MSBuild 不会编译我的解决方案，它失败并出现严重且荒谬的错误

Question

我有一个项目可以完美编译到 vs2012 中，没有任何警告/错误。

当我尝试使用 msbuild 3.5 或 3.0 编译同一项目时，出现以下错误：

我完全有必要使用 msbuild 编译这个项目，我需要避免这些错误。

可能的解决方案 1？：msbuild.exe 中的开关或其他东西来忽略关键错误？

可能的解决方案2？：如果有人可以帮助对我的类进行必要的修改（我不知道如何自己做）：

这是 GlobalHotkeys 类，其中所有都是假定的错误...（就像我说的，可以使用 VS IDE 编译该项目，而不会出现任何错误或警告）：

Answer 1

framework目标版本和language版本之间存在差异。听起来您正在使用新的语言功能，并且针对 .NET 3.0 或 3.5；没问题，但是您需要使用能够理解这些语言功能的编译器。

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

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，我怀疑这里的语言功能是“自动实现的属性” - 如果您坚持使用较旧的编译器，则必须使用长手语法。
