I'm trying to create a project "Universal Windows". For this I have the Visual Studio 2015 Blank app (Universal Windows) used template.
I now get the following compilation error:
CS0731 The type forwarder for type 'Windows.Foundation.IAsyncOperation`1' in assembly 'Windows' causes a cycle
In the following source:
string filename = "SampelData.json";
var path = Windows.ApplicationModel.Package.Current.InstalledLocation;
Windows.Storage.StorageFile file = await path.GetFileAsync(filename);
string jsonResult = await Windows.Storage.FileIO.ReadTextAsync(file);
be precise, the fault displayed for await path.GetFileAsync(filename)
and await Windows.Storage.FileIO.ReadTextAsync(file).
The analysis of the error message Microsoft has not helped me: CS0731
Update
As to X of the error caused by faulty under load metadata. The type forwarder for type 'type' in assembly 'assembly' causes a cycle
This error can only occur with improperly formed imported metadata. It cannot occur with only C# source.
Do I have reset the settings of the VS2015, by deleting the chache folder content and run devenv /resetuserdata
.
Unfortunately, without success
Update 2
Still no solution, the file treatment corresponds to the Microsoft documentation, see https://msdn.microsoft.com/en-us/library/windows/apps/mt185401.aspx .
I here actually wanted to load sample data. But I have currently developed also the WebService for the provision of data. I let my sample data just about this WebService deploy. This is but I think no satisfactory solution.
麻烦已经解决了Visual Studio 2015的更新2。自安装更新以来,至少问题不再包括在内。
