的Visual Studio 2012测试项目的混合模式运行 [英] Visual Studio 2012 Test Project Mixed Mode Runtime

问题描述

我目前正在在Visual Studio 2012 RC与测试项目。我已经包括以下组件：

• Microsoft.SqlServer.Smo
• Microsoft.SqlServer.SmoExtend
• Microsoft.SqlServer.ConnectionInfo
• Microsoft.SqlServer.Management.Sdk.Sfc

这些组件是构建2.0.50727版本，我已经在.NET 4.0中的测试项目。因此，基于这一信息，我添加了一个app.config文件到项目具有以下行：

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆lt;结构＆GT;
  ＆LT;启动useLegacyV2RuntimeActivati​​onPolicy =真正的＆GT;
    ＆LT; supportedRuntime版本=V4.0/＆GT;
  ＆LT; /启动＆GT;
＆LT; /结构＆gt;
 

当我要去我收到所有的时间来运行此以下消息：

混合模式组件构建针对运行时的版本V2.0.50727'，不能在4.0运行时无需附加配置信息加载。

这是一个的Visual Studio 2012 RC测试项目，它忽略了一个虫虫危机app.config文件还是我做一些完全错误的？

有关更多的信息我已经包含了也是我的测试code：

  VAR的connectionString =新SqlConnectionStringBuilder（）
    {
        数据源= @（本地），
        IntegratedSecurity =真
    } .ConnectionString;

    VAR SQL =ALTER DATABASE [测试]集SINGLE_USER与回滚立即去;
    SQL + =DROP DATABASE [测试]去;
    SQL + =创建数据库[测试]去;
    SQL + = Properties.Resources.Test;

    VAR连接=新的SqlConnection（的connectionString）;
    VAR服务器=新服务器（新ServerConnection（连接））;

    server.ConnectionContext.ExecuteNonQuery（SQL）;
 

解决方案

这似乎是固定在Visual Studio 2012，当它来到RTM。不需要更新配置文件

我测试过，在的Visual Studio 2012更新4和Visual Studio 2013更新1 RC和你的code完美的作品与上面提到的code和汇编引用和没有更新的测试运行的配置文件。这有可能是在一个测试断裂或松开的Visual Studio 2012的候补，但如果是，它似乎已经被修正。

正如汉斯提到您可以更新的.config 文件的 vstest.executionengine.x86.exe.config ，但对于改变的您计算机上的所有的测试项目，需要应用到你的项目工作（和生成服务器上，你应该使用一个）所有的人的行为。 这应该是最后的手段!!

I'm currently working in the Visual Studio 2012 RC with a test project. I have included the following assemblies:

• Microsoft.SqlServer.Smo
• Microsoft.SqlServer.SmoExtend
• Microsoft.SqlServer.ConnectionInfo
• Microsoft.SqlServer.Management.Sdk.Sfc

These assemblies are build in version 2.0.50727 and I have a test project in .NET 4.0. So based on this information I have added an app.config file into the project with the following lines:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0"/>
  </startup>
</configuration>

When I'm going to run this I receive all the time the following message:

Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

Is this a bug in a Visual Studio 2012 RC Test Project that it ignore's the app.config file or am I doing something completely wrong?

For additional information I have included also my test code:

    var connectionString = new SqlConnectionStringBuilder()
    {
        DataSource = @"(local)",
        IntegratedSecurity = true
    }.ConnectionString;

    var sql = "alter database [Test] set single_user with rollback immediate go ";
    sql += "drop database [Test] go ";
    sql += "create database [Test] go ";
    sql += Properties.Resources.Test;

    var connection = new SqlConnection(connectionString);
    var server = new Server(new ServerConnection(connection));

    server.ConnectionContext.ExecuteNonQuery(sql);

解决方案

This seems to be fixed in Visual Studio 2012 when it went RTM. No need to update config files

I've tested that in Visual Studio 2012 Update 4 and Visual Studio 2013 Update 1 RC and your code works flawlessly with the above mentioned code and assembly references and without updating the config file of the test runner. It is possible this was broken in a beta or release candidate of Visual Studio 2012, but if it was, it seems to be fixed now.

As Hans mentions you can update the .config file for the vstest.executionengine.x86.exe.config, but that changes the behavior for all test projects on your machine and needs to be applied to all people working on your project (and on a build server should you be using one). This should be a last resort!!
