Specifies that your managed application process should have a single copy of a particular global variable, static member variable, or static local variable shared across all application domains in the process. This is primarily intended to be used when compiling with /clr:pure, because under /clr:pure global and static variables are per application ___domain, by default. When compiling with /clr, global and static variables are per process by default (do not need to use __declspec(process).
Only a global variable, a static member variable, or a static local variable of native type can be marked with __declspec(process).
When compiling with /clr:pure, variables marked as per process must also be declared as const. This ensures that per process variables are not changed in one application ___domain, and giving unexpected results in another application ___domain. The primary intended use of __declspec(process) is to enable compile time initialization of a global variable, static member variable, or static local variable under /clr:pure.
processis only valid when compiling with /clr or /clr:pure and is not valid when compiling with /clr:safe.
If you want each application ___domain to have its own copy of a global variable, use appdomain.
