Hi Guys,
We had a major breakthrough with an issue that had been with us from day one of the Visual WebGui designer. I guess most of you are used to reopening the designer after certain actions. You can imagine that we had sleepless nights thinking about this issue as we aim at perfection and this issue is far from being some thing you can live with.
The issue I am talking about is this issue, which as its id (642) indicates is a long standing issue that has a few related issues.
The irony of it all is that all the hours spent on finding this issue resolves in simply deleting one extra disposing call. When renaming forms, changing certain parts of the code and some more places, Visual Studio requires the designer to reload and that simulates the closing and opening the designer but obviously not perfectly as one service required to be left between the first loading and the second one.
So to make a long story short... 6.4 preview 4 will contain this fix and we will issue a 6.3.x version with this fix as well as soon as possible. This means that you will have to get used to not closing the designer every now and then... hope that works for you... :-)
Cheers,
Guy
