Nicolas Dorier and I have posted a new article on verifying type string names in app.config files using MSBuild.
The App.Config Type verifier is a custom MSBuild task. It examines your app.config file at compile time and verifies that string type names are resolvable.
To demonstrate, let’s take a look at a simple example. The following is an excerpt from an app.config file.
<configuration> <configSections> <section name="name1" type="Foo.BahType, Foo"/> </configSections> </configuration>
Here we have a section defined that refers to a type called BahType in assembly Foo. At compile time, the AppConfigVerifier will attempt to resolve the type BahType. If the type is unresolvable a build error will ensue.
Figure Build error from missing assembly.
We are able to control how types are resolved. In a later section we will see how we can use XML comments to exclude and include type and assembly names.
