. If the object is explicitly disposed within the try region or the dispose ownership is transfered to another object or method, assign 'null' to the local variable just after such an operation to prevent double dispose in 'finally'.
