I have downloaded the newest available VisualGDB version (build 3327) and the new “Preparing for build” counter is behaving strangely. When I startup the project the counter starts to increase and never stops (see attached screenshot).
Thanks for letting us know. Looks like some solution-related events come in the order not expected by VisualGDB. Please let us know if you open the project via file File menu in Visual Studio, or by clicking on the .sln file in Explorer. Please also let us know whether there are other projects in the same solution and what is the type of the project (Embedded, Linux, Arduino, etc.).
