title: EntityFramework: "Parameter value is out of range."
body: <p>I have a problem with saving a decimal in EntityFramework (Model First).
  In my EDMX I declared my proprierty as a Decimal(30,10) then I tried to save the number: 
  '1215867935736100000'</p>
  
  <p>The result is:</p>
  
  <pre><code>Parameter value '1215867935736100000' is out of range.
  </code></pre>
  
  <p>I tried to make an INSERT query with SQL Server 2008 R2 Management Studio</p>
  
  <pre><code>INSERT INTO MyTable (MyColumn) VALUES (1215867935736100000)
  </code></pre>
  
  <p>and the record is saved correctly.</p>
  
  <p>Do you have any idea?</p>
  
  <p>Thanks,
  Max</p>
