C# process to read a java process' outputstream without using sockets or IDL/CORBA or file or database or JNI

I need to add a service to my web application which opens a java process from command line and communicates through input/output streams of that jvm thread instead of using IDL or sockets or database or files. Is there such connection between processes, which is very close to pure java?

C# webserver opens helloworld.jar and writes 1M bytes to console of it(console.in), then waits for console.out. I've read that command line arguments cannot go beyond kilobytes level. Maybe streams can go megabytes if there is such communication?

Communicating with only strings would be ok but using objects themselves would be better.

In this answer I demonstrate the way to IPC using stdin/out between executiable-jar(STW application) and a Winform application.

The answer was linked into a solution I made.

To read and write into the application you use the methods: WriteLine and OutputDataReceived (a Process methods, see this class).

In the Java process you use Scanner to read and Println to write.(this is the java class)

The communication is through strings. You can serialize your objects into json and then pass them.(Using Json.net and Gson)
