<rewrite>
  <rules>
            <remove name="RewriteUserFriendlyURL1" />
            <remove name="RedirectUserFriendlyURL1" />
            <rule name="RedirectUserFriendlyURL2" stopProcessing="true">
                <match url="^www\.myserver\.com/(.*)\.aspx$" />
                <conditions>
                    <add input="{REQUEST_METHOD}" pattern="^POST$" negate="true" />
                </conditions>
                <action type="Redirect" url="www.myserver.com/{R:1}" appendQueryString="false" />
            </rule>
            <rule name="RewriteUserFriendlyURL2" stopProcessing="true">
                <match url="^www\.myserver\.com/(.*)$" />
                <conditions>
                    <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                    <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                </conditions>
                <action type="Rewrite" url="www.myserver.com/{R:1}.aspx" />
            </rule>
        </rules>
        <outboundRules>
            <remove name="OutboundRewriteUserFriendlyURL1" />
            <rule name="OutboundRewriteUserFriendlyURL2" preCondition="ResponseIsHtml1">
                <match filterByTags="A, Form, Img" pattern="^(.*)www\.myserver\.com/(.*)\.aspx$" />
                <action type="Rewrite" value="www.myserver.com/{R:1}" />
            </rule>
        </outboundRules>
</rewrite>

this will do it - I have generated this vis IIS on my local machine - change myserver.com to your own URL. you can change the regex to actually take care of the x.aspx part of the url then it should work across all pages

First you need to remove the .aspx (default.aspx) and redirect to default to change the browser address then add the .aspx and rewire to page using IIS

<rewrite>
    <rules>
        <clear />
        <rule name="Redirect to clean URL" enabled="true" stopProcessing="true">
            <match url="^([a-z0-9/]+).aspx$" ignoreCase="true" />
            <conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
            <action type="Redirect" url="{R:1}" />
        </rule>
        <rule name="RewriteASPX" enabled="true">
            <match url="(.*)" />
            <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
            </conditions>
            <action type="Rewrite" url="{R:1}.aspx" />
        </rule>
    </rules>
</rewrite>

These are the standard rewrite rules I start every project with. I use only clean URLs for all the pages (example first rule works for www.example.com/about and second rule www.example.com/product/123)

<rewrite>
<rules>
  <rule name="Rewrite default to aspx" stopProcessing="true">
    <match url="^$" ignoreCase="false" />
    <action type="Rewrite" url="default.aspx" />
  </rule>
  <rule name="Rewrite page to aspx" stopProcessing="true">
    <match url="^([a-z0-9/]+)$" ignoreCase="false" />
    <action type="Rewrite" url="{R:1}.aspx" />
  </rule> 
</rules>
</rewrite>

Pages where I need to parse out the ID (this case number only) and add it to the query string I add a similar rule to the front:

<rule name="Rewrite Product ID" stopProcessing="true">
  <match url="^product/([0-9]+)$" ignoreCase="false"/>
  <action type="Rewrite" url="product.aspx?id={R:1}"/>
</rule>

If you want to use lower and upper case letters in the URL, set ignoreCase="true"

Edit to answer your second question plus a bonus

This rule will redirect aspx page to the clean URL:

<rule name="Redirect to clean URL" stopProcessing="true">
  <match url="^([a-z0-9/]+).aspx$" ignoreCase="true"/>
  <action type="Redirect" url="{R:1}"/>
</rule>

Replace url="{R:1}" with url="{ToLower:{R:1}}" to change URL to lowercase. See below why you would want to do this.

Also a good idea to update the Form action so that post backs don't return back to the ugly URL. Using IIS 7.5 or newer this should work:

 if (!String.IsNullOrEmpty(Request.RawUrl))
        form1.Action = Request.RawUrl;

or for IIS 7:

 if (!String.IsNullOrEmpty(Context.Request.ServerVariables["HTTP_X_ORIGINAL_URL"]))
        form1.Action = Context.Request.ServerVariables["HTTP_X_ORIGINAL_URL"];

One more thing to keep in mind... it's a good idea to keep all URLs lower case. Mixing lower/upper case characters in the URL creates duplicate content issues for SEO/Google. For example website.com/About and website.com/about will load the same page, but Google will index them as two separate pages.
