Version control in Developer tab

Question

When I open the SF (2020.1 with GUI 2020.2.10) there's a button called “Version control” in the Developer tab page. I do notice some warnings. What does the tab page do and should I be worried things not working properly? I'd assume all should be green or blue. Some assemblies are referring other (patch)versions and some assemblies cannot be loaded it seems.

Hello René,

The version checker’s primary purpose is to signal the potential of issues resulting from deployment errors. It used to be the case that people manually deployed a Windows GUI somewhere by overwriting an existing directory, leaving outdated dependencies behind, which could lead to unexpected behavior. Fortunately, this rarely ever happens anymore.

Then there’s the .NET dependency resolver which prefers DLL’s in the Global Assembly Cache over those deployed together with the GUI itself, if their versions are similar enough. If memory serves me right, an example of when this goes wrong is when AutoCAD is installed on a system, which shares its DevExpress dependencies with the GUI, but uses a different version.

Other than that, the version checker doesn’t contain a lot of knowledge and so it gives some false positives. Some indirect dependencies such as the Infragistics4.Win.UltraWinCalcManager.v18.1.FormulaBuilder DLL are never actually needed, and so we don’t add it to the GUI download.

Another thing to keep in mind is that DLL’s are loaded lazily, i.e. as late as possible. This means that if you run the version checker before opening a screen, it shows messages about some expected dependencies not being loaded yet, which means it cannot check their versions. So if it warns about e.g. a scheduler DLL, open a screen with a scheduler on it, and the message either disappears or turns into an actual warning about a version mismatch.

Now, when I look at your screenshot, it seems to indicate that two different versions of the DevExpress DLL’s are loaded. This is indeed unusual, and even though the version difference is small, there’s potential for regressions. i would definitely want to know where those 19.1.4 DLL’s are and why they’re being referred to rather than the 19.1.6 versions which have also been loaded. I’d recommend to use software such as WinMerge to perform a difference analysis between the deployed GUI and a clean download from the Thinkwise Customer Portal.

The origin of the files was from the GAC I think. The origin of the 19.1.4 file is probably from ApexSQL, because when I de-installed it, the dll file also disappeared from the GAC (C:\Windows\Microsoft.NET\assembly\GAC_MSIL\DevExpress.Utils.v19.1\v4.0_19.1.4.0__b88d1754d700e49a) and thereby also the wrong reference in “Version control”.

This means that if you run the version checker before opening a screen, it shows messages about some expected dependencies not being loaded yet, which means it cannot check their versions. So if it warns about e.g. a scheduler DLL, open a screen with a scheduler on it, and the message either disappears or turns into an actual warning about a version mismatch.

Now, when I look at your screenshot, it seems to indicate that two different versions of the DevExpress DLL’s are loaded. This is indeed unusual, and even though the version difference is small, there’s potential for regressions. i would definitely want to know where those 19.1.4 DLL’s are and why they’re being referred to rather than the 19.1.6 versions which have also been loaded. I’d recommend to use software such as WinMerge to perform a difference analysis between the deployed GUI and a clean download from the Thinkwise Customer Portal.

The origin of the files was from the GAC I think. The origin of the 19.1.4 file is probably from ApexSQL, because when I de-installed it, the dll file also disappeared from the GAC (C:\Windows\Microsoft.NET\assembly\GAC_MSIL\DevExpress.Utils.v19.1\v4.0_19.1.4.0__b88d1754d700e49a) and thereby also the wrong reference in “Version control”.
