Pasting bad code over bad code crashes VS

[Victor Hurdugaci]

1. Create a new web application (no authentication)

2. Open the Home/Index view and paste this code (ignore any compilation errors):

   @using BuildDashboard.Server.Models.Dashboard
   @using SectionLayout = BuildDashboard.Server.Models.Dashboard.Layout
   
   @model SectionTile
   
   @{
   const int MinGridItemSize = 2;
   const int GridSpaces = 12;
   const int MaxItemsPerRow = GridSpaces / MinGridItemSize;
   }
   
   <div class="page-header">
   <h1>@Model.Title</h1>
   </div>
   
   @*@if (Model.Layout == SectionLayout.Normal)
   {
   foreach (var tile in Model.Tiles)
   {
       @await Component.InvokeAsync("Tile", new { tile })
   }
   }
   else
   {
   var itemsPerRow =
           }*@
   

3. Save

4. Copy the code below

   @using BuildDashboard.Server.Models.Dashboard
   
   @model SectionTile
   
   @{
   const int GridSize = 12;
   
   var actualItemsPerRow = Model.ItemsPerRow;
   if (actualItemsPerRow < 1)
   {
       actualItemsPerRow = 1;
   }
   else if (actualItemsPerRow > 12)
   {
       actualItemsPerRow = 12;
   }
   
   while (GridSize % actualItemsPerRow != 0)
   {
       --actualItemsPerRow;
   }
   }
   
   <div class="page-header">
   <h1>@Model.Title</h1>
   </div>
   
   <div>@actualItemsPerRow</div>
   
   <!--@*@if (Model.Layout == SectionLayout.Normal)
   {
   foreach (var tile in Model.Tiles)
   {
       @await Component.InvokeAsync("Tile", new { tile })
   }
   }
   else
   {
   var itemsPerRow =
           }*@-->
   

5. Go back to the view

6. Select all

7. Paste

Result: VS crashes

@victorhurdugaci - can you get dmp file?

[Victor Hurdugaci]

Sure, if you tell me how to do it :)

Note: This probably should be moved to the aspnet/Tooling repo.

@victorhurdugaci can you move to https://github.com/aspnet/Tooling/issues/ and close this?
