"Common Language Runtime detected an invalid program." error

Hi All,

I encounter the following problem when using ANTS Performance Profiler 7.4 Professional.

I'm trying to profile a console application, developped using .NET 3.5. and VS2008.
The profiled application failed with an error :
Common Language Runtime detected an invalid program.

This application works fine when launched either standalone or under debugger.

Profiling works also if the debugging session is launched with options :
- Sample method-level timings.
- Method-level timings; only methods with source
- Method-level timings; all methods

But fails with the options :
- Line-level and method-level timings; only methods with source
- Line-level and method-level timings; all methods

Any help ?

Regards,
SGayet

    Hi, and sorry you're seeing performance issues.

    This shouldn't have got obviously slower since version 4. The call-tree can be a little slow due to the nature of the 3rd party control it uses but this hasn't changed since v4. Are you comparing performance like-for-like in relation to the profiling mode? If you're using line-level in v8 and method level or sampling in v4, then it may explain it.
    If you can also indicate the vague specs of the machine so we can get some sort of comparison of the time taken to select a section of timeline and get the update between the two versions it would be great.
    Feel free to email support@red-gate.com if you'd rather!
