The report viewer doesn't seem to work in asp.net projects in VS 2010. You get the following error:

Microsoft Jscript runtime error: ‘Microsoft’ is undefined.

VS also breaks on the following line of javascript code:

$create(Microsoft.Reporting.WebFormsClient.ReportViewer, {"_internalViewerId":"ctl00_MainContent_ReportViewer1_ctl03","id":"ctl00_MainContent_ReportViewer1"}, null, null);

Steps to recreate problem:

• In Visual Studio 2010 beta 2 create a new asp.net project
• Drag a ScriptManager control on to default.aspx
• Drag a ReportViewer control on to default.aspx
• Build and run the project
• You then get the problem

Is this a bug or am I doing something wrong?
