Question

We have a Windows Service app written in C# targeted for AnyCPU. It runs on a Win2003 (32bit) server. Recently it started to run out of memory.

What is involved in redeploying this service to a Win2003 (64bit) box. Do I need to recompile it and will the App get more memory if I do not recompile it?

Was it helpful?

Solution

Nothing special if the exe is set for AnyCPU- the 64-bit CLR will load by default on a 64-bit machine. You just have to make sure you're REALLY AnyCPU ready (no unsafe OR safe 32-bit pointer math assumptions, etc). If you're running all managed code with no PInvokes, you should be in good shape.
