Why won't my ASP MVC Views build the second time round

Question

I have enabled MvcBuildViews in my project.

It works completely fine when I build.

Then if I build again/change something and try to build again, it fails when it starts to compile the views with the error:

CS0103 The name 'model' does not exist in the current context It is pointing at the first cshtml file in obj\Release\AspnetCompileMerge\Source\bin\Views\Shared\EditorTemplates\DateRange.cshtml

Here's that file, not that it helps:

@model MyProject.Web.Extensions.DateRange
@using Abp.Web.Mvc.Extensions

<div class="input-daterange input-group">
<input type="text" class="input-sm form-control" name="startDate" id="startDate" required="required" />
<span class="input-group-addon">～</span>
<input type="text" class="input-sm form-control" name="endDate" id="endDate" required="required"/>

I absolutely have no idea why this is happening. The only way to get this working is to delete my obj folder and rebuild.

I want it to be smart and know what it does and doesn't need to rebuild (since it takes ages).

Here is my views/Web.Config:

Answer 1

So, the ACTUAL problem was in my project file I had this:

<Target Name="MvcBuildViews" AfterTargets="AfterBuild" Condition="'$(MvcBuildViews)'=='true'">
    <AspNetCompiler VirtualPath="temp" PhysicalPath="$(WebProjectOutputDir)" />
  </Target>

Deleted it, and I could recompile no problem.

Answer 2

Have you tried to relocate the obj folder outside from your solution? Maybe it helps.

Unload your asp.net mvc project in the solution explorer and edit the project file.

Look for BaseIntermediateOutputPath and IntermediateOutputPath entries in the csproj files, and modify them:

<BaseIntermediateOutputPath>D:\Temp\VS\Your project name\obj\</BaseIntermediateOutputPath>
<IntermediateOutputPath>$(BaseIntermediateOutputPath)$(Configuration)\</IntermediateOutputPath>
