title: How to use useLegacyV2RuntimeActivationPolicy with multiple projects?
body: <p>i'm trying to include handwriting recognition capabilities as a library into a WPF .NET 4 Solution containing multiple projects. Therefore i wanted to use the IAWinFX.dll (tablet PC SDK 1.7) on Win7 x64 - but when running BackgroundAnalyze i get the following error:</p>
  
  <p>"Mixed mode assembly is built against version 'v1.0.3705' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information."</p>
  
  <p>I already tried modifying the corresponding .config file (set useLegacyV2RuntimeActivationPolicy="true") as recommended here: <a href="http://social.msdn.microsoft.com/Forums/fi-FI/wpf/thread/6acf2aab-29c4-4754-95eb-cb2d717c5a2e" rel="nofollow">http://social.msdn.microsoft.com/Forums/fi-FI/wpf/thread/6acf2aab-29c4-4754-95eb-cb2d717c5a2e</a> .</p>
  
  <p>I've also set the build target to x86 and changed this on the main application as well. The main application's config also has the useLegacyV2RuntimeActivationPolicy="true" set.</p>
  
  <p>Since i'm stuck with this problem a few days already i've been looking for a solution and thus also tried disabling the "Generate serialization assembly" option as suggested here: <a href="https://support.softwarekey.com/index.php?_m=knowledgebase&amp;_a=viewarticle&amp;kbarticleid=140" rel="nofollow">https://support.softwarekey.com/index.php?_m=knowledgebase&amp;_a=viewarticle&amp;kbarticleid=140</a></p>
  
  <p>but none of those attempts gave me a working InkAnalysis... What else can i do? Is there a solutionwide .config file where i might set the useLegacyV2RuntimeActivationPolicy option? Or do i need to add this option to every project in the solution?</p>
  
  <p>Thanks in advance!</p>
