The project framework is .NET 4.8. I installed Azure.AI.FormRecognizer 4.1.0, which requires minimum Azure.Core 1.34.0 which requires System.Diagnostic.DiagnosticSource 6.0.1. But for some reason the FormRecognizer asks for 6.0.0.0. Am I missing something obvious?
This is the output:
Exception thrown: 'System.IO.FileNotFoundException' in Azure.AI.FormRecognizer.dll
An exception of type 'System.IO.FileNotFoundException' occurred in Azure.AI.FormRecognizer.dll but was not handled in user code
Could not load file or assembly 'System.Diagnostics.DiagnosticSource, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.
In the app.config it gets generated as
<dependentAssembly>
<assemblyIdentity name="System.Diagnostics.DiagnosticSource" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.0.0.1" newVersion="6.0.0.1" />
</dependentAssembly>
And I tried to change it to 6.0.1.0 but that didn't do anything.
This is what the error looks like during runtime:
private Uri _uri;
private AzureKeyCredential _credential;
private DocumentAnalysisClient _analysisClient;
private DocumentModelAdministrationClient _modelClient;
public AzureOcr()
{
_uri = new Uri(_diEndpoint);
_credential = new AzureKeyCredential(_diKey);
_analysisClient = new DocumentAnalysisClient(_uri, _credential); // here it throws "System.IO.FileNotFoundException: 'Could not load file or assembly 'System.Diagnostics.DiagnosticSource, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.'"
_modelClient = new DocumentModelAdministrationClient(_uri, _credential);
}
In the main class library there was an older version of DiagnosticSource 5.0.0.0, I changed that to 6.0.0.1 and it was resolved. Unfortunately very project specific.
I just added a bindingredirect of the NuGet Package in the main class library's app.config (without installing the package directly in the class library).
