<p>I've recently installed the MVC CTP5 and VS is now crashing on me when I try to open an aspx, I get the following error in event viewer:</p>
<pre><code>.NET Runtime version 2.0.50727.3053 - Fatal Execution Engine Error (7A035E00) (80131506)
</code></pre>
<p>I was able to find <a href="http://forums.asp.net/t/1313452.aspx" rel="nofollow noreferrer">This</a> post on the asp.net forums relating to the same issue but nobody has had a working solution yet (at least not for me).</p>
<p>Just wondering if anyone else has run into this issue and what they have done to resolve it?</p>
<p>EDIT: Wanted to add that I have tried all the tips in the article and can open the markup with a code editor but was wondering an actual solution had been found to resolve this issue.. Thanks!</p>
<p>EDIT: I don't have this issue on my Vista box, seems to only occur on my XP VM.</p>

Here are a steps to work around from
the post
that work for me:
1.Open project based on CTP5
2.IN solution Explorer, enable "Show All files"
3.Open "bin" folder and delete "Microsoft.Web.Mvc.dll", "System.Web.Mvc.dll", "System.Web.Abstractions.dll", "System.Web.Routing.dll"
4.Open "References" folder, click ONCE "System.Web.Abstractions" and in Properties window change "Copy Local" to true. Repeat same with System.Web.Routing.
5.Build application (Ctrl+Shift+B)
6.Open site.master in designer. VS will not crash.
