i'm trying to create a C# COM Server which is used by a Delphi App without a COM-Registration.
The process is descried on a ms blog - Registration-Free Activation of .NET-Based Components: A Walkthrough
I created the necessarily manifest files and i linked them to the assemblies.
The App Manifest:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
type="win32"
name="Vorg"
version="1.0.0.0" />
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"
publicKeyToken="6595b64144ccf1df"
language="*"
processorArchitecture="x86"/>
</dependentAssembly>
</dependency>
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Vorg.WpfClient"
version="1.0.0.0" />
</dependentAssembly>
</dependency>
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
<security>
<requestedPrivileges>
<requestedExecutionLevel
level="asInvoker"
uiAccess="false"/>
</requestedPrivileges>
</security>
</trustInfo>
</assembly>
and the assembly manifest:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity type="win32" name="Vorg.WpfClient" version="1.0.0.0" />
<clrClass
clsid="{69A72676-8EA7-3C38-BFBC-F0DFE745C329}"
progid="Vorg.WpfClient"
threadingModel="Both"
name="KundM.Vorg.WpfClient.VorgComClient">
</clrClass>
</assembly>
those are working fine (i think). sxs does not report any errors. clsid is also correct for the com-class. but when starting the app, it is crashing by an ole exception 0x8013101b.
removing the manifests and running the app results of curse in a class not found exception. having the com-class registered the app starts normal without any errors.
the exception maybe says something like "wrong framework versions".
i tried to specify the runtime in the class manifest. but that didn't solve the problem.
what causes the exception?
how can i solve that problem?
Solved.
The program Fuslogvw.exe gave me the right direction. this tool shows the loading process of assemblies.
to enable it you need to create a reg key.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion dword ForceLog=1
the report is generated there showed me this (sorry german framework):
LOG: DisplayName = vorg.wpfclient, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null
(Fully-specified)
===
LOG: Diese Bindung startet im default-Load-Kontext.
LOG: Der Assembly-Download wurde durchgeführt. Datei-Setup wird begonnen: E:\work\VOrg\bin\vorg.wpfclient.dll.

LOG: Der Assemblyname ist: Vorg.WpfClient, Version=1.0.0.0, Culture=neutral, PublicKeyToken=174d633867192b66.
WRN: Der Vergleich des Assemblynamens führte zum Konflikt: PUBLIC KEY TOKEN.
ERR: Der Assemblyverweis entsprach nicht der gefundenen Assemblydefinition.

i did not specified the public key token in the manifests. now i do! the schemafile for manifests from microsoft is wrong! it shows version and some other attributes as optional.
i also specified the runtime within the com manifest. it is also possible to specify the framework version by a app.config file.
