app.config “Could not find schema information” after converting to Visual Studio 2010 / .Net 4.0

Question

After upgrading my project to Visual Studio 2010 and .Net 4.0, my app.config file generates these messages upon building the project:

• Could not find schema inf

Answer 1

I changed the schema from DotNetConfig to DotNetConfig35 and it took care of the issue. This is available in the properties of the app.config file.

Right clicking the app.config file in solution explorer gives the properties of the file, right clicking in the edit window of the app.config file itself gives the properties of the XML document.
