Designer file not updating visual studio
One suggestion that I read online was to delete the file on the file system and recreate a blank (.txt) file with the same name (just change the extension) and add only the namespace and partial class declarations. copy all the markup code over to this user control.design away, then copy the markup back into your application page to start refining your code to work as a sharepoint item.The main difference with VS2010 is that automatically generated file contains all initialization code for all elements in ascx, not just declaration of protected controls (like ASP. With this approach it is not needed to copy ascx files to Control Templates folder, because all web part code is now compiled into the assembly.With this approach it is easier to develop web parts for O365 sites.The most obvious choice is to select “Run Custom Tool” from the EDMX file, but that doesn’t do anything: If you F4 the corresponding T4 file you can see that the custom tool associated with the T4 file is: Text Templating File Generator So, I selected “Run Custom Tool” from the T4 context menu: And that generated the file: But I still didn’t have the Foo class in my object model: So I selected the “Run Custom Tool” on the “Conf Speakers. I will ping the product team to see if they can run the custom tool on the EDMX file when it is saved and recursively run on all the tt files associated with that EDMX parent.Context.tt” file: And that generated the correct object model: So anytime you find your EF model and/or class files out of sync with your database then you need to manually run the “Run Custom Tool” command on both the [Entities]file and the [Entities]. 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.
NET Entity Framework.aspx) is an awesome way to quickly pull data into an app. The biggest beef I have with it is that the models can get out of sync with the database and saving the EDMX file and running the “Update Model from Database…” feature doesn’t work.
One of the troubles is that many developers have moved to 64-bit Windows in order to take advantage of the higher RAM limits. 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 .
That said, the request is explicit as far as Visual Studio is concerned, but implicit as far as the developer is concerned.
However, sometimes Visual Studio has problems 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. probably YOU) didn’t remember to take into account that an assembly might be loaded by code or some combination thereof.
