Could you check the target .NET version of your MigrationExportService project and the version against which is compiled your Sitefinity 3.7 project. They should match - e.g. both should be 4.0. If your Sitefinity project is for .NET 4.0 then you can change the target version of your MigrationExportService to 4.0 (eventually by adding/removing a reference System.Web.ApplicationServices) and try again.
Hi Lubomir, I have done that. My 3.7 site is .NET 4.0. When I attempt to target the migrationExportService to .NET 4.0 - it errors out (See screen shot). If I take my 3.7 SF site to .NET 3.5 and take the migrationExportService to .NET 3.5, i get the errors you saw in the video from my original post. Thanks,
Please build the tool against .NET 4.0. Add a reference to System.Web.ApplicationServices.
These are not errors, these are warnings. You can safely ignore them.
