I have not seen an updated competencies list that contains 10264A and 10262A, but if previous rules are still applicable, you will find the following:
a) Teaching a development course typically requires an MCPD, so your MCTS on Framework 4.0 will not be enough.
b) You are allowed to teach a course on a new version of a product if you have the certification for the previous version, during 3 months (I think) after the exams for the new version become available. This means that your MCPD:EAD on 3.5
should let you teach 10264 and 10262, as long all the new exams have not yet been available for 3 months. But you would need to check the dates, I don't remember how long these exams have been available.
Of course, all of the preceding is my own speculation based on old rules; there is no guarantee that those rules still hold for the new courses. If you can't find an updated competencies document, you can examine your Transcript to see if you are allowed
to teach those courses. However, this is not 100% accurate, since sometimes the latest courses fail to find their way into the Transcript until some time after they are released.
If it is any help, I do have the MCPD on 3.5 and the MCTS:Web on 4.0, just like yourself, and 10264 does NOT appear in the "Courses certified to teach" on my transcript. On the other hand, I have the MCPD:Win on 4.0, and 10262 DOES appear on my
Transcript.
