Nunit2.6.2调试.net4类库

调试类库的时候，发现不能调试断点故障的解决：

1、在Nunit的安装目录下，打开nunit.exe.config，文件内容如下：

 <?xml version="1.0" encoding="utf-8"?>

<configuration>

<!--

   The GUI only runs under .NET 2.0 or higher. The

   useLegacyV2RuntimeActivationPolicy setting only

   applies under .NET 4.0 and permits use of mixed 

   mode assemblies, which would otherwise not load 

   correctly.

  -->

<startup useLegacyV2RuntimeActivationPolicy="true">

<!-- Comment out the next line to force use of .NET 4.0 -->

</startup>

<runtime>

<!-- Ensure that test exceptions don't crash NUnit -->

<legacyUnhandledExceptionPolicy enabled="1"/>

<!-- Run partial trust V2 assemblies in full trust under .NET 4.0 -->

<loadFromRemoteSources enabled="true"/>

<!-- Look for addins in the addins directory for now -->

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

<probing privatePath="lib;addins"/>

</assemblyBinding>

</runtime>

</configuration>

2、在<startup>段中加入：

<requiredRuntime version="v4.0.30319" />
