英文:
Gremlin.net.dll not found
问题
在从Gremlin.net 3.6.1升级到3.6.2时，我遇到了一个文件未找到异常，指向"rootOfProject"/Gremlin.net.dll。这发生在我的startup.cs中，当实例化GremlinClient时。
我已经尝试将Gremlin.net.dll复制到项目的根文件夹。然后它可以正常工作。
我发现代码突然在根目录而不是\bin文件夹中寻找.dll文件，这很奇怪。
英文:
when moving from Gremlin.net 3.6.1, to 3.6.2 I get a FileNotFound Exception pointing to "rootOfProject"/Gremlin.net.dll
This is happening in my startup.cs when instantiating the GremlinClient
services.AddSingleton<GremlinClient>(s =>
{
GremlinServer server = new GremlinServer(hostname: "host", port: 443, enableSsl: true, username: $"collection", password: "password"]);
var connectionPoolSettings = new ConnectionPoolSettings
{
MaxInProcessPerConnection = 32,
PoolSize = 4,
ReconnectionAttempts = 4,
ReconnectionBaseDelay = TimeSpan.FromSeconds(1)
};
var socket = new Action<ClientWebSocketOptions>(o =>
{
o.KeepAliveInterval = TimeSpan.FromSeconds(10);
});
return new GremlinClient(server, new GraphSON2MessageSerializer(), connectionPoolSettings, socket);
I have tried to copy the Gremlin.net.dll to the root folder of the project. And then it works.
I find it strange that the code is suddenly looking for the .dll at the root and not in the \bin folder

If you really need the functionality of 3.6.2 release, one way would be to add copy command inside .csproj file. This is a temporary solution while you wait for the next Gremlin version.
This issue only seems to happen for local environment, so could write something like this:
<Target Name="CopyDependencies" AfterTargets="Build">
<Copy Condition="$(ASPNETCORE_ENVIRONMENT) == 'local'" SourceFiles="$(OutDir)Gremlin.Net.dll" DestinationFolder="$(ProjectDir)" SkipUnchangedFiles="false" />
</Target>
Note that you need to add the environment variable ASPNETCORE_ENVIRONMENT: local as well. The value you decide yourself, either it's local, development etc.
After that is done, add Gremlin.Net.dll file to the .gitignore, so that it is not tracked via source control.
