I am using RTC 3 and have some files with .xaml extensions. These are just text files but the change set explorer (viewed via the web interface in browser) does not show a diff for these files. It gives this reason:

Differences between the Before and After states of the file cannot be computed
because neither of the content types of the states can be displayed: application/unknown, application/unknown

Works just fine for other files, .cs for example.

Any help greatly appreciated,

James

Hi, when you say you're using RTC VS Client, you're using that to check in files as well right? You mention a Web Client as well, so I'm wondering.
Could you look at the Visual Studio Properties View for the xaml file and check the MIME Type and Line Delimiter properties, under the Jazz Source Control section?
I'm a part of the VS Client development team and we use WPF extensively and have a whole lot of xaml files. I just checked the MIME Type and Line Delimiter properties for these files, which were set automatically for us when we checked in.
Line Delimiter None(Binary)
MIME Type application(unknown)
And the files compare just fine from within the VS Client. I tried it just now to reconfirm. Did you try from within the VS Client as well?

Yes we're using the visual studio client to do check-ins. When I say the web interface I mean the main set of RTC web pages.

Anyway, your suggestion on setting the MIME type worked : )

If I change Properties > File Properties :
MIME Type to text/plain
Line Delimiter to Platform

Then the diff view starts working!

Excellent, although obviously a default setting would be good. I'll dig around in VS and see if I can find anything. I didn't even know about the MIME type setting until now though so thanks for pointing me at that.

Thanks again for the help

However, the reason you provide for why you would like to have it is reasonable at least to me. So you might want to consider to add an enhancement request so that we get it logged. Maybe there is a way to make it easier to support your use case.

You could multi-select the files in the Solution Explorer and choose the Jazz Properties menu option. That brings up a single Jazz properties dialog where you can change the MIME type of multiple files.
The Jazz Properties dialog if opened for multiple files will show only properties that are the same across all files - say maybe repository URL, component etc. If the files have different MIME types, it will display a blank for the for MIME type property value, but if you then set it to a specific value the VS Client will set it across all the files you selected.
