Answer 1

I have never used IKVM myself but I do know people that used it successfully.

Anyway, have you tried the following options:

• Use jacob : you can expose your java classes as COM objects that can be consumed by NET code.

• Use jni4net

One thing you could try:

1. Expose the Java as a Jax-Ws web service .

2. Use .NET's svcutil.exe against it to generate ac# client

3. Use the c# client to call Sum
