Designer file not updating visual studio
For instance, when I installed 2012 next to 2010, all my DB designers started failing (much as you describe).
The two versions used a pair of dlls of differant versions stored in the same location.
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.
However, sometimes Visual Studio has problems loading assemblies that it seems it should have available.
The next time you save the XSD file you should be able to see the dataset file, dataset.(or .vb) file, for your XSD.
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].
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.There is a predefined list of custom tools available in the product; this property enables you to see which custom tool is applied to a file.
