Quickstart sample code - NuGet dependencies are broken

I am new to IndentityServer and am trying to following the document to setup the Quickstart VS.Net solution on my Windows 10 desktop. After following instructions downloading and installing source code and opening up the solution in VS.Net 2017, I noticed that both NuGet dependencies - IdentityServer4 (4.0.0) and Serilog.AspNetCore (3.2.0) - are broken. Compiling the solution returns with an error: "NETSDK1045 The current .NET SDK does not support targeting .NET Core 3.1. Either target .NET Core 2.1 or lower, or use a version of the .NET SDK that supports .NET Core 3.1.". I also tried installing NuGet packages for those 2 components but it made no difference.
Could someone show me what I am missing here?
Thanks in advance!
IdentityServer4 v4.00 requires.NET Core 3.1, and because of that you need to use the latest Visual Studio 2019 and install the latest 3.1 SDKs.

Please Help me ....
NOTE: I was working on a Apache Cordova app in VS 2013. Try this it might help
I had a similar problem, but in my case it was to remove the text on the tile as it was too long for the tile. Each time I made a change to the platforms/wp8/Properties/WMAppManifest.xml it was overwritten each time when I Rebuilt the app.
I followed the below guide:
Place the custom WMAppManifest.xml file in the res/native/wp8/Properties folder. Use the generated version of the file in the platforms/wp8/Properties folder after building a Debug configuration of the project for Windows Phone 8.

AppEngine SDK 1.8.5 and Eclipse Juno not working

I've installed the Eclipse plug-in for both GWT and Appengine on 3 different machines, all with Juno (4.2). In each case, I get the following error:
"The selected App Engine SDK is not valid: Failed to initialize App Engine SDK at (path)."
Reinstalling the SDK does not make any difference. Here is more info. about the different configurations I've tried:
Ubuntu 12.0.4, Java 7, Eclipse 4.2
Mac OSX 10.8.5, Java 7, Eclipse 4.2-32 bit
Mac OSX 10.8.5, Java 7, Eclipse 4.2-64 bit
Mac OSX 10.6.8, Java 6, Eclipse 4.2-64 bit
Any suggestions for what may be going wrong and configs I could try? Thanks!
I was getting the error "Failed to initialize App Engine SDK at '..path'" in Eclipse 4.3(Kepler) with Google App Engine SDK 1.8.5 and Java SDK 1.7.0_01
When I updated the Java SDK to 1.7.0_41 (latest one) this error disappeared.
Great relief!!
I can confirm that using win7/sun jdk1.6.0_45/eclipse 4.2/gae sdk 1.8.4 the error occurred when updating to 1.8.5+ and that updating the jre that eclipse runs in to sun 1.7.0_45 solved the issue.
I can now add gae SDKs above 1.8.4.
I'm not sure why we could'nt have an error modal in eclipse to that effect.
I found my issue was that I was trying to use the app engine plugin for eclipse 4.3. I just downloaded the new eclipse and it works now. Sorry, thats the best I have..
I had the same problem and Nicky Jaidev's post helped me.
I had to update the Java Sdk to 1.7.
But also you have to update the eclipse.ini:
-vm
C:/Program Files/Java/jdk1.7.0_45/bin/javaw.exe
If you don't change this, it will keep failing.
My guess is that the AppEngine SDK version is intended for other version of Eclipse.
For Eclipse 4.2 (Juno), use this link: https://dl.google.com/eclipse/plugin/4.2
Follow the installation guide here if you unsure about how to install plugins through Eclipse directly: https://developers.google.com/eclipse/docs/install-eclipse-4.2
I had the same issue with app engine plugin for Eclipse 4.2 (well, it was the Android Developer Tools version), on Mac
OS 10.8.4.
After I saw this warning about Java 6 not being supported, https://developers.google.com/appengine/docs/java/gettingstarted/installing, I upgraded to the latest version of Java 7 and it worked.

Silverlight 4 buggy at least on Internet Explorer 9?

I have downloaded this twitter source code
http://www.silverlightshow.net/items/Silvester-A-Silverlight-Twitter-Widget.aspx
After opening in VS 2010 and setting the web project as startup I run it in IE 9 but then IE 9 asks me to install silverlight I said OK at the end it says it cannot install because it's already installed so in the end I cannot run the app.
Is this clearly a bug ? Is it possible to fix this as this app was developer maybe in older version of silverlight ?
Try downloading the very latest (Feb 2011) developer runtime for Silverlight 4 which is found here.

SilverLight project missing in solutiuon explorer

I had project in VS2008 with Silverlight 3.0 but when i installed 4.0 and uninstalled 3.0 its not working "Its not loading the project in solution explorer " [I hav installed both SDK and Tool Kit]
I wouldn't recommend uninstall Silverlight 3.0 SDK. In fact installing VS2010 will install Silverlight 3 and its SDK.
My guess is you've upgraded the solution and project files but its still a a Silverlight 3 project, VS2010 is quite happy to support the development of Silverlight 3. With the Silverlight 3 SDK being missing it can't find any of the references it needs.
With the Silveright 4.0 tools installed, go to the Silverlight project's properties Silverlight page and set Target Silverlight Version to "Silverlight 4".
