Hello, This morning I found the LightSpeed designer to crash Visual Studio 2010 frequently (almost on every save). I can't provide you with the solution. Is there anything else I can do to give you the information so you can see why it happens. I upgraded to the nighly build 4.0.811.18502 yesterday. Werner PS If you provided the means to obfuscate a model such that it doesn't have actual names and properties in it, then I may be able to share it. For example, just rename each entity to Entity1, Entity2 etc and each property to Property1, Property2 etc. In any association rename it to association1. This way our IP is not shared (on a forum such as this) and you may be able to reproduce issues much faster. |

Does this happen with new models or only on your existing model? Which version were you on before the upgrade? (This will help us home in on when the bug was introduced.) Does the problem go away when you revert to the previous build? Do you have custom templates in play? We don't have a way of obfuscating a model, but if you're willing to share it with us, you can email it directly to support@mindscape.co.nz. We will treat it as confidential. If you can't even share it with us, then you'll need to obfuscate it manually. |

The previous version was 4.0.734.18278. The Lightspeed designer has always crashed intermittently. Its just doing so very often now. There are no custom NVelocity templates. I have a couple of T4 templates but they are not being executed. Its an existing model. I upgraded so I can implement the ability to "purge" previously deleted data. Reverting to a previous version is a tad complicated. What I am doing in essence is to manually add the existing EDMX file to an existing LSMODEL file. I tried the suggestion of dragging and dropping the EDMX file from the solution explorer into the design surface, but that does nothing. From Visual Studio Help:

Do you have any logging/tracing that I can enable and send you the file? Werner |
|
|
|
|
If you create a new model and a couple of dummy entities, does it crash on that? |
|
|
|
|
You can revert the designer while still keeping the latest version of the runtime (for the 'purge' functionality). Copy the Mindscape.LightSpeed and Mindscape.LightSpeed.Linq DLLs to a project Lib folder if you haven't done so already, and change the project to reference them at that location instead of the install location. Then uninstall LightSpeed and reinstall the older version. Your project will continue to use the runtime DLLs in the Lib directory, while the designer will be the older version. |

It does not crash on a new model. |
|

|

You should have the model in your support mailbox. Werner

If you have the Output window open before saving the model, does anything get written there? Or does VS crash so completely that you're not able to see? Are your model changes saved successfully? Is the generated code updated successfully? |
|
|
|
|
Visual Studio 2010 crashes and its not possible to see what is in the output window. Most of the times the model changes are saved succesfully. I cannot verify in those cases that the code was updated. That said, the last crash I had did not save my last changes and code was not updated. |

Thanks for the extra info. The fact that the timing is sometimes before and sometimes after suggests that there is an environmental factor, possibly involving an add-in which responds to saving changes and which LightSpeed is somehow conflicting with. If VS is sometimes crashing *before* the save, our code may not even be in play at this point, so I'm not sure we'll be able to log this. That said, I will try to add some logging around a couple of the places that we do control and we will see if that produces anything. I've just tested your model with the current nightly build of LightSpeed and I'm not able to reproduce a crash. This again points me towards a possible environmental factor. Another possibility is that the previous version of LightSpeed did not uninstall cleanly and the two versions are conflicting. Go into Control Panel and have a look in Add/Remove Programs for "Mindscape LightSpeed." If there is more than one entry there, uninstall them all, then reinstall the latest version. Finally, for more immediate diagnostics you could try attaching a debugger to your Visual Studio process just before doing the save, and turning on first-chance CLR exceptions. This *might* give you a stack trace that we can use to locate the problem. (Note that the designer does produce some legitimate first-chance exceptions -- some of the Visual Studio APIs we call don't have a 'try' variant -- which it catches internally, so the presence of first-chance exceptions doesn't necessarily indicate a smoking gun.) |
|
|
|
|
For the next nightly build I've added logging to our bits of the save code to save the exception details to %LocalAppData%\Mindscape. By the way, I just tried injecting an exception into the save process and Visual Studio caught it and displayed a "can't save" message. The fact that your VS dies hard makes me concerned that something access violationy is happening deep within the unmanaged part of VS, possibly outside the control of our code. Hopefully the logs or a debugger trace will reveal a bit more though. |
