Why does my non-dynamic class method return dynamic

The following code results in the C# compiler returning a dynamic type, but that class and the GetUserProfileAsync method are normal, 'concrete' code.

var profile = await this.UserProfileRepository.GetUserProfileAsync(this.ViewModel[ViewModelKeys.UserGivenName]);

Intellisense on the profile variable is absent, instead the editor/compiler says:

This operation will be resolved at runtime.

What's going on?

Check the type of the parameter being passed into the GetUserProfileAsync method, its probably dynamic.

The compiler cannot thus know the type and resolve the method/callsite on the UserProfileRepository class.

To fix the issue, cast the value coming from this.ViewModel to the type you expect.

var profile = await this.UserProfileRepository.GetUserProfileAsync((string)this.ViewModel[ViewModelKeys.UserGivenName]);

Now the compiler can work it all out.
