Application was stopped if i run it from redgate

Postby hyang » Wed Mar 20, 2013 7:19 pm

I got a problem with start application by using redgate performance profiler.

The application self works without problem

but when i start it from redgate, it always says ".... has stopped working"

I noticed that. the exception comes from line of

JsonConvert.DeserializeObject(value, type, (JsonSerializerSettings)null);

The exception is:
{"Operation could destabilize the runtime."} System.Exception {System.Security.VerificationException}

I rechecked it, it works without any problem if I didn't run redgate.
any idea why redgate will stop applicaiton for this line? and what's solution for it? thanks a lot

Thanks for your post.

We've seen this previously- it's due to some tighter security that's incompatible with line level timings.

You can get around it by changing some of the Json source:

- find JsonWriter.cs
- comment out "[assembly:System.Security.SecurityTransparent]"
- expand the "properties" folder
- comment out "[assembly:AllowPartiallyTrustedCallers]" in the #if !SILVERLIGHT region
- rebuild your solution

With those changes, it should hopefully work. You can uncomment the lines again when you release your app if you wish.
