If you've ever implemented a file upload or download scenario in ASP.NET, you've likely come across the situation of having to provide a MIME type based off of a file extension. IIS does this automatically when it serves files, but it seems like in ASP.NET there isn't a good way to provide this functionality. Searches on the web might point you to building your own Dictionary of MIME types or just writing a switch statement, but this felt like a hack to me and so I turned to a resident expert, Levi Broderick. It turns out in ASP.NET 4.5 we shipped a little-known new type, System.Web.MimeMapping, which has an API called GetMimeMapping(string fileName). Here is the MSDN documentation . You can pass either a file name as the method...

This is the twenty-seventh in a series of blog posts I’m doing on the VS 2010 and .NET 4 release. Today’s blog post continues on from the Debugging Tips post I did last week, and covers some useful searching and navigation tips/tricks you can take advantage of within Visual Studio. These tips were ones that my friend Scott Cate (who has blogged dozens of great VS tips and tricks here ) recently recommended to me as good tips that most developers using Visual Studio don’t seem to know about (even though most have been in the product for awhile). Hopefully this post will help you discover them if you aren’t already taking advantage of them. They are all easy to learn, and can help save you a bunch of time. Ctrl + i - Incremental...
This is the twenty-sixth in a series of blog posts I’m doing on the VS 2010 and .NET 4 release. Today’s blog post covers some useful debugging tips that you can use with Visual Studio. My friend Scott Cate (who has blogged dozens of great VS tips and tricks here ) recently highlighted these to me as good tips that most developers using Visual Studio don’t seem to know about (even though most have been in the product for awhile). Hopefully this post will help you discover them if you aren’t already taking advantage of them. They are all easy to learn, and can help save you a bunch of time.

Search engine optimization (SEO) is important for any publically facing web-site. A large % of traffic to sites now comes directly from search engines, and improving your site’s search relevancy will lead to more users visiting your site from search engine queries. This can directly or indirectly increase the money you make through your site. This blog post covers how you can use the free Microsoft URL Rewrite Extension to fix a bunch of common SEO problems that your site might have. It takes less than 15 minutes (and no code changes) to apply 4 simple URL Rewrite rules to your site, and in doing so cause search engines to drive more visitors and traffic to your site.

Scalable Vector Graphics (SVG) is W3C standard language for describing two-dimensional vector and mixed vector/raster graphics in XML. Firefox 3+, Opera 9+ and Safari 3+ support SVG rendering. Unfortunately, Internet Explorer 8 does not support SVG natively and requires a plug-in. There a plug in from Adobe (although support was discontinued this year) as well as few pulg-ins listed in Wikipedia article on SVG . SVG element is part of upcoming HTML 5 standard which allows inline SVG in HTML documents. Inline SVG is not yet fully supported in modern browsers so you probably still want to use <object> element for now. For example: < html > < head > < title > SVG test </ title > </ head > < body > <...
Below is a tip/trick I twittered via my Twitter account earlier today. A number of people seemed interested in – so I thought i'd blog it here too. HTML Navigation Bar in VS 2008 By default, when you are in HTML source-editing mode with VS 2008 and Visual Web Developer 2008 Express edition there is a set of drop-downs that are rendered immediately above the HTML text editor view: This set of drop-downs is called the "Navigation Bar", and in the VS 2008 HTML editor they allow you to navigate between functions and methods defined within the HTML. These include both JavaScript client-side functions defined inline within the .aspx/.html file, and server-side methods defined in-line within the .aspx file when in single-file...
