I have a project in which I'd like to use some of the .NET 4.0 features but a core requirement is that I can use the System.Data.SQLite framework which is compiled against 2.X. I see mention of this being possible such as the accepted answer here but I don't see how to actually achieve this.

I think I'm leaning toward C# and .net as a concentration language for learning web development. I would like to learn good programming fundamentals and I've looked at pretty much everything else. The four I've narrowed it down to have been C#, Python, Ruby and PHP. Is there a reason to stay away from C# (and I don't think the cost issue would really apply to my solo-developer situation but I could be totally wrong). Any thoughts? I realize that these are all great languages so I'm not trying to ask which is the best overall. However, would Ruby be a viable alternative for a first language or does it have too much "magic under the hood" coupled with Rails, and unorthodox methodologies? I do like what I've seen with the language. Source: Tips4all

I'm new to .Net and I'm trying to understand the basics first. What is the difference between MSIL and Java bytecode?

Unlike Java, why C# treats methods as non-virtual functions by default? Is it more likely to be a performance issue rather than other possible outcomes? I remind reading a paragraph from Anders Hejlsberg about the several advantages the existing architecture is bringing out. But, what about side effects? Is it really a good trade-off to have non-virtual methods by default?

We Want to Run Our C# Code on the JVM My company has a large C# code base. Well over half of this code is our core engine for creating, reading, modifying, calculating and writing Excel workbooks. We frequently get questions from customers and potential customers asking whether we are going to build a Java version of our engine - many of them are not at all interested in the UI. We even have a few customers who have taken the trouble to use our .NET library from their Java applications. So, we would like to build a Java version of our core engine, ideally without maintaining a separate Java source code base. Eric Sink described this problem very well. I am in a similar position except for the fact that our software license includes royalty free deployment, making Eric's choice of Mainsoft a nonstarter for us. I have been Googling the likes of "c# to jvm" every few months for several years now with no joy. Having spent ~7 years developing similar software for J
