MSBuild warning messages in VS2010

Question

I am getting many of the following warning messages. Is this something I should be concerned with?

Answer 1

You can ignore this warning, see this link for an explanation:

When you apply the schema attribute to your Project element, Visual Studio reads in the schema and uses the information indide to provide Intellisense during your editing. As an offshoot of this, it also warns you when it finds that you have used elements or attributes that are not part of the schema. The custom property and item elements are not part of the MSBuild schema.
