Question

我发现这个NuGet软件包很有趣：基于C＃的嵌入式rdf数据库，基于OpenLink Virtuoso，并具有MIT许可...

但是，当我尝试找到有关用法或API参考的任何说明时，我找不到它...

我从NuGet安装了TinyVirtuoso.win v 7.2.1 ...

“ First Steps”中的示例代码为什么不起作用？

它无法识别VirtuosoConnection()或IStore

using Semiodesk.TinyVirtuoso;
using Semiodesk.VirtuosoInstrumentation;

// Create a new Virtuoso store in a directory named 'Data', located in your app folder.
var virtuoso = new TinyVirtuoso("Data");

// You can have multiple separate database instances which contain different data.
// This will create a directory "Data/ExampleProject" in your app directory.
var instance = virtuoso.GetOrCreateInstance("ExampleProject");

// Start the embedded database server instance.
instance.Start();

// a) You can access the store using the Semiodesk Trinity graph database API.
// Please refer to our Trinity documentation and examples for more information.
IStore store = StoreFactory.CreateStore(instance.GetTrinityConnectionString());

// b) Alternatively, you can use it with plain ADO.Net to use the relational
// database features and SQL (make sure to install OpenLink.Data.Virtuoso).
var connection = new VirtuosoConnection();
connection.ConnectionString = instance.GetAdoNetConnectionString();
connection.Connect();

// When you are done, stop the embedded database server instance.
instance.Stop();

快速查看一下，我认为TinyVirtuoso并不是“ C＃中的嵌入式RDF数据库”（这并不奇怪，因为这将需要移植整个基于C的VOS（Virtuoso开源）项目）。请注意，their wiki says —

TinyVirtuoso不会以任何方式链接到OpenLink Virtuoso。它只是提供了一种启动，停止和配置软件的方法。

Elsewhere in that wiki，他们说他们依赖Open Source Virtuoso project，但是尚不清楚他们是否完全安装了Virtuoso，只是安装了ADO.NET客户端库，还是介于两者之间。

我确实注意到了this advice-

该软件受Semiodesk支持。如果您有任何疑问，建议或想告诉我们您在使用哪个项目的库，请不要犹豫到hello@semiodesk.com。

-导致我在somewhat more informative (and I think more recently updated) page上遇到了Semiodesk's website，这表明他们确实打算捆绑主要的Virtuoso二进制文件，除其他外，我认为您尚未安装

Documentation of Virtuoso本身和its ADO.NET Provider（Installation/Configuration和Programming/API）都可以在OpenLink网站上找到。

我希望这会有所帮助...

TinyVirtuoso：文档在哪里？
