TFS Build / Release Configuration Utilities: Edit app.config, web.config, appsettings.json, and XML


When you’re working automated builds and automated releases, you frequently need to edit configuration files like app.config, web.config, and appsettings.json. Well, I wrote a command line utility to do this and I figured I’d share.  I’ve got a version that is an .exe that can be used on a Windows build agent and I’ve got a version that’s written with .NET Core and can run cross-platform.  Both of them have the same commands.

Here are the commands:

gets a value from <appSettings> in app.config or web.config

sets a value in <appSettings> in app.config or web.config

does a string replace in a file and replaces all occurences of a token (example: %%CONNECTIONSTRING%%) with an actual value

gets a connection string value from app.config or web.config

sets a connection string value in app.config or web.config

sets a value in a json file such as appsettings.json

locates an element in an XML file and sets an attribute value on that element

Here are the downloads:
Source code
EXE version for Windows
Cross-platform Binaries for .NET Core

I hope that these are helpful.
