How does "com4:ManagedInProcessServer" work under a MSIX packaging scenario?
I'm trying to create a MSIX package for a classic Windows desktop app. The app is written in C# (.NET Framework 4.7.2), and it's running perfectly both before and after packaging. The problem is that the app exposes a COM class library (also written in C#) for interop with other apps. The original installer of this app registers the COM library with "regasm.exe". Given that MSIX have the ability to expose COM servers, namely with the "windows.comServer" extension, I've tried adding the following extension to package manifest, but it does not work as intended: <com:Extension Category="windows.comServer"> <com:ComServer> <com:SurrogateServer DisplayName="TheApp Class Library"> <com:Class Id="8ae249dd-05f8-403e-ac32-00feab49c1f5" Path="TheApp.Library.dll" ThreadingModel="STA" /> </com:SurrogateServer> </com:ComServer> </com:Extension> After some research I've found that C# COM libraries registers differently with normal ones; namely it requires a few more entries than DLL path and CLSID written into the registry. Digging through the documents, I've found that https://learn.microsoft.com/en-us/uwp/schemas/appxpackage/uapmanifestschema/element-com4-managedinprocessserver seems to be just what I needed. So I've tried to use the following extension instead: <com4:Extension Category="windows.comServer"> <com4:ComServer> <com4:ManagedInProcessServer Assembly="TheApp.Library, Version=1.0.0.0, Culture=neutral" RuntimeVersion="v4.0.30319"> <com4:Class Id="8ae249dd-05f8-403e-ac32-00feab49c1f5" ImplementationClass="TheApp.Library.ExtensionManager" ThreadingModel="STA" Virtualization="disabled" /> </com4:ManagedInProcessServer> </com4:ComServer> </com4:Extension> But it still does not work. In fact, this time even the "HKEY_CLASSES_ROOT\CLSID\{...}" registry entries do not get generated. I've checked the https://learn.microsoft.com/en-us/windows/win32/appxpkg/troubleshooting#get-diagnostic-information and no error has ever occurred during package installation. It is as if the extension declaration is not there. What confuses me more is that "com4:ManagedInProcessServer" does not allow specifying codebase for the assembly. With "regasm.exe" one can specify the full path to COM library with "/codebase", but "com4:ManagedInProcessServer" does not seem to be allowing this. I've been looking for relevant information for quite some time, but all I could find is the single document page on XML schema (linked above), with no real-world code examples. (And by "no" I mean literally ZERO code example on Internet.) I would like to know if "com4:ManagedInProcessServer" works under the situation described above, and if not so, what should I do to have a C# COM library exposed by a MSIX package? If it matters, I'm using the latest version of Visual Studio Community 2022 with SDK version 10.0.22621.0. The MSIX package is to be deployed on a Windows 11 23H2 system.
MicrosoftTeams cmdlets not working with AccessToken
I am trying to run cmdlets from powershell module MicrosoftTeams (version 2.0.0) in a C# web application. I am using Authorization code flow and code from the answer provided in this post to acquire token: https://stackoverflow.com/questions/43488511/acquire-aad-token-using-asp-net-web-forms. Note: I had changed resource in the code to graph.windows.net to acquire AAD token. Token is acquired by using AuthenticationContext.AcquireTokenByAuthorizationCodeAsync method. Once the token is acquired, I run the following lines to create a powershell instance in C# and to import MicrosoftTeams Module. PowerShell pshell InitialSessionState iss; iss = InitialSessionState.CreateDefault2(); iss.ImportPSModule(new[] { "MicrosoftTeams" }); pshell = PowerShell.Create(iss); Then to connect with MicrosoftTeams, I run the following code: var connectCmd = new Command("Connect-MicrosoftTeams"); connectCmd.Parameters.Add("AadAccessToken", AccessToken); connectCmd.Parameters.Add("AccountId", "xxxxxxx@xxxxxx.onmicrosoft.com"); pshell.Commands.AddCommand(connectCmd); var result1 = pshell.Invoke(); Code works fine till here. After this I clear the shell commands and invoke the Get-CsTeamsCallingPolicy cmdlet: pshell.Commands.Clear(); pshell.Streams.Error.Clear(); pshell.AddScript("Get-CsTeamsCallingPolicy"); var result2 = pshell.Invoke(); After Invoke, I get an exception and this dialog pops up: Pressing 'Continue' brings back the same dialogue a couple of times. Exception details from this screen are: System.Collections.Generic.KeyNotFoundException was unhandled by user code HResult=-2146232969 Message=The given key was not present in the dictionary.

Trying to run this logic from the powershell editor shows similar behavior: Running the following two lines: $AccessToken = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' Connect-MicrosoftTeams -AadAccessToken $AccessToken -AccountId 'xxxxxxx@xxxxxx.onmicrosoft.com' gives this result: Account Environment Tenant TenantId ------- ----------- ------ -------- xxxxxxx@xxxxxx.onmicrosoft.com AzureCloud xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx I then run Get-Team cmdlet: Get-Team -User xxxxxxx@xxxxxxx.onmicrosoft.com which results in this message: Get-Team : The given key was not present in the dictionary.

All the above code works fine if connecting to AzureAD module via Connect-AzureAD cmdlet like this both in web application and powershell editor: Connect-AzureAD -AadAccessToken $AccessToken -AccountId 'xxxxxxx@xxxxxxx.onmicrosoft.com' If someone has faced and successfully resolved this issue or have some tips on how to resolve this, please help. I have already tried a lot of things including searching for the specific exception messages and any possible solutions but found nothing that could help in this particular scenario, installed the latest version of MSTeams module, the previous version was old and did not have all the cmdlets that I am looking to work with. I installed the preview version of MSTeams module also to see if this issue is fixed in the upcoming release. Uninstalled the deprecated SkypeForBuisnessOnline Connector module, updated windows and so on. If you look at https://docs.microsoft.com/en-us/powershell/module/teams/connect-microsoftteams?view=teams-ps#example-4, this is what I am trying to achieve.Creating an addin for sharepoint that uses c#
Hi Everyone, I would like tp create an addin for Sharepoint online which uses c# code and libraries. I am following the tutorial mentioned in: https://docs.microsoft.com/en-us/sharepoint/dev/sp-add-ins/get-started-creating-sharepoint-hosted-sharepoint-add-ins I have deployed the addin created from default template in Visual Studio 2019, and now I wish to include and execute a C# file for generating an access token from this framework. I am confused how to call this file from .aspx page and make it work on the sharepoint addin page. Please help.
