Issue creating asymmetric key
<p>I am trying to run the code below but continuously get the error "The certificate, asymmetric key, or private key file is not valid or does not exist; or you do not have permissions for it."</p>

<p>I have tried changing file permissions, running as an administrator (this is on a local database), restarting the SQL service and my computer but nothing is fixing it.</p>

<pre><code>CREATE ASYMMETRIC KEY [DatabaseName_UserDefinedFunctions]
AUTHORIZATION [dbo]
FROM EXECUTABLE FILE = 'C:\Users\username\Source\Project\Database\DatabaseProject\bin\Output\ProjectName.Database.SiteDb.dll';
</code></pre>
