Reporting Services with framework 4

Question

Hi,

I created a new project with framework 4, loading a custom assembly to populate certain fields of a report. The report was added using the method:

this.rpViewer.LocalReport.AddTrustedCodeModuleInCurrentAppDomain("tstDat, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null");

This threw this exception related to enable the CAS policy. I found the trick adding the following node in app.config:

<runtime>
    <NetFx40_LegacySecurityPolicy enabled="true"/>
</runtime>

And it worked fine.

Now, the problem is that I have this other project originally created with framework 3. I was recently required to upgrade it to framework 4. This project has also custom assemblies to populate report data.

I also use AddTrustedCodeModuleInCurrentAppDomain to load the assembly so I added the NetFx40_LegacySecurityPolicy node to app.config but it keeps throwing the exception I've mentioned before.

I added also the node <loadFromRemoteSources enabled="true" /> with the same result...

I'm lost on that. It seems the problem is only in the upgraded project. Does anyone know how to solve it?

I can't use the default framework 4 sandboxing because I need the custom assembly static property to populate some data from the report viewer container form and  sandboxing keeps this data in a different domain, so the exception is not thrown but the property is empty.

Thanks.
