CIL Generator Error (CILG0002): The size of the data area '... . ...' is not valid.
The CIL Generator has detected an invalid data area declaration in (the binary assembly of) a referenced C# library.
The term "data area" designates the available controller memory areas (system/shared/user memory).
For example, a shared memory area is defined in the managed library code. The definition of this data area is invalid, e.g., because the start address is greater than the end address.
Remedy
Contact the provider of the library.
If the library source code is available and can be edited, correct the data area declaration and release the library again.
