title: Missing namespace and references error in .net application
body: <p>I downloaded an application from a source control and cloned to my local folder. When I tried to build the application I get to see lot of 'missing reference' errors.</p>
  
  <blockquote>
    <p>The type or namespace name 'log4net' could not be found (are you missing a using directive or an assembly reference?) </p>
  </blockquote>
  
  <p>The log4net assembly is already added to the project but I see a warning near the assemble name</p>
  
  <p>The code has a </p>
  
  <pre><code>using Microsoft.Reporting.WebForms
  </code></pre>
  
  <p>and I get to see  </p>
  
  <blockquote>
    <p>The type or namespace name 'Reporting' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)</p>
  </blockquote>
  
  <p>What I tried:</p>
  
  <p>I want to make sure VS is building the project that's being referenced. So I set the 'Build' under the Configuration to be checked.</p>
  
  <p>I also tried changing the Target Framework from .Net Framework 4.0 to higher version. No luck!</p>
  
  <p>Any help?</p>
