Hello Everyone,

I would like to ask you what is the best way to make a single object instance public to other processes ?  
As COM server exe is not directly foreseen is WCF still the right candidate ?

What do you think ?
Thank you very much in advance
Best regards.

Hello Sir,
Thank you for your reply but I do not see how I will be able to inter link two process via the solution you propose.

A process needs to access an object defined and instantiated in another process.

What do you think ?
 Thank you very much in advance

Actually, a process is isolated from other processes by definition. The only way to share the information is through the data transfer.

In other words, the shared information is or a persistent data structure (information from the stared database, shared file, etc.), or the active object is encapsulated in the dedicated (another) process, and you use some communication protocol to ask for the info and get the information back.

you may use named shared memory for your purpose, if the object is a data structure. either process could map to the shared memory by name. the first process would copy the shared data to the memory (with or without parameters to control access or synchronisation). either process could have a pointer to the shared instance.

if the object also is code, you could manage it in a service and provide data + functions.

Hello everyone,
thank you for all inputs but I have found the solution by googling on the web.
The solution I need to use is .NET remoting.
I can post you an example if needed.

Best regards.

The Asker told us that they found a solution by using the .NET Framework.

I don't think that any of the other comments could be called a solution or assist.
