    .NET Interview Questions

    I asked this in the C# area but maybe it better belongs here:

    Interview Questions.

    I thought it would be a good learning experience for people if I ask them and see how people would answer:

    #1 How do you troubleshoot a .NET application
    #2 How many heaps will be created for a .NET application
    #3 What is involved in recompiling .NET Codes.

    1) Using a Debugger
    2) 5 per AppDomain.
    3) Using a compiler.

    In theory, there is no difference between theory and practice; in practice there is.

    Console, GUI, ASP.NET? I'd go with "the same way you'd debug a native application".

    #2 How many heaps will be created for a .NET application
    This is actually a stupid question. It depends on what GC you're using. MS.NET has 3 kinds (i believe). Desktop, Server and Concurrent. Mono has 2 kinds, Boehm and a new generational one which is in the works.

    The total amount of heaps allocated by MS.NET will be completely different to the total heaps allocated by Mono (including managed and unmanaged). Hell, .NET 3.0 could have completely changed the whole GC thing as compared to .NET 2.0, so in order to answer that question you'd also have to know which version of the framework you're talking about.

    #3 What is involved in recompiling .NET Codes.
    Recompiling? What do you mean exactly? Do you mean JITing, or do you mean the initial compilation process to create the assembly?

    Depends on how how your define the generational heap. The Microsoft convention is to consider each generation a seperate heap. So 3 managed + 1 LOH + 1 native heap. All times the number of AppDomains! [not processors], considering a process can have many app domains, there is no fixed number per process..

    That changes if you're using the server GC I edited my response above to reflect that.

    I have written a book and created an app (Android now, iPhone soon) that is from the *other* side of things -- to help developers prepare for a technical interview. You might get some ideas. It's over 200 questions with full answers and explanations.
