NetFx40_LegacySecurityPolicy in design-time mode

Is there any way to make legacy design-time code execute with NetFx40_LegacySecurityPo开发者_StackOverflow中文版licy switched on?

More specificaly, is there any way to make DevExpress 8.2 winforms designer work in VisualStudio 2010?

I got errors due to this issue and found no help about design-time mode, just about run-time:

<runtime>
  <NetFx40_LegacySecurityPolicy enabled="true"/>
</runtime>

How should I fix problems with winforms designer?

Just add this

<NetFx40_LegacySecurityPolicy enabled="true"/>

into your VS2010 DevEnv configuration file, you'll find it in C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe.config

There is a <runtime> section, just copy it at the first place.
I've had the same problem with DevExpress 8.2

If some people face the same problem while developing ASP.Net apps, they should add the Attribute to the Cassini config file placed in C:\Program Files (x86)\Common Files\microsoft shared\DevServer\10.0\WebDev.WebServer40.exe.config
