Hello everyone,
I am trying to automate our users for o365 and I need to connect to MsolService via powershell in my .net project. But I get following error:
System.Management.Automation.CmdletInvocationException: Could not load type 'System.IdentityModel.Tokens.JwtSecurityToken' from assembly 'System.IdentityModel.Tokens.Jwt, Version=6.15.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.
---> System.TypeLoadException: Could not load type 'System.IdentityModel.Tokens.JwtSecurityToken' from assembly 'System.IdentityModel.Tokens.Jwt, Version=6.15.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.
at Microsoft.Online.Administration.Automation.ConnectMsolService.MsolCmdletProcessRecord()
Any help is appreciated. Thank you.
Can you explain your requirement a bit more? What exactly are you trying to do? What do you mean by automate users for 0365 ?
We will use it to change passwords for users, disable/delete them. We are already using MS Graph to add users, but other operations in graph are limited, so MsolService was my solution.
Hello Yekez,
I would recommend to:
-Upgrade System.IdentityModel.Tokens.Jwt nuget package to latest version
-Upgrade Microsoft.Owin.Security.Jwt nuget package to latest version
-Install the latest preview of Microsoft.Owin package (4.0.0)
--If the reply is helpful, please Upvote and Accept as answer--
I already have the most updated version of System.IdentityModel.Tokens.Jwt.
I am also not using Owin packages at all. This API was created for MS Graph and it works. I followed official tutorial for it and havent installed any Owin packages. Do I still need them even though I dont need them?
