I am using test.cs class file in .NET solution for some common functionality in my application. I am creating test.dll file by
 > csc /t:library /r:system.dll system.data.dll test.dll
 I found the test.dll having version 0.0.0.0
Pl confirm, the generated dll file is OK or errornous.

Thanks,
Manish

Yes, it should be fine as long as the code in it is correct - I suggest testing it by using it in an application as a good way to check.
