Exception with crystal reports

Question

I am developing application which uses SAP Crystal Reports for reporting with Visual Studio 2013 Professional. I downloaded and install package from SAP site, install that. Report is prepared using wizard (this works correctly). Problem is if I following step in source code:

myCrystalReport.SetDataSource(myDataSet);

myDataSet is filled with required data. Displayed error is:

An unhandled exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll

Additional information: Could not load file or assembly 'file:///C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet1\crdb_adoplus.dll' or one of its dependencies.

During installation folder dotnet1 were not created. There is only folder dotnet. Do somebody know how can be this problem resolved?

Thank you.

Answer 1

I had the exact same problem. My solution was to add this xml to the app.config file inside the <configuration> level:

<startup useLegacyV2RuntimeActivationPolicy="true">
   <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>

Answer 2

<configuration>
<startup useLegacyV2RuntimeActivationPolicy="true">
</startup>
</configuration>

Due to mixed mode assemblies has changed this problem will occur so it is recommended to you use above code into app.config file.

Answer 3

you have use below code in app.config and also have to set .net profile 4 client to .net profile 4 or 4.5 in project property.

<startup useLegacyV2RuntimeActivationPolicy="true">
  <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
