Could Not Load File Or Assembly Powershell
or assembly up vote 40 down vote favorite 9 Has anyone ever had the issue where trying to "View Designer" on a windows form in Visual Studio .NET causes the error: "Could not load file or assembly…" ? In this case, the assembly in question was XYZ.dll. I managed to fix this by adding XYZ.dll and all its references to my project's references (even though my could not load file or assembly visual studio project doesn't directly depend on them) and rebuilding the whole solution. However, after that, I removed all those references from my project, rebuilt, and it still worked. One other piece of information is that I use Resharper 2.5. Someone else pointed out that it might be Resharper doing some shadow copying. I'll look into this next time this happens. Does anyone have a understanding of why this error happens in the first place, and possibly the 'correct' way to fix it? visual-studio windows-forms-designer share|improve this question edited Nov 5 '13 at 10:39 Irshad 2,29251534 asked Oct 3 '08 at 13:19 Chien Chern Khor This would probably depend a whole lot on what XYZ.dll actually was... Was it part of the .NET runtime? Was it a custom DLL? Was it some other part of your solution? –Matthew Scharley Oct 3 '08 at 13:27 Chen, do you mean that your project uses classes from XYZ.dll but doesn't reference it? –Ivan Nikitin Oct 21 '11 at 20:15 add a comment| 18 Answers 18 active oldest votes up vote 23 down vote We have same problem.

misbehaving designer in Visual Studio 2010 Published by marco on Updated by marco on Anyone who’s used Visual Studio 2010[1] for a non-trivial Windows Forms https://www.earthli.com/news/view_article.php?id=2487 project has run into situations wherein the designer can no longer be opened. Usually, it’s because the class encounters null-reference exceptions when referencing data that is unavailable until runtime. Those are easy to fix: just avoid referencing that data in the constructor or load-routine while in design-mode. However, sometimes Visual Studio has problems could not loading assemblies that it seems it should have available. Sometimes Visual Studio seems to have a devil of a time loading assemblies whose location it has quite explicitly been told. If you like, there is a walkthrough—with screenshots!—at the end of this article, which shows how to solve even the most intractable designer problems. could not load A Tale of Two PlatformsOne of the troubles is that many developers have moved to 64-bit Windows in order to take advantage of the higher RAM limits. The move to 64-bit causes some issues with many .NET assemblies in that the developer (i.e. probably YOU) didn’t remember to take into account that an assembly might be loaded by x86 code or x64 code or some combination thereof. The designer will sometimes be unable to load an assembly because it has been compiled in a way that cannot be loaded by the runtime currently being used by the designer as explicitly requested in the project settings. That said, the request is explicit as far as Visual Studio is concerned, but implicit as far as the developer is concerned. The only long-lasting solution is to learn how assemblies are loaded and what the best compile settings are for different assemblies so that you will run into as few problems as p
