I have an extensive ASP.NET Sqlite driven application that will run through Apache with the help of Mono. For testing purposes, I created an application that has two textboxes and a button. When the textboxes are filled with text and the button is executed, a Sqlite table will receive the text within the textboxes. This test application works in Visual Studio.
I published the test application and placed it on the apache server. The Sqlite .db file sits in the bin folder, and my connection string points directly to this folder. When I run the application, the textboxes and button show up, but when I press the button I receive the following error:
Server Error in '/' Application

The system.data.sqlite.dll file is actually in the bin with the sqlite .db file. Does anyone know how to resolve this error?
Thank you,
DFM
This managed version of the ADO.NET provider for SQLite requires the native
sqlite3.dll or Linux shared library from http://www.sqlite.org It looks like the dll is missing: "DllNotFoundException"

These are the newest versions of each of these packages, but I have also tried matching NUnit's version to the TestAdapter's version (3.10.0). The most baffling part of this is that Visual Studio's Test Explorer has no problem running the tests! I would very much like to use ReSharper's explorer to easily run their profiling and coverage tools on my tests.
Moreover, at some point in time ReSharper's test explorer used to work, but I'm not aware of the particular version combination that led to it. This setup still works for basic [Test] style tests and only fails for [TestCaseSource] tests.
ETA: ReSharper is also not running namespace-level setup and tear-down fixtures. Maybe this is part of the problem?
How do I fix this?
This was a bug. JetBrains fixed it in ReSharper 2018.2 EAP 5. It's still finicky, but when it works, it works.
I get this when building .apk in Unity. I've tried to restart the PC, run Unity with Administrator privileges but it doesn't work. I'm lost.

Any help appreciated!
I've had this on occasion. My fix is to either change the version of the app in peeferences or to erase the app from my device.
Sometimes, it is as simple as restarting Unity.
Okay so, I have been given the responsibility to migrate a website with multiple applications to another server. That migration went well (all applications working). However, the performance of that new server was sub par (whole other story). We decided to migrate it again. This time everything is working very well-- except one application.
It worked just fine on the first and second IIS servers, but is refusing to cooperate this time around.
I've mirrored all the config settings that I could find from the working server:
windows authentication enabled: check
Impersonation disabled: check
applicationpool settings match: check
I just don't know what I'm missing; why would it work on one server, but not the other.

Please help, none of the other forum posts I've found have posted solutions that work for me.
I'm transferring a .NET Framework 4.0 site from 1 web host to another. The site on the existing hosting seems to be working as intended. However, after transferring the site files and database to the new hosting and then fixing the web.config connection string to point to the new db, I'm getting errors when trying to access a page that pulls from the database.
I did not write the site, but it appears to be using a code-first setup.

I've tried rebuilding the edmx file from the new database server after transferring the files. I know my connection string is working because I wrote a small test that connects to the database through the same connection string and it is able to retrieve data.
The only change I've made to the code base after copying it from it's working state is to the web.config's db connection string.
The only real notable difference from the old hosting versus the new hosting is that the old hosting was using SQLEXPRESS(unknown version), whereas the new hosting is using MSSQL 2008.

I'm playing around with MonoDev on my mac and wanting to see how well it can run basic ASP.NET applications which I've worked on.
I chose a very basic site, it's got a handful of ASP.NET pages, all of which inherit nested master pages and some ASP.NET AJAX stuff. The project is .NET 2.0 and I have the web.config set appropriately for ASP.NET AJAX 1.0.
Under windows this runs without any dramas and because it's so simple I expected it to "just work" in MonoDev too. The problem is that when I run using the built-in web server for MonoDev I get the following exception:

It seems though that when I remove my ScriptManager from my root master page everything runs fine (well except for the JavaScript which expects it to be there).
Being completely new to Mono & MonoDev I don't really know where to start with debugging other than getting to the point I'm currently at.
I had the same problem when doing some Mono testing and the problem was the scriptmanager was not inside the form runat="server" id="form1" /form tags. Once that was added the NULL exception went away.
