您可以从 64 位进程创建 32 位 AppDomain 吗？

Question

Is it possible to create an AppDomain to host/run some 32-bit code from a 64-bit process, and then be able to pass/marshal data from the newly created AppDomain to host AppDomain?

I could do this as an out-of-process executable, but I am trying to avoid having a large binary foot-print for the 32-bit process (which happens to be a stand-alone .NET 6.0 console executable).

Answer 1

You can't half on the same process to run as 64 bit and the other as 32 bit. So even if .Net 6 would support creating AppDomains ( which it does not ) creating 32bit AppDomain in 64bit process would not work.

You need to create separate processes for that which may share most of the code /binaries - you only need bootstraping app to be explicitly 32 or 64 bits, the rest of your assemblies can be "Any".
