Add MIME mapping in web config for IIS Express

Question

I need to add a new MIME mapping for  woff file extensions to IIS Express   If I add the following snippet to the  applicationhost config  of IIS Express it works fine    lt staticContent lockAttributes  isDocFooterFileName  gt       lt mimeMap fileExtension   woff  mimeType  font x-woff    gt            But I would actually like to do add it to my  web config  so that not every developer would need to change their  applicationhost config  locally   So I removed it again from the  applicationhost config  file and added the following snippet to the project s  web config     lt system webServer gt           lt staticContent gt       lt mimeMap fileExtension   woff  mimeType  font x-woff    gt     lt  staticContent gt   lt  system webServer gt    Unfortunately it doesn t seem to work that way because when I try to access a  woff file I end up with a HTTP 404 3 error   What am I doing wrong

If anybody encounters this with errors like  Error  cannot add duplicate collection entry of type    mimeMap    with unique key attribute  and or other scripts stop working when  doing this fix  it might help to remove it first like this    lt staticContent gt     lt remove fileExtension   woff    gt     lt mimeMap fileExtension   woff  mimeType  application font-woff    gt   lt  staticContent gt    At least that solved my problem

I was having a problem getting my ASP NET 5 0 MVC 6 app to serve static binary file types or browse virtual directories   It looks like this is now done in Configure   at startup   See http   docs asp net en latest fundamentals static-files html for a quick primer

Putting it in the  web config  works fine  The problem was that I got the MIME type wrong  Instead of font x-woff or font x-font-woff it must be application font-woff    lt system webServer gt           lt staticContent gt       lt remove fileExtension   woff    gt       lt mimeMap fileExtension   woff  mimeType  application font-woff    gt     lt  staticContent gt   lt  system webServer gt    See also this answer regarding the MIME type  https   stackoverflow com a 5142316 135441  Update 4 10 2013     Spec is now a recommendation and the MIME type is officially  application font-woff

I know this is an old question   but     I was just noticing my instance of IISExpress wasn t serving woff files  so I wen t searching  Found this  and then found   http   www tomasmcguinness com 2011 07 06 adding-support-for-svg-to-iis-express   I suppose my install has support for SVG since I haven t had issue with that   But the instructions are trivially modifiable for woff    Open a console application with administrator privilages  Navigation to the IIS Express directory  This lives under Program Files or Program Files  x86  Run the command    appcmd set config  section staticContent    fileExtension  woff  mimeType  application x-woff     Solved my problem  and I didn t have to mess with some crummy config  like I had to to add support for the PUT and DELETE verbs   Yay

To solve the problem  double-click the  MIME Types  configuration option while having IIS root node selected in the left panel and click  Add     link in the Actions panel on the right  This will bring up the following dialog  Add  woff file extension and specify  application x-font-woff  as the corresponding MIME type     Follow same for woff2 with application x-font-woff2
