The block of memory has no references to it and is available for allocation. Virtual memory can be in three states: State These functions allocate and free virtual memory for you on native heaps. If you're writing native code, you use Windows functions to work with the virtual address space. The garbage collector allocates and frees virtual memory for you on the managed heap. All processes on the same computer share the same physical memory and the page file, if there is one.īy default, on 32-bit computers, each process has a 2-GB user-mode virtual address space.Īs an application developer, you work only with virtual address space and never manipulate physical memory directly. The following list summarizes important CLR memory concepts.Įach process has its own, separate virtual address space. Provides memory safety by making sure that an object cannot use for itself the memory allocated for another object. Managed objects automatically get clean content to start with, so their constructors don't have to initialize every data field. Reclaims objects that are no longer being used, clears their memory, and keeps the memory available for future allocations. The garbage collector provides the following benefits:įrees developers from having to manually release memory.Īllocates objects on the managed heap efficiently. This article describes the core concepts of garbage collection. Automatic memory management can eliminate common problems, such as forgetting to free an object and causing a memory leak or attempting to access memory for an object that's already been freed.

For developers working with managed code, this means that you don't have to write code to perform memory management tasks. The garbage collector manages the allocation and release of memory for an application. In the common language runtime (CLR), the garbage collector (GC) serves as an automatic memory manager.
