我正在使用MSBuild任务构建我的VS2010解决方案,并遇到了奇怪的问题,其中包括Web Site项目。如果我在Visual Studio 2010中打开该解决方案并尝试编译它,则可以正常工作。但是,如果我尝试从我的MSBuild脚本进行编译,则会出现错误。
我已经追踪到问题所在,即WebSite目录中有一个用户控件,该控件不使用代码后台。
重现步骤:
1. 想象一下你有一个简单的解决方案。只有一个网站和两个用户控件:
web\Controls\HelpButton.ascx:
我看起来好像是如果编译用户控件的顺序错误,“HelpButton”被放置在“TestUserControl”上,并且“TestUserControl”为“HelpButton”对象的属性赋值。
这是已知问题吗?有什么建议可以解决这个问题?
一个没有对我起作用的解决方法是从MSBuild脚本中执行devenv.exe并让devenv.exe构建解决方案。它成功地编译了,但问题是我不能通过这种方式发送其他MSBuild属性。
谢谢

重现步骤:
1. 想象一下你有一个简单的解决方案。只有一个网站和两个用户控件:
web\Controls\HelpButton.ascx:
<%@ Control Language="C#" ClassName="HelpButton" %>
<script runat="server">
private string _helpUrl;
public string HelpUrl
{
get { return _helpUrl; }
set { _helpUrl = value; }
}
</script>
web\AnotherFolder\TestUserControl.ascx:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="TestUserControl.ascx.cs" Inherits="AnotherFolder_TestUserControl" %>
<%@ Register Src="~/Controls/HelpButton.ascx" TagPrefix="myCtrl" TagName="HelpButton" %>
<myCtrl:HelpButton runat="server" ID="HelpButton" />
web\AnotherFolder\TestUserControl.ascx.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class AnotherFolder_TestUserControl : System.Web.UI.UserControl
{
protected override void OnLoad(EventArgs e)
{
this.HelpButton.HelpUrl = "trada";
base.OnLoad(e);
}
}
使用VS2010可以轻松构建此网站。
2.) 使用以下MSBuild:
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"
DefaultTargets="Build">
<PropertyGroup>
<SolutionProperties>Configuration=Release</SolutionProperties>
</PropertyGroup>
<Target Name="Build" DependsOnTargets="">
<MSBuild Projects="BuildTest.sln" Targets="Build" Properties="$(SolutionProperties)" RebaseOutputs="true">
</MSBuild>
</Target>
</Project>
3.) 运行MSBuild脚本: msbuild build.msbuild
出现以下错误信息:
