I have a project which can be compiled perfectly into vs2012 without ANY warning/error.

When I try to compile the same project using msbuild 3.5 or 3.0 I get this errors:

Is fully necessary for me to compile this project using msbuild, I need to avoid that errors.

Possible solution 1?: A switch or something else in msbuild.exe to ommit the critical errors?

Possible solution 2?: If someone can help making the necessary modifications to my class (I don't know how to do it by myself):

This is the GlobalHotkeys class where all are the suppossed errors... (Like I said the project can be compiled using the VS IDE without any error or warning):

框架目标版本和语言版本之间存在差异。听起来您正在使用新的语言功能，并以 .NET 3.0 或 3.5 为目标；这很好，但您需要使用能够理解这些语言特性的编译器。

基本上，使用 MSBuild 4（或任何当前版本）。您仍然可以使用它来定位 .NET 3.0。或者，将自己限制在较旧的语言功能上。Visual Studio 中有一个对话框，用于选择项目应该让您使用的语言版本（或者至少对于 C# 项目有）：

在此处输入图像描述

注意：我不知道 VB 是否提供了类似的选项来帮助您将自己限制为特定的语言版本。

具体来说，我怀疑这里的语言特性是“自动实现的属性” ——如果你坚持使用较旧的编译器，你将不得不使用长手语法。
