Question

我有以下代码：

using System;
using Microsoft.Build.Framework;
using Microsoft.Build.Utilities;

namespace MyTasks
{
    public class SimpleTask : Task
    {
            public override bool Execute()
            {
                    return true;
            }
    }
}

我有以下MSBuild脚本：

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
   <Target Name="Build">
      <MakeDir Directories= "bin"/>
      <Csc Sources="SimpleTask.cs" References="Microsoft.Build.Utilities,Microsoft.Build.Framework"      TargetType="library"
           OutputAssembly=".\bin\SimpleTask.dll" />
   </Target>
</Project>

它失败并显示以下消息：

Xbuild调用dmcs编译器，但Microsoft.Build.Utilites程序集引用了.net 2.0程序集。当我用gmcs（2.0）手工编译时，它可以工作。但我无法使用xbuild。

Answer 1

在Project xml标记中将Toolsversion设置为2.0。

Mono xbuild使用dmcs而不是gmcs
