来自程序集“mscorlib，版本=4.0.0.0，文化=中性，PublicKeyToken=b77a5c561934e089”的“System.Security.Principal.WindowsImpersonationContext”

Question

我想根据下面的链接从我的 asp.netcore 项目 (.net 5) 连接到我的本地表格服务器 https://docs.microsoft.com/en-us/analysis-services/tom/connect-to-existing-analysis-services-tabular-server-and-database?view=asallproducts-allversions

string ConnectionString = "DataSource=localhost";

using var server = new Server();

server.Connect(ConnectionString);

Console.WriteLine("Connection established successfully.");
Console.WriteLine();
Console.ForegroundColor = ConsoleColor.Yellow;
Console.WriteLine("Server name:\t\t{0}", server.Name);
Console.WriteLine("Server product name:\t{0}", server.ProductName);
Console.WriteLine("Server product level:\t{0}", server.ProductLevel);
Console.WriteLine("Server version:\t\t{0}", server.Version);
Console.ResetColor();
Console.WriteLine();

Console.WriteLine("Press Enter to close this console window.");

return Ok();

我在调用操作时收到此错误：

System.TypeLoadException: Could not load type System.Security.Principal.WindowsImpersonationContext from assembly mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089.

Answer 1

这是因为我使用的是这个包： https://www.nuget.org/packages/Microsoft.AnalysisServices.Tabular/ 对于 .NET 和 .NET Core，必须使用此包： https://www.nuget.org/packages/Microsoft.AnalysisServices.NetCore.retail.amd64
