I've used FileZilla as my favourite FTP application for quite a while, and admire its amazing functionality.
As I'm a programmer myself, I often run into situation where I need FTP support. And then I always find myself wanting to use FileZilla as a base FTP component in my system, because it supports just about everything I need.
My problem is that I program in C#.NET, and thus can't use the FileZilla source code directly, even though it's open source. Even if it was possible to use it directly, I wouldn't know where to start when looking at the source code, since I can't even get it to compile in VS.NET (I try to compile it as C++, of course).
Would it be possible to wrap the FileZilla code in C# using P/Invoke so we would get the best free .NET FTP library in existance?
While you could wrap just about anything, controlling the interface and error conditions is going to be very challenging. I'd recommend you check for a component/library
This class is already in the .NET Framework: http://msdn.microsoft.com/en-us/library/system.net.ftpwebrequest.aspx
This open source apparently supports SFTP: http://sshnet.codeplex.com/
Or there are a few commercials ones: http://www.dart.com/ptftpnet.aspx or http://www.rebex.net/ftp.net/
or a search of stackoverflow reveals lots of .net/FTP related questions: https://stackoverflow.com/search?q=.net+FTP+library

The MSDN Library provides great documentation for .NET/C#. However, the primary delivery medium, HTML via a web browser is suboptimal. A rich native Windows client for browsing this documentation seems like a perfect opportunity to showcase WPF. Is there such a client available? Are there any alternative interfaces to the MSDN Library?
Visual Studio 2010 can download the help to your local hard drive and load it from local server (it actually does use a local server, so search etc. works). Everything is seamless - you browse the documentation directly in VS itself. Hitting F1 with caret on a symbol will direct the searches into this local browser.
The help is to some extent integrated into the VS editor itself (for example as parameter info). ReSharper goes slightly further and displays even more info:
You can also browse the .Net code with some documentation bits in Object Browser.
Other than these, I don't know about anything - but I also don't know what features you would like. I personally think the old documentation browser present in VS <=2008 was horrible.
There are some features I would like to see which are currently not available anywhere as far as I know (for example list of implementors of an interface), but the solutions I listed are mostly all I personally need.

There has been a lot of discussion on SO about using blobs vs. files to store binaries, but the current issue I'm facing involves virus scanning. There are likely a lot of APIs that can be used to scan files saved to a file system. Are there any for blobs? Are there APIs that can be given streams or byte[]s and told to scan them for viruses and malware? If so, does anybody have any recommendations? Or is this yet another reason to steer clear of blobs?
FYI - I'm using C# and MongoDb right now for my blobs.
I was in need of a solution that the question was asking about. I evaluated a lot of things and came to the conclusion that there was really not one good .NET library for this. So I made my own.
The library is called nClam, and it connects to a ClamAV server. It is open-source (Apache License 2.0) library which has a very simple API. You can obtain it here: https://github.com/tekmaven/nClam. There is also a nuget package: nClam. I also have some instructions on how to set up the ClamAV server on my blog, here: http://architectryan.com/2011/05/19/nclam-a-dotnet-library-to-virus-scan/.
I don't know if APIs exist for scanning in-memory data (I haven't found any), but you can always put your binary data into a temporary file, scan the file (by calling an external program working in command line) and delete it when it's done.
Certainly Sophos's API (SAVI) can scan arbitrary memory buffers - you can provide call-backs for accessing the data, so it can be any data you can access.

Can anyone indicate a good 3270 emulator (which can login, scrape screen, find text, send keys etc. in background) for .NET (win and web). Something very similar to http://www.zephyrcorp.com/legacy-integration/index.htm (apparently zephyr costs like $5k per year, which is quite a lot, for one PC).
I also tried http://open3270.codeplex.com/SourceControl/list/changesets but it's way old and buggy.
Attachmate Reflection is really good, it meets all the requirements you mentioned and it has a great .NET API you can use to easily automate it from your .NET code. They don't list prices on their website but I think it is under $300...
For Desktop: I liked the idea of using a stable and well known client and remote control this instance. Therefore I ended up using x3270 (http://x3270.bgp.nu/) as the full featured, mature client in combination with X3270.Rest (https://www.nuget.org/packages/X3270.Rest/) that let's you remote control it from within a .NET application via the exposed REST interface (http://x3270.bgp.nu/rest.html). Reimplementing a complete new .NET client was not really an option because of all the alternatives out there. All those pitfalls on the road that lead to an reinvented wheel... But with an appropriate interface like the one mentioned it was quite easy to automate tasks without using DDE/HLLAPI.
If running in the background means without visible window one could start the x3270 client from .NET via Process.Start with suitable arguments to avoid a window beeing created.

There are some WebDAV clients available for Delphi (for example included in Indy 10). Is there also a simple WebDAV server solution written with Delphi?
If there is none yet, maybe you know an implementation in a different language (C#, Java) which you can recommend as a starting point for a WebDAV server implementation? (It does not have to be a full-featured solution, a rather simple skeleton could be even more helpful.)
Start your search on Google for Delphi WebDAV or Delphi WebDAV Component
That will give you some starting points: there indeed are components that can help you out.
--jeroen
As far as I know, WebDav extends HTTP functionality. You should try extending some HTTP server code. I believe synapse would be good point to start, as the code is very clear (also I personally don't like Indy ;) )
You might look at Jackrabbit, it has a WebDAV interface available (Java solution).
May be Go implementation can be taken as a start point.

I've been working on a really large project for almost 2 years and the client requirements keep changing. These changes, of course, effect everything and I would like to find a way to work with the CSS in a more dynamic fashion.
I assume I could get one of the ruby or python CSS DSLs running under ironRuby/Python but this client is very very particular about what software/frameworks are installed.
I have not found a CSS DSL where the base programming language is vb or c#.
reference:
http://sandbox.pocoo.org/clevercss/ and http://nubyonrails.com/articles/dynamic-css
Less CSS for .NET was recently released.
http://www.dotlesscss.org/
I am not sure about any publicly available products, but I have written an ASP.NET HttpHandler for .css files a few times. Its a pretty simple task, and I usually add things like variable and basic expression support, realtime minification, comment stripping, etc. Is this what your looking for? If so, I think each time its taken maybe 10 hours of work max to write, debug, and implement the handler...not too bad given all the benefits.
You could also write your own DSL, using either the DSL Toolkit that's part of the Visual Studio SDK, or using Oslo. In the former case, the result could be .css files plus whatever else you needed, including API code for your ASP.NET application to call upon.
