Compiler Error C2441
'variable' : a symbol declared with __declspec(process) must be const in /clr:pure mode
By default, variables are per application domain under /clr:pure. A variable marked __declspec(process) under /clr:pure is prone to errors if modified in one application domain and read in another.
Therefore, the compiler enforces per process variables be const under /clr:pure, making them read only in all application domains.
For more information, see process and /clr (Common Language Runtime Compilation).
Example
The following sample generates C2441.
// C2441.cpp
// compile with: /clr:pure /c
__declspec(process) int i; // C2441
__declspec(process) const int j = 0; // OK
