可以说，我有一个旧的应用程序，它会试图加载外部组件。

在旧的应用程序被编译为CLR 2。 新的组件编译为CLR 4。

我希望能够运行老应用程序内部CLR 4。我记得有一些的 XML清单魔术的参与。

我怎样才能创建清单xml文件告诉oldapplication.exe应在CLR 4运行？

我发现了一些建议，但他们似乎并没有为我工作。

oldapplication.exe.config：

 ＆LT; XML版本=1.0＆GT？;
＆lt;结构＆GT;
 ＆LT;启动＆GT;
      ＆LT;！ - 设置相应的.NET版本 - ＆GT;
      ＆LT; requiredRuntime版本=4.0.0.0/＆GT;
 ＆LT; /启动＆GT;
＆LT; /结构＆gt;
 

同时给予再出手，我发现这个文件，以作为我的模板：

  

C：\ WINDOWS \ Microsoft.NET \框架\ v4.0.20506 \ Aspnet_regsql.exe.config

 ＆LT; XML版本=1.0＆GT？;
＆lt;结构＆GT;
    ＆LT;启动＆GT;
        ＆LT; supportedRuntime版本=v4.0.20506/＆GT;
        ＆LT; requiredRuntime版本=v4.0.20506安全模式=真/＆GT;
    ＆LT; /启动＆GT;
＆LT; /结构＆gt;
 

我还更新了code至报告当前CLR：

  Console.WriteLine（typeof运算（对象）.Assembly.ImageRuntimeVersion）;
 

它的工作原理吧！

解决方案

您需要提供正确的版本号。请注意，这是公测版本1，它会改变，直到RTM落户之一：

 ＆lt;结构＆GT;
 ＆LT;启动＆GT;
      ＆LT; supportRuntime版本=4.0.20506/＆GT;
 ＆LT; /启动＆GT;
＆LT; /结构＆gt;
 

Lets say I have an old application which will try to load an external assembly.

The old application is compiled to CLR 2. The new assembly is compiled to CLR 4.

I would like to be able to run that old application inside CLR 4. I remember there was some xml manifest magic involved.

How can I create that manifest xml file to tell that oldapplication.exe shall run under CLR 4?

I found some suggestions, but they do not seem to work for me.

oldapplication.exe.config:

<?xml version ="1.0"?>
<configuration>
 <startup>
      <!--set the appropriate .net version-->
      <requiredRuntime version="4.0.0.0"/>
 </startup>
</configuration>

While giving another shot i found this file to serve as my template:

C:\Windows\Microsoft.NET\Framework\v4.0.20506\Aspnet_regsql.exe.config

<?xml version ="1.0"?>
<configuration>
    <startup>
        <supportedRuntime version="v4.0.20506"/>
        <requiredRuntime version="v4.0.20506" safemode="true"/>
    </startup>
</configuration>

I also updated the code to report current CLR:

Console.WriteLine(typeof(object).Assembly.ImageRuntimeVersion);

It works now!

解决方案

You need to give the proper version number. Note that this is the beta 1 version, it will change until RTM settles one:

<configuration>
 <startup>
      <supportRuntime version="4.0.20506"/>
 </startup>
</configuration>
