Deploying app.config transformation through NuGet packages

Posted on

There is a not-very-well-documented, and in my opinion limited, library from Microsoft called XML Document Transformation (XDT) that can be used to transform XML files by using XML attributes and a transformation file. The syntax reference information can be found here.

Many online articles have discussed the *.config transformation, including Custom web.config transforms and merge, Using web.config transforms with app.config files and XDT (web.config) Transforms in non-web projects. Additionally, deploying XDT in NuGet packages have also been discussed in a few articles, such as How to use XDT in NuGet – Examples and Facts, and Configuration File and Source Code Transformation. The limitations of the XDT are observed by the number of out-of-the-box verbs available to perform the transformation: Insert, […]

I don’t mean to have full blown class lectures here, but the simple action of writing and explaining things help me learn. So, that’s my reason: so that I can better understand and remember the topics that I am writing about. I also plan to use this blog myself as references for problems that I encounter and resolve. Nonetheless, I do welcome any reader and appreciate […]
