  #308202

  have a SSRS report that uses a custom library. The custom library returns a string values, and I have tested this with a windows application.

  In the SSRS report. I have set the expression value for a text box as =CodeReportingLibrary.CodeReportingFunctions.GetImage(1232)

  However, when i preview the report the text box value shows as #ERROR. I checked the error list and I get a warning message : Warning 1 [rsRuntimeErrorInExpression] The Value expression for the textrun ‘Textbox5.Paragraphs[0].TextRuns[0]’ contains an error: Attempt by security transparent method 'CodeReportingLibrary.CodeReportingFunctions.GetReferenceImage(Int32)' to access security critical method 'Microsoft.TeamFoundation.Client.TfsTeamProjectCollection..ctor(System.Uri)' failed. Assembly 'CodeReportingLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is partially trusted, which causes the CLR to make it entirely security transparent regardless of any transparency annotations in the assembly itself. In order to access security critical code, this assembly must be fully trusted.

  I have updated the rssrvpolicy.config in ReportServer folder, to include my custom dll.

  <CodeGroup

  class="UnionCodeGroup"

  version="1"

  PermissionSetName="FullTrust"

  Name="CoDeMagSample"

  Description="CoDe Magazine Sample. ">

  <IMembershipCondition

  class="UrlMembershipCondition"

  version="1"

  Url="C:\Program Files\Microsoft SQL Server\MSRS10_50.R2\Reporting Services\ReportServer\bin\CodeReportingLibrary.dll"

  />

  Can some one help me to understand why I am getting this error?
