How am I supposed to use the license with my ef core

Post by Skippermix » Fri 20 Sep 2019 12:19

I am trying to use a licensed version
I have a Full framework 461 solution where I have one repository class library that is setup with the new SDK Csproj style but with <TargetFramework>net461</TargetFramework>

I am then trying to add the license key attribute to our connectionstring for our user license@vfl.dk

So it looks something like

User Id=xxx;Password=xxxx;Server=xxx;Sid=xxx;Direct=True;Persist Security Info=True;License Key=*long key*

I have installed <PackageReference Include="Devart.Data.Oracle.EFCore" Version="9.7.734" />

But when I run it I get “Unknown connection string parameter 'License Key'”

How am I supposed to use this correctly?

Currently this aspnet web api solution already have an old integration to Oracle with the old EF and the wierd thing is that when I deploy my current solution without the License Key' in the connectionstring it works even though I havent installed the devart trial driver on those machines, but those machines, can it just use the same license as those drivers?

The current implementation of dotConnect for Oracle includes two sets of assemblies for EF Core:

1) the .NET Framework Devart.* assemblies which are shipped with installation:
* assemblies are created in C:\Program Files (x86)\Devart\dotConnect\Oracle\ , GAC 2.0 (C:\Windows\assembly\GAC_MSIL\), GAC 4.0 (C:\Windows\Microsoft.NET\assembly\GAC_MSIL\)
* licensing approach is described at https://www.devart.com/dotconnect/oracl ... nsing.html

2) the .NET Standard (.NET Core) Devart.* assemblies which are available via NuGet:
* you can download packages from https://www.nuget.org/packages/devart.d ... cle.efcore
* licensing approach is described at https://www.devart.com/dotconnect/oracl ... ndard.html
<TargetFramework>net461</TargetFramework>

[...]

when I run it I get “Unknown connection string parameter 'License Key'”
With Target framework=.NET Framework, the first location CLR looks for the assembly is GAC. So, your development environment works with .NET Framework Devart.* assemblies (shipped with installation) instead of .NET Standard Devart.* assemblies (downloaded from NuGet).

A solution is to reinstall dotConnect for Oracle in your development environment and select the "Do not install assemblies in the GAC" option in Setup Wizard.
