Here is my issue. I have about 30 programs that I maintain. All of these programs will be moving in the near future. The database connection string that they use will also be changing about 2 to 3 times in the next 6 months. I want to program to update the app.config file when the program loads so that I don't have to change all the programs everytime a server is moved. Does the make sense. Any help is appreciated.
