title: Visual Studio 2019 Right-click Go To Definition missing for WebForms
body: <p>We have an Asp.Net 4.5 WebForms application that we still maintain. It uses WebForms with master pages. In VS 2019 the Go to Defintion option is completely missing when I select a form's button event and right-click. The same result when pressing the F12 key which should take me to the method definition for GetTokenButton_OnClick in the code behind page, nothing happens.</p>
  
  <p>This all still works nicely in VS 2017.</p>
  
  <p>Have MS dropped full support for Webforms in 2019 or am I missing an add-on or something?</p>
  
  <p>This is right-click on the button event in 2017:

  <p>This is 2019> Notice how many functions are missing:

  <p>UPDATE:
  I have the same issue with a class library that is part of the same solution. When hitting F12 on any of the class library's objects referred to in the web project's code, I get the dreaded "cannot navigate to symbol under the caret" error. What is strange is that everything builds and executes. </p>
