RSKeyMgmt no longer works in the March 2018 version(1.2.6660.39920)

The RSKeyMgmt Tool throws a .Net error... Mixed mode assembly is built against version v2.0.50727 of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.


I tried to configure you but unfortunately without success:


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


Is there a solution?

Thanks for reporting this issue! We are working on a fix.


As far as the mitigation you mentioned is concerned, make sure the structure of your RSKeyMgmt.exe.config file is valid (here is the full config file I tried on my repro environment):


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


Hope this helps,
