XML/XSD intellisense not working in Visual Studio 2010

intellisensevisual studio 2010xmlxsd

I am working on xml and xsd files in VS 2010 but intellisense isn't working. Intellisense is working for the same files in VS 2008, however.

When I type '<xs:' options like "attribute", "complexType", "simpleType", or "element" do not appear.

Is there some difference between the VS 2008 and VS 2010 that I'm missing?

I add an xsd file to my solution. All the proper namespaces are generated automatically as such:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="XMLSchema2"
    targetNamespace="http://tempuri.org/XMLSchema2.xsd"
    elementFormDefault="qualified"
    xmlns="http://tempuri.org/XMLSchema2.xsd"
    xmlns:mstns="http://tempuri.org/XMLSchema2.xsd"
    xmlns:xs="http://www.w3.org/2001/XMLSchema">

</xs:schema>

The "xsdschema.xsd" is in the "C:\Program Files\Microsoft Visual Studio 10.0\xml\Schemas" directory.

There is a check mark in the "Use" column in the XML Schemas dialog box.

I discovered what happened. Visual Studio 2010 imported the schemas from Visual Studio 2008. This caused duplication warnings like the one below:

Warning The global attribute 'http://www.w3.org/XML/1998/namespace:lang' has already been declared. C:\Program Files\Microsoft Visual Studio 10.0\xml\Schemas\xml.xsd

In the XML Schemas dialog, I removed the old ones from the schema cache. You'll have to restart Visual Studio.

XML Validation with XSD in Visual Studio IDE

You'll need to associate the XML document in Visual Studio with the XSD file you have.

You should see something like this in your Properties window of the XML document:
In the XML schema set editor (opens when you click on the (...) ellipsis in the "Schemas" textbox in your Properties window) you need to make sure you have your schema present. Also, make sure the Use column for that schema is enabled - if not, click on it - you'll get a drop-down list of options, pick the Use one with the green checkmark:
Make sure Visual Studio's Error List windows is visible (menu View > Error List). This will show all inconsistencies between XML and XSD schema definitions.
Once all of that is in place, the Visual Studio XML editor should highlight problems with your XML in the editor using blue squigglies:

XSD – The content is not valid.

You're getting the error because xsd:restriction is not allowed as a child of xsd:element. Try adding your xsd:restriction to an xsd:simpleType and then specifying that type in your xsd:element.

You could add the xsd:simpleType directly to the xsd:element, but since you're using the same restriction 3 times, it makes more sense to put it in a simpleType outside of the elements.

Here's an example. I named the simpleType "stackOverflowTest":

<xsd:schema elementFormDefault="qualified" version="1.0" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:element name="company_donation_request" type="company_donation_requestType" />
  <xsd:complexType name="company_donation_requestType">
    <xsd:sequence>
      <xsd:element name="order" type="orderType"></xsd:element> 
      <xsd:element name="donation" type="donationType"></xsd:element>
    </xsd:sequence>
  </xsd:complexType>
  <xsd:complexType name="donationType">
    <xsd:sequence>
      <xsd:element name="campaign_key" type="stackOverflowTest" minOccurs="1" maxOccurs="1"/>
      <xsd:element name="amount" type="xsd:decimal" minOccurs="1" maxOccurs="1"/>
    </xsd:sequence>
  </xsd:complexType>
  <xsd:complexType name="orderType">
    <xsd:sequence>
      <xsd:element name="id" type="stackOverflowTest" minOccurs="1" maxOccurs="1"/>      
      <xsd:element name="fulfillment_date" type="stackOverflowTest" minOccurs="1" maxOccurs="1"/>      
    </xsd:sequence>
  </xsd:complexType>
  <xsd:simpleType name="stackOverflowTest">
    <xsd:restriction base="xsd:string">
      <xsd:minLength value="2"/>
      <xsd:maxLength value="255"/>
    </xsd:restriction>  
  </xsd:simpleType>
</xsd:schema>

Hope this helps.
