Hi all!!

I am trying to generate a report using crystal reports.

when i build the solution it shows me error that

The type 'CrystalDecisions.Web.CrystalReportViewer' exists in both 'c:\Windows\assembly\GAC_MSIL\CrystalDecisions.Web\13.0.2000.0__692fbea5521e1304\CrystalDecisions.Web.dll' and 'c:\Windows\assembly\GAC_MSIL\CrystalDecisions.Web\10.5.3700.0__692fbea5521e1304\CrystalDecisions.Web.dll'	C:\Users\Ujjwal\Documents\Visual Studio 2010\WebSites\4.0\Crystal\Default.aspx

when i remove the reference, it shows me that:

The type 'CrystalDecisions.CrystalReports.Engine.ReportDocument' exists in both 'c:\Windows\assembly\GAC_MSIL\CrystalDecisions.CrystalReports.Engine\10.5.3700.0__692fbea5521e1304\CrystalDecisions.CrystalReports.Engine.dll' and 'c:\Windows\assembly\GAC_MSIL\CrystalDecisions.CrystalReports.Engine\13.0.2000.0__692fbea5521e1304\CrystalDecisions.CrystalReports.Engine.dll'

after that it shows me invalid report source.

I am using a code project article to make this report

It sounds like your application has references to two versions v13.0 & v10.5. You need to make sure that your application is only referencing one version of CR.

Remove one reference not needed and check Web.Config file that only one reference is present - the one which you need.
Clear your cache. Clean and then rebuild the application.

Solution 3

I was trying to change the assembly reference in web.config but it didn't worked even when i have removed all the v10.5 references which were also there for v13.

Then i only change the version in my .aspx page and it worked.. :)
