VisualStudio.com can't load the temporary UWP certificate during builds

Question

I set up my Visual Studio Team Service account to clone my private GitHub repo and build the Windows UWP application anytime I queue a build. The cloning works without any issue

Answer 1

By default .gitignore ignores any *.pfx file. Therefore it is not added to git. I had the same issue, that the build machine does not has the *_StoreKey.pfx file and therefore the build did not succeed.

For me the solution was to install the *_StoreKey.pfx on the build server. Then building the solution on the build server succeeds.
