title: MSBuild Using Wrong Version of Assembly to Compile RDLC File
body: <p>I am using the reportviewer control from VS 2010 to create client side reports (rdlc).  Everything is working fine on my development machine, and when I manually compile (via VS2010) and manually deploy to a test machine that doesn't have development tools installed.</p>
  
  <p>In order to get the test machine to work (without installing VS2010 or ReportViewer.exe), I had to add references in my project to Microsoft.ReportViewer.Winforms, Microsoft.ReportViewer.Common and Microsoft.ReportViewer.ProcessingModel and have them all "Copy Local".</p>
  
  <p>I have the rdlc files configured for Build Action => embedded resources.  This is the default setting when adding a new rdlc to the project.  I am open to configuring this otherwise if this would resolve this problem (no idea if its related).</p>
  
  <p>The problem: since adding the rdlc files, the solution no longer builds on the build server.  I have installed ReportViewer.exe on the build server, and have verified that the required assemblies exist in the GAC.  The .Net 4 framework is NOT installed on the build server--I don't think this is required because the solution targets the 3.5 runtime.</p>
  
  <p>I believe the root of the problem is the following from the build log:</p>
  
  <blockquote>
    <p>Target "RunRdlCompiler": Building
    target "RunRdlCompiler" completely.
    Output file
    "obj\Release\RdlCompile.compiled" does
    not exist. Using "RdlCompile" task
    from assembly
    "Microsoft.ReportViewer.Common,
    Version=9.0.0.0, Culture=neutral,
    PublicKeyToken=b03f5f7f11d50a3a". Task
    "RdlCompile":
    Report\RDLC\GreenReport.rdlc (0,0): 
    error rsInvalidReportDefinition: The
    report definition is not valid.
    Details: The report definition has an
    invalid target namespace
    '<a href="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition" rel="noreferrer">http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition</a>'
    which cannot be upgraded.</p>
  </blockquote>
  
  <p>From what I can tell, Microsoft.ReportViewer.Common version 10.0.0.0 is what should be used to "compile" the rdlc, but MSBuild appears to be using 9.0.0.0.  I believe if I could force it to use the right version (which IS installed in the GAC), the solution would compile.</p>
