My project solution contains all class library projects. I have used many User controls for UI. While trying to open design view, Visual studio shows error "To prevent possible data loss before loading the designer, the following errors must be resolved:

Error description: "Could not find a part of the path 'C:\Users\HP\AppData\Local\Microsoft\VisualStudio\14.0\ProjectAssemblies\4zyymhdz01\EXTCONFIG\EXConfig.xml'. "

What I have tried:

public string ReadRegistry() {
  RegistryKey rk = Registry.LocalMachine; 
  ConfigFile = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + @"\EXTCONFIG" + @"\EXConfig.xml"; 
  if (dataReaderCOnfig == null) dataReaderCOnfig = new DataReader(RConfigFile);
  return dataReaderCOnfig.GetValue("FDTXML"); 
}

The xml file is a config fie which contains path of images, templates, installation path etc. This file is kind of external configuration file for the project
Using absolute path, it works but it will work for development computer only. The output files are distributive to other PCs
